Mariposa

Mariposa (/ˌmærɪˈpoʊzə, -sə/ ; Spanish for "Butterfly") is an unincorporated community and census-designated place (CDP) in and the county seat of Mariposa County, California, United States. The population was 1,526 at the 2020 census. Named for the monarch butterflies that overwinter there, the community's history is deeply intertwined with the California Gold Rush of the 19th century.

During the California Gold Rush, prospectors flocked to Mariposa for its rich mineral resources in streams and underground veins. Among them was John C. Frémont, Mariposa's most prominent resident, who leveraged his extensive mineral claims to achieve national prominence. He became the first U.S. senator from California and the inaugural Republican presidential candidate, significantly impacting both Mariposa and American politics during the 19th century's period of expansion.
