The activist movement Black Lives Matter was initially formed by Opal Tometi, Alicia Garza, and Patrisse Kahn-Cullors as a hashtag to campaign against racism and police brutality against African Americans in the United States. The movement contributed to a revitalization and re-examining of the black feminist movement. While the deaths of black men played a major part in the Black Lives Matter movement, Rekia Boyd, Michelle Cusseaux, Tanisha Anderson, Shelly Frey, Yvette Smith, Eleanor Bumpurs, Sandra Bland, and other women were also killed or assaulted by police officers.
