In the two decades after the 1834 collapse of the federal republic, Santa Anna dominated Mexico's politics. Between 1833 and 1855, the caudillo occupied the presidency eleven times, completing none of his terms and frequently leaving the government in the hands of weak caretaker administrations. During this period, Mexico went to war on three separate occasions and lost half of its territory through sale or military defeat. Fiscal insufficiency kept Mexico constantly on the verge of bankruptcy and foreign military intervention.

Santa Anna repeatedly rose to the presidency, only to be cast out in the wake of scandals and military defeats. Invariably, he returned--even from exile--to lead the republic once more into military glory or out of insolvency. Santa Anna's bravery, energy, and organizational abilities were often matched by his vanity, cruelty, and opportunism. His feats of heroism in victorious battle, his bold interventions in the political life of the country, and his countless shifts from one side of the political spectrum to the other responded to the insecurities of Mexican nationalists and the vacillations of the republic's fractious political class.

The Constitution of 1836

Upon assuming dictatorial powers, Santa Anna promptly annulled Gómez Farías's reforms and abolished the constitution of 1824. The authoritarian principles that underlay Santa Anna's rule were subsequently codified in the constitution of 1836, also known as the Siete Leyes (Seven Laws). Under the constitution of 1836, Mexico became a centralist regime in which power was concentrated in the president and his immediate subordinates. The states of the former federal republic were refashioned as military districts administered by regional caudillos appointed by the president, and property qualifications were decreed for congressional officeholders and voters.

The nationalist and authoritarian style of the new centralist regime soon brought it into conflict with the loosely governed lands of Mexico's northern frontier. Santa Anna's efforts to exert central authority over the English-speaking settlements in the northern state of Coahuila-Tejas eventually collided with the growing assertiveness of the frontier population that described itself as Texan.
