Alberto Octavio Tserclaes de Tilly

Alberto Octavio Tserclaes de Tilly (also known as Antonio) (1646 – 10 September 1715) was a Spanish general of Flemish origins, the grandson of a brother of General Johann Tserclaes Count of Tilly, who acquired fame in the Thirty Years War.

Biography
In 1693 he was granted the title of prince by King Charles II of Spain. He took part in the Spanish War of Succession (1701–1714) on the side of the young French-born Prince, later King Philip V of Spain against his opponent Charles VI of Austria of the Habsburgs. He fought in the Portuguese campaign during 1704, during which he advanced along the left bank of the river Tagus, conquering Portalegre and consolidating the Alentejo region, while the young Philip and James FitzJames, 1st Duke of Berwick advanced along the right bank of the river.

In 1705 there was a conspiracy in which Diego Dávila Mesía y Guzmán, Captain General of Cataluña, sided with Charles of Austria. Alberto Octavio warned the central authorities. For this assistance, Philip V of Spain bestowed upon him in 1706 the title of Grandee of Spain, a title which included the privilege of remaining covered or seated in the presence of royalty.

Antonio Octavio served as Viceroy of Navarre in 1706–1709 and as Captain General of Aragon in 1711–1714.

In 1714 he was appointed Captain General of Cataluña, replacing FitzJames. He died in Barcelona the following year.
