History
Founded in 1852
An old deed may name a county that no longer exists, or a boundary that has since moved.
Valencia County was created as one of seven original New Mexico counties under Kearny's Code of Laws in 1846 for the occupied Mexican territory. The county was named after Valencia. In 1852, Valencia was redefined when Socorro and Bernalillo counties were created, and the county lost territory to Arizona Territory when it was established in 1863. Valencia gained and lost territory multiple times through the 19th and early 20th centuries, including gains from Bernalillo County and Lincoln County.
