Why Spain Settled Alta California
Key Idea
For over 200 years after Cabrillo, Spain explored the coast but left it mostly empty. But by the late 1700s, Spain grew worried that Russian fur traders or the British would take over California.
To protect its land, Spain decided to build settlements. In 1769, an expedition led by Gaspar de Portolá and Father Junípero Serra traveled north. In San Diego, Father Serra established the first mission in Alta California. This marked the beginning of permanent Spanish settlement.
