Central Republic, 1835

For conservatives, the liberal reform of Gómez Farías was radical and threatened the power of the elites. Santa Anna's actions in allowing this first reform (followed by a more sweeping one in 1855) might have been a test case for liberalism. At this point, Santa Anna was a liberal; by giving the moderate Gómez Farías responsibility for the reforms, he could have plausible deniability and closely monitor the reaction to a comprehensive attack on the special privileges of the army and the church, as well as confiscation of church wealth, enacted by Congress.

In May 1834, Santa Anna ordered the disarmament of the civic militia and urged Congress to abolish the controversial Ley del Caso. On 12 June he dissolved Congress and announced his decision to adopt the Plan of Cuernavaca, forming a new Catholic, centralist and conservative government. Santa Anna brokered a deal where, in exchange for preserving the privileges of the church and the army, the church promised a monthly donation to the government of 30,000–40,000 pesos. "The santanistas succeeded in achieving what the radicals had failed to do: forcing the Church to assist the republic's daily fiscal needs with its funds and properties."

On 4 January 1835, Santa Anna returned to his hacienda, placing Miguel Barragán as acting president. He soon replaced the 1824 constitution with the new document known as the " Siete Leyes " ("The Seven Laws"). Santa Anna did not involve himself with the conservative effort to replace the federalist constitution with a unitary central government, seemingly uneasy with their political path. "Although he has been blamed for the change to centralism, he was not actually present during any of the deliberations that led to the abolition of the federalist charter or the elaboration of the 1836 Constitution."

Several states openly rebelled against the changes, including Alta California, Nuevo México, Tabasco, Sonora, Coahuila y Tejas, San Luis Potosí, Querétaro, Durango, Guanajuato, Michoacán, Yucatán, Jalisco, Nuevo León, Tamaulipas, and Zacatecas. Several of these states formed their own governments: the Republic of the Rio Grande, the Republic of Yucatán, and the Republic of Texas. Their fierce resistance was possibly fueled by Santa Anna's reprisals committed against his defeated enemies. The New York Post editorialized that "had Santa Anna treated the vanquished with moderation and generosity, it would have been difficult if not impossible to awaken that general sympathy for the people of Texas which now impels so many adventurous and ardent spirits to throng to the aid of their brethren."

The Zacatecas militia, the largest and best supplied of the Mexican states, led by Francisco García Salinas, was well armed with.753 caliber British ' Brown Bess ' muskets and Baker.61 rifles. But, after two hours of combat on 12 May 1835, Santa Anna's "Army of Operations" defeated the Zacatecan militia and took almost 3,000 prisoners. He allowed his army to loot Zacatecas City for forty-eight hours. After conquering Zacatecas, he planned to move on to Coahuila y Tejas to quell the rebellion there, which was being supported by settlers from the United States.
