Content: Centralists replaced Federalists in 1828. A Federalist revolt in 1829 put Vicente Guerrero in the presidential chair, but he was soon overthrown by the Centralists, who held power until 1832. In 1833 another change placed Federalists in power until 1836, when Centralists again regained control and held it for nearly a decade. The age of Santa Anna: Texas and the Mexican-American War
After the downfall of Iturbide, Mexican politics revolved for some time about the enigmatic personality of the charismatic Antonio López de Santa Anna, who seemingly had few fixed ideological or political beliefs. Allied with the Federalists, Santa Anna was first chosen president in 1833, but, rather than serve, he placed the liberal vice president, Valentín Gómez Farías, at the head of the government until Farías and his group in 1834 attacked the privileges of the clergy. Then Santa Anna assumed his presidential post and nullified the anticlerical legislation. Before his political career ended he would be in and out of the presidency 10 more times. Santa Anna was president when difficulties over Texas first began to mount. Under favourable terms, some 30,000 U.S. immigrants had populated that previously desolate area.
