What lead to the end of the mission system?

The mission system in California, established by Spanish colonizers to convert and control Indigenous populations, began to decline in the early 19th century due to a combination of factors. The secularization of the missions in the 1830s, driven by Mexican government policies that aimed to reduce the influence of the Catholic Church, significantly diminished their power and resources. Additionally, increasing tensions and conflicts with Native Americans, coupled with the influx of settlers during the California Gold Rush, further undermined the mission's original objectives. Ultimately, these changes led to the disbanding of the mission system and the transformation of the region's social and economic landscape.
