Spanish attempts to reconquer Mexico in the context of "Anastasio Bustamante"

Trinidad Anastasio de Sales Ruiz Bustamante y Oseguera (Spanish pronunciation: [anasˈtasjo βustaˈmante]; 27 July 1780 – 6 February 1853) was a Mexican physician, general, and politician who served as the 4th President of Mexico three times from 1830 to 1832, 1837 to 1839, and 1839 to 1841. He also served as the 2nd Vice President of Mexico from 1829 to 1832 under Presidents Vicente Guerrero, José María Bocanegra, himself, and Melchor Múzquiz. He participated in the Mexican War of Independence initially as a royalist before siding with Agustín de Iturbide and supporting the Plan of Iguala.

Bustamante was a member of the Provisional Government Junta, the first governing body of Mexico. After the fall of the First Mexican Empire, his support for Emperor Iturbide was pardoned by President Guadalupe Victoria. The controversial 1828 general election sparked riots forcing the results to be nullified, as a result, Congress named him vice president while the liberal Vicente Guerrero was named president. Bustamante's command of a military reserve during the Barradas Expedition in 1829 allowed him to launch a coup d'état ousting Guerrero.
