Even though it had tens of thousands of supporters, this first peasant uprising petered out. But a second peasant revolt, led by another priest, Father Morales, was much more revolutionary. In 1813, he declared independence, and the revolt lasted until his death in 1815. But since he was a mestizo, he didn't gain much Creole support, so revolutionary fervor in Mexico began to fade... until 1820, when Spain, which was now under the rule of a Spanish rather than a French king, had a real liberal revolution with a new constitution that limited the power of the church. Thanks, Thought Bubble. So in the wake of Spain's liberalizing movements, the Mexican elites who had previously supported Spain switched sides and made common cause with the Creoles in the hopes that they could somehow hold on to their privileges. And pushing for independence together, things went very well.
