The Spanish missions in California comprise a series of 21 religious outposts or missions established between 1769 and 1833 in today's U.S. State of California. Founded by Catholic priests of the Franciscan order to evangelize the Native Americans, the missions led to the creation of the New Spain province of Alta California and were part of the expansion of the Spanish Empire into the most northern and western parts of Spanish North America.
Following long-term secular and religious policy of Spain in Spanish America, the missionaries forced the native Californians to live in settlements called reductions, disrupting their traditional way of life. The missionaries introduced European fruits, vegetables, cattle, horses, ranching, and technology. The missions have been accused by critics, then and now, of various abuses and oppression. In the end, the missions had mixed results in their objectives: to convert, educate, and transform the natives into Spanish colonial citizens.
By 1810, Spain's king had been imprisoned by the French, and financing for military payroll and missions in California ceased. In 1821, Mexico achieved independence from Spain, although Mexico did not actually send a governor to California until 1824, and only a portion of payroll was ever reinstated (ibid.). The 21,000 Mission Indians produced hide and tallow and wool and textiles at this time, and the leather products were exported to Boston, South America, and Asia which kept the colonial economy going between 1810 and 1830, but tended to give British or New England merchant captains importance. The missions began to lose control over land in the 1820s, as unpaid military men unofficially encroached, but officially missions maintained authority over native neophytes and control of land holdings until the 1830s. At the peak of its development in 1832, the coastal mission system controlled an area equal to approximately one-sixth of Alta California. The Alta California government secularized the missions after the passage of the Mexican secularization act of 1833. This divided the mission lands into land grants, in effect legitimizing and completing the transfer of Indian congregation lands to military commanders and their most loyal men; these became many of the Ranchos of California.
