Why California Missions Ceased Operations

Four major factors ended the mission era:

1. Indigenous Population Collapse: European diseases (smallpox, measles) decimated native communities, destroying the missions' labor force.
2. Secularization (1833): Mexican government passed Secularization Acts, stripping Church control, confiscating mission lands/properties for private distribution.
3. Political Shift: Post-1821 Mexican independence brought anti-clerical policies reducing Church power.
4. Gold Rush (1849): Population explosion and gold fever drew workers away, depleting mission resources.

These forces caused the missions to decline and cease functioning as religious-economic institutions.
