During the Spanish colonization of California, they had several goals in mind. Firstly, they aimed to expand their territory and secure the land from potential foreign threats, such as the British and Russians. They also sought to convert the native people to Christianity through the establishment of missions, which served as religious and educational centers. Additionally, the Spanish hoped to benefit economically from the rich natural resources found in California, such as fertile land, timber, and precious metals. Overall, their objectives were rooted in territorial expansion, religious influence, and economic gain.
