History of Solano County

Solano County was one of the very first counties in California. It was created in 1850 when California officially became a state.

The county was named after Chief Solano. He was a leader of the Suisun people, a Native American tribe from this area. Chief Solano was a close friend of General Mariano Guadalupe Vallejo, who asked for the county to be named after him. Chief Solano was also known as Sem-Yeto, which means "brave or fierce hand." He was given the Spanish name Francisco Solano when he was baptized. This name came from a Spanish Franciscan missionary named Father Francisco Solano.

Travis Air Force Base, an important military base, is located just east of Fairfield. In recent years, a company called California Forever bought a lot of land in the county. They plan to build a new city there.
