Doing some research I was reminded of this:
"Up to 16,000 Native Americans were murdered in cold blood after California became a state.
"By demonstrating that the state would not punish Indian killers, but instead reward them,”writes historian Benjamin Madley, “militia expeditions helped inspire vigilantes to kill at least 6,460 California Indians between 1846 and 1873.” The U.S Army also joined in the killing, Madley notes, killing at least 1,600 native Californians." https://www.history.com/news/californias-little-known-genocide
