Spanish Explorers Bring New Diseases and Conflict

This Grade 3 history skill from California myWorld Interactive explains how Spanish explorers unintentionally brought new diseases like measles and smallpox that devastated California Indian populations who had no immunity, covered in Chapter 3: Changes in California Over Time. Students learn how European contact caused a catastrophic population decline in Native communities.

Key Concepts

When Spanish explorers and soldiers first arrived on the coast of California, they unknowingly carried germs that were new to the region. California Indian tribes had no natural protection against European illnesses. As a result, the introduction of a new disease could have a devastating impact on a village or an entire community.

Illnesses like measles and smallpox spread quickly, leading to a dramatic decline in the Native American population. This loss of life weakened tribes' social structures and their ability to resist the newcomers. This period of initial contact and conflict set the stage for the establishment of Spanish missions, which would further transform the lives of California's native peoples.
