After Mexico's defeat in the
Mexican–American War, the country was beset by despair and political chaos. Abhorring long-term exploitation and short-term heavy taxes needed to finance the war, some indigenous peoples revolted in the
Sierra Gorda region (1847–1849) and in the
Yucatán peninsula (1847–1852). The north of Mexico was especially devastated. The territorial losses to the United States codified in the
Treaty of Guadalupe Hidalgo were an impetus for
Apache and
Comanche raids in northern Mexico. The region was further weakened by depopulation, with the discovery of gold in the recently lost territory of California prompting inhabitants of northern Mexico to migrate there. During this chaos,
José María Tornel and Juan Suárez y Navarro founded the Santanista party. The Santanistas believed that Mexico should be ruled by a strong dictator who would create a centralized state that would emphasize the importance of the Catholic faith. Conservative politician and historian
Lucas Alamán stated that the Church was "the only tie left that unites the Mexican people." The Santanistas hoped that exiled President Santa Anna would be that strong dictator. The Santanistas, with help from the radical
puros and the military, overthrew the
moderado Mariano Arista. Santa Anna arrived in Veracruz on 1 April 1853, and he took office upon reaching Mexico City on 20 April. Upon taking office yet again, Santa Anna took measures to improve the army, hoping to create a standing army of 90,000 men. However, due to the unpopularity of the draft and the low quality of the troops who were recruited, Santa Anna lowered his goal to 46,000 troops. Mexican Liberals whom Santa Anna considered threats, notably Benito Juárez and
Melchor Ocampo, were forced into exile to the U.S. Juárez and Ocampo settled in New Orleans and plotted to overthrow the government. Santa Anna also introduced tax increases to boost revenue. On 14 May 1853, a decree was promulgated that renewed all taxes and added new ones, such as the restoration of the
alcabala (sales tax) and the abolition of financial concessions to the port of
Acapulco and to Yucatán. Santa Anna had some successful policies, such as measures that reduced banditry and improved the country's highway system. However, he became increasingly
authoritarian as well as pompous, adopting the title of "
Most Serene Highness." His popularity also declined due to the tax increases that he implemented, his suppression of political opposition, and his regime's rampant corruption. A key event that further decreased his popularity was the
Gadsden Purchase, in which the United States paid $10,000,000 to Mexico in exchange for more Mexican land. It has been speculated that Santa Anna took $600,000 of the indemnity for himself. Santa Anna was further weakened by the deaths of many advisors and the alienation of others, as exemplified by his decision to exile Suárez y Navarro. ==Plan of Ayutla is drafted==
