History

Formed in 1864 from Cache County

An old deed may name a county that no longer exists, or a boundary that has since moved.

Originally named Richland when created by Utah Territory from Cache County on January 16, 1864, the county was fully organized by May 5 of that year. Richland was renamed Rich on January 29, 1868. In July 1868, Rich lost territory to the newly created Wyoming Territory and was eliminated from present-day Wyoming. Rich became a county in the state of Utah on January 4, 1896.
