Bernalillo County, New Mexico: History
Bernalillo County was one of seven partidos established during Mexican rule; in 1852, within two years of the creation of the New Mexico Territory, Bernalillo became one of that territory's nine original counties. Bernalillo County was named for the town of Bernalillo, which is no longer part of the county. The towns of Los Ranchos de Albuquerque and Bernalillo were previously the county seats, but the capital was finally established in Albuquerque in 1883. In 1876, it absorbed Santa Ana County.
In 1906, years after the Land Revision Act of 1891 provided for the setting aside of forest reserves, the parts of Bernalillo County currently known as Cibola National Forest were established as reserves.
USS LST-306, a World War II tank landing ship that participated in the Allied invasion of Italy, was renamed as USS Bernalillo County in 1955. Sandia Mountain Wilderness was created in 1978 and the Petroglyph National Monument was established in June 1990.
