Then a massive peasant uprising began, led by a renegade priest, Padre Hidalgo, and supported by the Creoles because it was aimed at the Peninsulares, even though they weren't actually the ones who supported Spain. This was further complicated by the fact that to the mestizo peasants led by Hidalgo, Creoles and Peninsulares looked and acted basically identical. They were both white and imperious, so the peasants often attacked the Creoles, who were technically on their side in trying to overthrow the ruling Peninsulares. 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.
