Zachary Taylor

Zachary Taylor (November 24, 1784 – July 9, 1850) was the 12th President of the United States (1849–1850) and an American military leader. His 40-year military career ended with far-reaching victories in the Mexican–American War. His status as a national hero won him election to the White House despite his vague political beliefs. His top priority as president was preserving the Union, but he died 16 months into his term, before making any progress on the status of slavery, which had been inflaming tensions in Congress.

Taylor was born to a prominent family of planters who migrated westward from Virginia to Kentucky in his youth. He was commissioned as a U.S. Army officer in 1808 and made a name for himself as a captain in the War of 1812. He climbed the ranks establishing military forts along the Mississippi River and entered the Black Hawk War as a colonel in 1832. His success in the Second Seminole War attracted national attention and earned him the nickname "Old Rough and Ready".

In 1845, as the annexation of Texas was underway, President James K. Polk dispatched Taylor to the Rio Grande area in anticipation of a potential battle with Mexico over the disputed Texas-Mexico border. The Mexican–American War broke out in May 1846, and Taylor led American troops to victory in a series of battles culminating in the Battle of Palo Alto and the Battle of Monterrey. He became a national hero, and political clubs sprung up to draw him into the upcoming 1848 presidential election.

The Whig Party convinced the reluctant Taylor to lead their ticket, despite his unclear platform and lack of interest in politics. He won the election alongside U.S. Representative Millard Fillmore of New York, defeating Democratic candidate Lewis Cass. As president, Taylor kept his distance from Congress and his cabinet, even as partisan tensions threatened to divide the Union. Debate over the slave status of the large territories claimed in the war led to threats of secession from Southerners. Despite being a Southerner and a slaveholder himself, Taylor did not push for the expansion of slavery. To avoid the question, he urged settlers in New Mexico and California to bypass the territorial stage and draft constitutions for statehood, setting the stage for the Compromise of 1850. Taylor died suddenly of a stomach-related illness in July 1850, ensuring he would have little impact on the sectional divide that led to civil war a decade later.

Early life and family
Taylor was born on November 24, 1784, on a plantation in Orange County, Virginia, to a prominent family of planters of English ancestry. He is believed to have been born, inconclusively, at the home of his maternal grandfather, Hare Forest Farm. He was the third of five surviving sons in his family (a sixth died in infancy) and had three younger sisters. His mother was Sarah Dabney (Strother) Taylor. His father, Richard Taylor, had served as a lieutenant colonel in the American Revolution. Taylor was a descendant of Elder William Brewster, the Pilgrim colonist leader of the Plymouth Colony, a Mayflower immigrant, and one of the signers of the Mayflower Compact; and Isaac Allerton Jr., a colonial merchant and colonel who was the son of Mayflower Pilgrim Isaac Allerton and Fear Brewster. Taylor's second cousin through that line was James Madison, the fourth president.

Leaving exhausted lands, his family joined the westward migration out of Virginia and settled near what developed as Louisville, Kentucky, on the Ohio River. Taylor grew up in a small woodland cabin before his family moved to a brick house with increased prosperity. The rapid growth of Louisville was a boon for Taylor's father, who came to own 10000 acre throughout Kentucky by the start of the 19th century; he held 26 slaves to cultivate the most developed portion of his holdings. There were no formal schools on the Kentucky frontier, and Taylor had a sporadic formal education. A schoolmaster recalled Taylor as a quick learner. His early letters show a weak grasp of spelling and grammar, and his handwriting was later described as "that of a near illiterate".

In June 1810, Taylor married Margaret Mackall Smith, whom he had met the previous autumn in Louisville. "Peggy" Smith came from a prominent family of Maryland planters; she was the daughter of Major Walter Smith, who had served in the Revolutionary War. The couple had six children:


 * Ann Margaret Mackall Taylor (1811–1875), married Robert C. Wood, a U.S. Army surgeon she had met while living Fort Snelling, in 1829.
 * Sarah Knox Taylor (1814–1835), married Jefferson Davis in 1835, whom she had met through her father at the end of the Black Hawk War; she died at 21 of malaria in St. Francisville, Louisiana, shortly after her marriage.
 * Octavia Pannill Taylor (1816–1820)
 * Margaret Smith Taylor (1819–1820), died in infancy along with Octavia when the Taylor family was stricken with a "bilious fever"
 * Mary Elizabeth Taylor (1824–1909), married William Wallace Smith Bliss (died 1853) in 1848
 * Richard "Dick" Taylor (1826–1879), Confederate Army general during the Civil War

Military career
On May 3, 1808, Taylor joined the U.S. Army, receiving a commission as a first lieutenant of the Seventh Infantry Regiment. He was among the new officers commissioned by Congress in response to the Chesapeake–Leopard Affair, in which an American frigate had been boarded by the crew of a British warship, sparking calls for war. Taylor spent much of 1809 in the dilapidated camps of New Orleans and nearby Terre aux Boeufs. He was promoted to captain in November 1810. His army duties were limited at this time, and he attended to his personal finances. Over the next several years, he began to purchase slaves and a good deal of bank stock in Louisville. In July 1811 he was called to the Indiana Territory, where he assumed control of Fort Knox after the commandant fled. In only a few weeks, he was able to restore order in the garrison, for which he was lauded by Governor William Henry Harrison.

During the War of 1812, in which U.S. forces battled the British Empire and its Indian allies, Taylor successfully defended Fort Harrison in Indiana Territory from an Indian attack commanded by the Shawnee chief Tecumseh. Taylor gained recognition and received a brevet (temporary) promotion to the rank of major. Later that year he joined General Samuel Hopkins as an aide on two expeditions: the first into the Illinois Territory and the second to the Tippecanoe battle site, where they were forced to retreat in the Battle of Wild Cat Creek. Taylor moved his growing family to Fort Knox after the violence subsided. In spring 1814, he was called back into action under Brigadier General Benjamin Howard. That October he supervised the construction of Fort Johnson, the last toehold of the U.S. Army in the upper Mississippi River Valley. Upon Howard's death a few weeks later, Taylor was ordered to abandon the fort and retreat to Saint Louis. Reduced to the rank of captain when the war ended in 1814, he resigned from the army. He re-entered it a year later after gaining a commission as a major.

For two years, Taylor commanded Fort Howard at the Green Bay, Wisconsin settlement. He then returned to Louisville and his family. In April 1819 he was promoted to the rank of lieutenant colonel and dined with President James Monroe. In late 1821, Taylor took the 7th Infantry to Natchitoches, Louisiana, on the Red River. On the orders of General Edmund P. Gaines, they set out to locate a new post more convenient to the Sabine River frontier. By the following March, Taylor had established Fort Jesup, at the Shield's Spring site southwest of Natchitoches. That November he was transferred to Fort Robertson at Baton Rouge, where he remained until February 1824. He spent the next few years on recruiting duty. In late 1826 he was called to Washington, D.C., to work on an Army committee to consolidate and improve military organization. In the meantime he acquired his first Louisiana plantation and decided to move with his family to Baton Rouge as their home.

In May 1828, Taylor was called back to action, commanding Fort Snelling in Minnesota on the northern Mississippi River for a year, and nearby Fort Crawford for a year. After some time on furlough, when he expanded his landholdings, Taylor was promoted to colonel of the 1st Infantry Regiment in April 1832. At that time, the Black Hawk War was beginning in the West. Taylor campaigned under General Henry Atkinson to pursue and later defend against Chief Black Hawk's forces throughout the summer. The end of the war in August 1832 signaled the end of Indian resistance to U.S. expansion in the area, and the following years were relatively quiet. During this period Taylor resisted the courtship of his 17-year-old daughter Sarah Knox Taylor and Lieutenant Jefferson Davis. He respected Davis but did not approve of his daughter becoming a military wife, as he knew it was a hard life for families. Davis and Sarah Taylor married in June 1835, but she died three months later of malaria contracted on a summer visit to Davis' sister in St. Francisville, Louisiana.

By 1837, the Second Seminole War was underway when Taylor was directed to Florida. He defeated the Seminole Indians in the Christmas Day Battle of Lake Okeechobee, which was among the largest U.S.–Indian battles of the nineteenth century. He was promoted to brigadier general in recognition of his success. In May 1838, Brig. Gen. Thomas Jesup stepped down and placed Taylor in command of all American troops in Florida, a position he held for two years. His reputation as a military leader was growing, and with it, he began to be known as "Old Rough and Ready." After his long-requested relief was granted, Taylor spent a comfortable year touring the nation with his family and meeting with military leaders. During this period, he began to be interested in politics and corresponded with President William Henry Harrison. He was made commander of the Second Department of the Army's Western Division in May 1841. The sizable territory ran from the Mississippi River westward, south of the 37th parallel north. Stationed in Arkansas, Taylor enjoyed several uneventful years, spending as much time attending to his land speculation as to military matters.

Mexican–American War


In anticipation of the annexation of the Republic of Texas, which had established independence in 1836, Taylor was sent in April 1844 to Fort Jesup in Louisiana. He was ordered to guard against any attempts by Mexico to reclaim the territory. He served there until July 1845, when annexation became imminent, and President James K. Polk directed him to deploy into disputed territory in Texas, "on or near the Rio Grande" near Mexico. Taylor chose a spot at Corpus Christi, and his Army of Occupation encamped there until the following spring in anticipation of a Mexican attack.

Taylor's men advanced to the Rio Grande in March 1846. Polk's attempts to negotiate with Mexico had failed, and war appeared imminent. Violence broke out several weeks later, when some of Captain Seth B. Thornton's men were attacked by Mexican forces near the river. Polk, learning of the Thornton Affair, told Congress in May that a war between Mexico and the U.S. had begun. That same month, Taylor commanded American forces at the Battle of Palo Alto and the nearby Battle of Resaca de la Palma, defeating the Mexican forces, which greatly outnumbered his own. These victories made him a popular hero, and within weeks he received a brevet promotion to major general and a formal commendation from Congress. The national press compared him to George Washington and Andrew Jackson, both generals who had ascended to the presidency, although Taylor denied any interest in running for office. "Such an idea never entered my head," he remarked in a letter, "nor is it likely to enter the head of any sane person."

In September, Taylor inflicted heavy casualties upon the Mexican defenders at the Battle of Monterrey. The city of Monterrey had been considered "impregnable", but was captured in three days, forcing Mexican forces to retreat. Taylor was criticized for signing a "liberal" truce, rather than pressing for a large-scale surrender. Afterwards, half of Taylor's army was ordered to join General Winfield Scott's soldiers as they besieged Veracruz. Mexican General Antonio López de Santa Anna discovered, through an intercepted letter from Scott, that Taylor had contributed all but 6,000 of his men to the effort. His remaining force included only a few hundred regular army soldiers, and Santa Anna resolved to take advantage of the situation. Santa Anna attacked Taylor with 20,000 men at the Battle of Buena Vista in February 1847, leaving around 700 Americans dead or wounded at a cost of over 1,500 Mexican. Outmatched, the Mexican forces retreated, ensuring a "far-reaching" victory for the Americans. Taylor remained at Monterrey until late November 1847, when he set sail for home. While he would spend the following year in command of the Army's entire western division, his active military career was over. In December he received a hero's welcome in New Orleans and Baton Rouge, and his popular legacy set the stage for the 1848 presidential election.

Election of 1848
In his capacity as a career officer, Taylor had never reportedly revealed his political beliefs before 1848 nor voted before that time. He thought of himself as an independent, believing in a strong and sound banking system for the country, and thought that President Andrew Jackson should not have allowed the Second Bank of the United States to collapse in 1836. He believed it was impractical to talk about expanding slavery into the western areas of the U.S., as he concluded that neither cotton nor sugar (both were produced in great quantities as a result of slavery) could be easily grown there through a plantation economy. He was also a firm nationalist, and due to his experience of seeing many people die as a result of warfare, he believed that secession was not a good way to resolve national problems. Taylor, although he did not agree with their stand against protective tariffs and expensive internal improvements, aligned himself with Whig Party governing policies: the President should not be able to veto a law, unless that law was against the Constitution; that the office should not interfere with Congress; and that the power of collective decision-making, as well as the Cabinet, should be strong.



Well before the American victory at Buena Vista, political clubs were formed which supported Taylor for President. His support was drawn from an unusually broad assortment of political bands, including Whigs and Democrats, Northerners and Southerners, allies and opponents of national leaders such as Henry Clay and James K. Polk. By late 1846 Taylor's opposition to a presidential run began to weaken, and it became clear that his principles more closely resembled Whig orthodoxy. Still, he maintained that he would only accept election as a national, independent figure, rather than a partisan loyalist. Taylor declared, as the 1848 Whig Party convention approached, that he had always been a Whig in principle, but he did consider himself a Jeffersonian-Democrat. Many southerners believed that Taylor supported slavery and its expansion into the new territory absorbed from Mexico, and some were angered when Taylor suggested that if he were elected President he would not veto the Wilmot Proviso, which proposed against such an expansion. This position did not enhance his support from activist antislavery elements in the Northern U.S., as these wanted Taylor to speak out strongly in support of the Proviso, not simply fail to veto it. Most abolitionists did not support Taylor, since he was a slave-owner. Many southerners also knew that Taylor supported states' rights and was opposed to protective tariffs and government spending for internal improvements. The Whigs hoped that he put the federal union of the United States above all else.

Taylor received the Whig nomination for President in 1848. For his Vice Presidential nominee the convention chose Millard Fillmore, a prominent New York Whig who had chaired the House Ways and Means Committee and had been a contender for Henry Clay's Vice Presidential nominee in the 1844 election. Fillmore's selection was largely an attempt at reconciliation with northern Whigs, who were furious at the election of a slaveowning southerner; all factions of the party were dissatisfied with the final ticket. Taylor continued to minimize his role in the campaign, preferring not to directly meet with voters or correspond regarding his political views. His campaign was skillfully directed by Senator John J. Crittenden of Kentucky, a friend and early political supporter, and bolstered by a late endorsement from Senator Daniel Webster of Massachusetts. Taylor defeated Lewis Cass, the Democratic candidate, and Martin Van Buren, the Free Soil candidate.

Taylor ignored the Whig platform, as historian Michael F. Holt explains: "Taylor was equally indifferent to programs Whigs had long considered vital. Publicly, he was artfully ambiguous, refusing to answer questions about his views on banking, the tariff, and internal improvements. Privately, he was more forthright. The idea of a national bank "is dead, and will not be revived in my time." In the future the tariff "will be increased only for revenue"; in other words, Whig hopes of restoring the protective tariff of 1842 were vain. There would never again be surplus federal funds from public land sales to distribute to the states, and internal improvements "will go on in spite of presidential vetoes." In a few words, that is, Taylor pronounced an epitaph for the entire Whig economic program."

Transition and inauguration
As president-elect, Taylor kept his distance from Washington, not resigning his Western Division command until late January 1849. He spent the months following the election formulating his cabinet selections. He was deliberate and quiet about his decisions, to the frustration of his fellow Whigs. While he despised patronage and political games, he endured a flurry of advances from office-seekers looking to play a role in his administration.

While he would not appoint any Democrats, Taylor wanted his cabinet to reflect the nation's diverse interests, and so apportioned the seats geographically. He also avoided choosing prominent Whigs, sidestepping such obvious selections as Henry Clay. He saw Crittenden as a cornerstone of his administration, offering him the crucial seat of Secretary of State, but Crittenden insisted on serving out the Governorship of Kentucky to which he had just been elected. Taylor settled instead on Senator John M. Clayton of Delaware, a close associate of Crittenden's.

Taylor began his trek to Washington in late January, a journey rife with bad weather, delays, injuries, and sickness. Taylor finally arrived in the nation's capital on February 24 and soon met with the outgoing President Polk. The incumbent Democrat held a low opinion of Taylor, privately deeming him "without political information" and "wholly unqualified for the station" of President. Taylor spent the following week meeting with political elites, some of whom were unimpressed with his appearance and demeanor. With less than two weeks until his inauguration, he met with Clayton and hastily finalized his cabinet.

Taylor's term as president began Sunday, March 4, but his inauguration was not held until the following day out of religious concerns. His inauguration speech discussed the many tasks facing the nation, but presented a governing style of deference to Congress and sectional compromise instead of assertive executive action. Throughout the summer of 1849, Taylor toured the northeastern U.S., to familiarize himself with a region of which he had seen little. He spent much of the trip plagued by gastrointestinal illness and returned to Washington by September.

Sectional crisis
As Taylor took office, Congress faced a battery of questions related to the Mexican Cession, comprising three major territories acquired by the U.S. after the Mexican War: California, New Mexico, and Utah. It was unclear which of the acquisitions would achieve statehood and which would remain federal territories, while the question of their slave status threatened to bitterly divide Congress. While a southern slaveowner himself, Taylor had no particular bias toward the southern faction of Congress which sought to maintain its right to slavery. His major goal was sectional peace, preserving the Union through legislative compromise. As the threat of Southern secession grew, he sided increasingly with northern abolitionists such as Senator William H. Seward of New York, even suggesting that he would sign the Wilmot Proviso to ban slavery in federal territories should such a bill reach his desk.



In Taylor's view, the best way forward was to admit California as a state rather than a federal territory, as it would leave the slavery question out of Congress's hands. The timing for statehood was in Taylor's favor, as the Gold Rush was well underway at the time of his inauguration, and California's population was exploding. The administration dispatched Rep. Thomas Butler King to California, to test the waters and advocate on behalf of statehood, knowing that the Californians were certain to adopt an anti-slavery constitution. King found that a constitutional convention was already underway, and by October 1849, the convention unanimously agreed to join the Union—and to ban slavery within their borders.

The question of the New Mexico–Texas border was unsettled at the time of Taylor's inauguration. The territory newly won from Mexico was under federal jurisdiction, but the Texans claimed a swath of land north of Santa Fe and were determined to include it within their borders, despite having no significant presence there. Taylor sided with the New Mexicans' claim, initially pushing to keep it as a federal territory, but eventually supported statehood so as to further reduce the slavery debate in Congress. The Texas government, under newly instated governor P. Hansborough Bell, tried to ramp up military action in defense of the territory against the federal government, but was unsuccessful.

The Latter Day Saint settlers of modern-day Utah had established a provisional State of Deseret, an enormous swath of territory which had little hope of recognition by Congress. The Taylor administration considered combining the California and Utah territories, but instead opted to organize the Utah Territory. To alleviate the Mormon population's concerns over religious freedom, Taylor promised they would have relative independence from Congress despite being a federal territory.

Taylor sent his first and only State of the Union report to Congress in December 1849. He recapped international events and suggested several adjustments to tariff policy and executive organization, but such issues were overshadowed by the sectional crisis facing Congress. He reported on California's and New Mexico's applications for statehood, and recommended that Congress approve them as written and "should abstain from the introduction of those exciting topics of a sectional character". The policy report was prosaic and unemotional, but ended with a sharp condemnation of secessionists. It had no effect on Southern legislators, who saw the admission of two free states as an existential threat, and Congress remained stalled.

Foreign affairs
Taylor and his Secretary of State, John M. Clayton, both lacked diplomatic experience, and came into office at a relatively uneventful time in American–international politics. Their shared nationalism allowed Taylor to devolve foreign policy matters to Clayton with minimal oversight, although no decisive foreign policy was established under their administration. As opponents of the autocratic European order, they vocally supported German and Hungarian liberals in the revolutions of 1848, although they offered little in the way of aid. A perceived insult from the French minister Guillaume Tell Poussin nearly led to a break in diplomatic relations until Poussin was replaced, and a reparation dispute with Portugal resulted in harsh words from the Taylor administration. In a more positive effort, the administration arranged for two ships to assist in the United Kingdom's search for a team of British explorers, led by John Franklin, who had gotten lost in the Arctic. While previous Whig administrations had emphasized Pacific trade as an economic imperative, the Taylor administration took no major initiative in the Far East.

Throughout 1849 and 1850, they contended with Narciso López, the Venezuelan radical who led repeated filibustering expeditions in an attempt to conquer the island of Cuba. While López made generous offers to American military leaders to support him, Taylor and Clayton saw the enterprise as illegal. They issued a blockade, and later, authorized a mass arrest of López and his fellows, although the group would eventually be acquitted. They also confronted Spain, which had arrested several Americans on the charge of piracy, but the Spaniards eventually surrendered them to maintain good relations with the U.S.

The definitive foreign policy accomplishment of the Taylor administration was the Clayton–Bulwer Treaty, regarding a proposed inter-oceanic canal through Central America. While the U.S. and Britain were on friendly terms, and the construction of such a canal was decades away from reality, the mere possibility put the two nations in an uneasy position. For several years, Britain had been seizing strategic points, particularly the Mosquito Coast on the eastern coast of present-day Nicaragua. Negotiations were held with Britain that resulted in the landmark Clayton–Bulwer Treaty. Both nations agreed not to claim control of any canal that might be built in Nicaragua. The treaty promoted development of an Anglo-American alliance; its completion was Taylor's last action as president.

Compromise attempts and final days


Senate Majority Leader Henry Clay took a central role as Congress debated the statehood question. While his positions had some overlap with Taylor's, the president always maintained his distance from Clay. Historians disagree on his motivations for doing so. With assistance from Senator Daniel Webster of Massachusetts, Clay developed his landmark proposal, the Compromise of 1850. The proposal allowed statehood for California, giving it independence on the slavery question, while the other territories would remain under federal jurisdiction. This would include the disputed parts of New Mexico, although Texas would be reimbursed for the territory. Slavery would be retained in the District of Columbia, but the slave trade would be banned. Meanwhile, a strict Fugitive Slave Law would be enacted, bypassing northern legislation which had restricted Southerners from retrieving runaway slaves. Tensions flared as Congress negotiated and secession talks grew, culminating with a threat from Taylor to send troops into New Mexico to protect its border from Texas. The omnibus law was a major step forward but ultimately could not pass, due to extremists on both sides.

No great compromise reached Taylor's desk during his presidency; instead, his last days were overshadowed by the Galphin affair. Before joining the Taylor cabinet, Secretary of War George W. Crawford had served as a lawyer. He had been involved in a fifteen-year case, representing the descendants of a colonial trader whose services to the British crown had not been repaid at the time of the American Revolution. The British debt to George Galphin was to be assumed by the federal government, but Galphin's heirs only received payment on the debt's principal after years of litigation, and were unable to win an interest payment from the Polk administration.

Taylor's Treasury Secretary William M. Meredith, with the support of Attorney General Reverdy Johnson, finally signed off on the payment in April 1850. To the president's embarrassment, this payment included a legal compensation of nearly $100,000 to Crawford; two cabinet members had effectively offered a tremendous chunk of the public treasury to another. A House investigation cleared Crawford of any legal wrongdoing, but nonetheless expressed disapproval of his accepting the payment. Taylor, who had already been sketching out a re-organization of his cabinet, now had an unfolding scandal to complicate the situation.

Death
On July 4, 1850, Taylor reportedly consumed raw fruit, probably cherries, and iced milk after attending holiday celebrations and a fund-raising event at the Washington Monument, which was then under construction. Over the course of several days, he became severely ill with an unknown digestive ailment. His doctor "diagnosed the illness as cholera morbus, a flexible mid–nineteenth-century term for intestinal ailments as diverse as diarrhea and dysentery but not related to Asiatic cholera," the latter being a widespread epidemic at the time of Taylor's death. The identity and source of Taylor's illness are the subject of historical speculation (see below), although it is known that several of his cabinet members had come down with a similar illness. Despite treatment, Taylor died at 10:35 p.m. on July 9, 1850. He was 65 years old.

Taylor was interred in the Public Vault of the Congressional Cemetery in Washington, D.C. from July 13, 1850 to October 25, 1850. (It was built in 1835 to hold remains of notables until either the grave site could be prepared or transportation arranged to another city.) His body was transported to the Taylor Family plot where his parents are buried, on the old Taylor homestead plantation known as 'Springfield' in Louisville, Kentucky.

In 1883, the Commonwealth of Kentucky placed a fifty-foot monument in his honor near his grave; it is topped by a life-sized statue of Taylor. By the 1920s, the Taylor family initiated the effort to turn the Taylor burial grounds into a national cemetery. The Commonwealth of Kentucky donated two pieces of land for the project, turning the half-acre Taylor family cemetery into 16 acre. On May 6, 1926, the remains of Taylor and his wife (who died in 1852) were moved to the newly constructed Taylor mausoleum nearby. (It was made of limestone with a granite base, with a marble interior.) The cemetery property has been designated as the Zachary Taylor National Cemetery.

Assassination theories
Almost immediately after his death, rumors began to circulate that Taylor was poisoned by pro-slavery Southerners, and similar theories persisted into the twentieth century. In 1978, Hamilton Smith based his assassination theory on the timing of drugs, the lack of confirmed cholera outbreaks, and other material. In the late 1980s, Clara Rising, a former professor at University of Florida, persuaded Taylor's closest living relative, who was also the coroner of Jefferson County, Kentucky, to order an exhumation so that his remains could be tested. The remains were exhumed and transported to the Office of the Kentucky Chief Medical Examiner on June 17, 1991. Samples of hair, fingernail, and other tissues were removed, and radiological studies were conducted. The remains were returned to the cemetery and reinterred, with appropriate honors, in the mausoleum.

Neutron activation analysis conducted at Oak Ridge National Laboratory revealed no evidence of poisoning, as arsenic levels were too low. The analysis concluded Taylor had contracted "cholera morbus, or acute gastroenteritis", as Washington had open sewers, and his food or drink may have been contaminated. Any potential for recovery was overwhelmed by his doctors, who treated him with "ipecac, calomel, opium and quinine (at 40 grains a whack), and bled and blistered him too." Political scientist Michael Parenti questions the traditional explanation for Taylor's death, and, relying on interviews and reports by forensic pathologists, argues that the procedure used to test for arsenic poisoning was fundamentally flawed. A 2010 review concludes: "there is no definitive proof that Taylor was assassinated, nor would it appear that there is definitive proof that he was not."

Legacy


Because of his short tenure, Taylor is not considered to have strongly influenced the office of the Presidency or the U.S. Some historians believe that Taylor was too inexperienced with politics, at a time when officials needed close ties with political operatives. Despite his shortcomings, the Clayton–Bulwer Treaty affecting relations with Great Britain in Central America is "recognized as an important step in scaling down the nation's commitment to Manifest Destiny as a policy."

Taylor was the last President to own slaves while in office. He was the third of four Whig presidents, the last being Fillmore, his successor. Taylor was also the second president to die in office, preceded by William Henry Harrison who died while serving as President nine years earlier, as well as the only President elected from Louisiana.

The US Post Office released the first postage stamp issue honoring Zachary Taylor on June 21, 1875, 25 years after his death. In 1938, Taylor would appear again on a US Postage stamp, this time on the 12-cent Presidential Issue of 1938. Taylor's last appearance (to date, 2010) on a US postage stamp occurred in 1986 when he was honored on the AMERIPEX presidential issue. After Washington, Jefferson, Jackson and Lincoln, Zachary Taylor was the fifth American president to appear on US postage.

He is the namesake for several names and places throughout the United States, including:
 * Camp Taylor in Kentucky and Fort Taylor in Florida.
 * The SS Zachary Taylor, a World War II Liberty ship
 * Zachary Taylor Parkway in Louisiana and in Zachary Taylor Hall at Southeastern Louisiana University.
 * Taylor County in Georgia
 * Taylor County, Iowa
 * Rough and Ready, California
 * Zachary Taylor Highway in Virginia
