Starting with the onset of the Mexican War of Independence in 1810, this support largely disappeared, and the missions and their converts were left on their own. By 1827, the Mexican government passed the General Law of Expulsion, which exiled Spanish-born people, decimating the clergy in California. Some of the missions were then nationalized by the Mexican government and sold off. It was not until after statehood that the US Supreme Court restored some missions to the orders that owned them.
