Antonio López de Santa Anna (1794–1876) was a dominant and controversial Mexican general and statesman who served as President of Mexico on multiple non-consecutive occasions between 1833 and 1855 with dictator like serving style. Often referred to as "the Napoleon of the West" or an "uncrowned monarch," he was a central figure in the turbulent decades following Mexican independence, known for shifting political alliances and leading Mexican forces in several major conflicts. 

Rise to Power and Early Military Service

Santa Anna began his career in the Spanish army in 1810, fighting against Mexican independence, but switched sides in 1821 to join the rebel forces. He gained national prestige by repelling a Spanish attempt to reconquer Mexico in 1829, earning the nickname "Hero of Tampico," which helped him win his first presidential election in 1833.

Political Instability and Dictatorship

His political life was marked by opportunism, serving as president a total of 11 times, though his combined time in office was relatively short. He often assumed dictatorial powers, which led to numerous rebellions and exiles.
