. On May 2, 1893, seventy percent of voters approved the formation of Riverside County. Voters chose the city of Riverside as the county seat, also by a large margin. Riverside County was officially formed on May 9, 1893, when the Board of Commissioners filed the final canvass of the votes.
Riverside county was a major focal point of the Civil Rights Movements in the US, especially the African-American sections of Riverside and heavily Mexican-American communities of the Coachella Valley visited by Cesar Chavez of the farm labor union struggle.
Riverside county has also been a focus of modern Native AmericanGaming enterprises. In the early 1980s, the county government attempted to shut down small bingo halls operated by the Morongo Band of Cahuilla Mission Indians and the Cabazon Band of Mission Indians. The tribes joined forces and fought the county all the way to the U.S. Supreme Court, which ruled in the tribes' favor on February 25, 1987. In turn, Congress enacted the Indian Gaming Regulatory Act in 1988 to establish a legal framework for the relationship between Indian gaming and state governments. Naturally, both tribes now operate large casinos in the county: the Morongo Casino, Resort & Spa and the Fantasy Springs Resort Casino adjacent to Spotlight 29 Casino.
