The Wiyot Massacre occurred in 1860 on Indian Island, California, where members of the Wiyot tribe were attacked by white settlers. During a ceremonial gathering, the settlers killed around 100 Wiyot people, including women and children, in a brutal act of violence aimed at seizing their land. This tragic event is part of a broader history of conflict between Native American tribes and European settlers in the United States. The massacre led to the near destruction of the Wiyot culture and community, highlighting the devastating impact of colonization on indigenous populations.
