In the early to mid-1830s, the political situation in Mexico underwent much upheaval. Federalists wished to delegate many powers to the individual Mexican states, while centralists wished to consolidate power at the national level. In 1835, several interior Mexican states, angry at the increasingly dictatorial policies of Mexican President Antonio López de Santa Anna, took up arms against the Mexican government. Texians launched their own armed rebellion, known as the Texas Revolution, in October 1835. Over the next two months, Texians successfully removed all Mexican troops from the region. Their actions infuriated Mexican president Antonio Lopez de Santa Anna, who immediately began preparations to invade Texas. Most of the Navarro family supported the Texian cause. An exception was Juana's father, who joined Santa Anna's new Army of Operations in Texas as an officer. Although he remained loyal to Mexico, José Ángel Navarro had been very vocal in his disagreement with Santa Anna's overthrow of the 1824 Constitution of Mexico.
