By the time Spanish explorers arrived in the 16th century, the dominant group were the Tongva people. They had at least three major settlements within the present-day city boundaries. Tevaaxa'anga was an inland settlement near the Los Angeles River, while Ahwaanga and Povuu'nga were coastal villages. Along with other Tongva villages, they were forced to relocate in the mid-19th century due to missionization, political change, and a drastic drop in population from exposure to European diseases.
