Revolt of the Polkos

In February 1847, five Mexican National Guard regiments rose up in rebellion against the Mexican government, in protest over legislation that permitted the government to requisition money and property from the Catholic Church. Led by General Matías Peña y Barragán, the group issued a set of demands which included the resignation of the President and Vice President of Mexico. When the demands were not met, fighting broke out in Mexico City. President Antonio Lopez de Santa Anna was able to negotiate a peaceful solution with the rebels in March 1847.

Background
On January 11, 1847, Mexican president Valentín Gómez Farías signed legislation authorizing the government to requisition up to fifteen million pesos worth of Catholic Church property. This move which was intended to help finance the Mexican-American War drew criticism from the Catholic Church, large landowners, and military leaders. When National Guard units stationed in Mexico City expressed dissatisfaction with his policy, Gómez Farías ordered them to the front lines - a move that resulted in open rebellion.

Rebellion
On February 26, General Matías Peña y Barragán led five National Guard regiments in revolt. Other prominent members of the rebellion included José Mariano Salas and Pedro María de Anaya. The leaders of the rebellion issued a plan demanding the resignation of President Gómez Farías as well as declaring the anti-clerical January law null. Historians would later discover that two prominent Catholic priests provided funding for the revolt. Members of the five National Guard units included sons of doctors, lawyers, merchants, and other aristocracy. As such, the rebels were known by their enemies as "polkos", a name that seems to have derived from the polka dance, which was popular in elite society. The term was also reminiscent of U.S. President, James K. Polk.

Rejecting an offer of amnesty from Gómez Farías on the second day of the revolt, the rebels took control of several church buildings in Mexico City, while the government's forces controlled the National Palace, the cathedral, and the university. After ten days of street fighting, the rebels reduced their demands to only one: the removal of Gómez Farías from office.

On March 11, General Santa Anna, who was currently leading the Mexican Army on the front lines, sent troops to Mexico City to restore order. He returned to the capital soon after, and forged a peace settlement with Peña y Barragán and the other leaders of the Rebellion. Per the peace settlement, Congress abolished the office of vice president, thereby removing Gómez Farías from office, and named rebel leader Pedro Maria Anaya "substitute president." Santa Anna also agreed to the repeal of the January 11 law in exchange for a donation of 1.5 million pesos from the Church to fund the war effort.

The revolt revealed the high degree of influence which the Catholic Church exerted over the republic of Mexico. It also exposed long-standing rifts among Mexico's political elites at a time when unity was needed most.
