What group of people lost their land in California during the gold rush

The Natives lost their land.

The disruptions of the Gold Rush proved devastating for California's native groups, already in demographic decline due to Spanish and Mexican intrusion. The state's native population plummeted from about 150,000 in 1848 to 30,000 just 12 years later. As foreigners methodically mined, hunted, and logged native groups' most remote hiding places, natives began raiding mining camps for subsistence. This led to cycles of violence as American miners - supported by the state government - organized war parties and sometimes slaughtered entire native groups.

The Act for the Government and Protection of Indians, passed by the state legislature in 1850, denied native Californians the right to testify in court and allowed white Americans and Californios to keep natives as indentured servants. "I do not like the white man because he is a liar and a thief," Isidora Filomena de Solano, a Patwin-speaking woman from the Bay Area, told an interviewer in 1874. She echoed the sentiments of many native Californians struggling to preserve traditional ways in the midst of holocaust.
