Alabama legislators created Mobile County - one of the nation’s fastest growing southern counties - in 1812. The county's colorful history began with the establishment of Native American villages, followed by the arrival of European explorers in 1509. The first European settlement was established in 1702, with the official designation as a county on December 18, 1812. In 1819, Mobile County became a part of the state of Alabama.

Three County Commissioners are elected from districts to concurrent four year terms. Their mission is to provide for the safety and welfare of all citizens through the delivery of essential public services. Mobile County is primarily an administrative and executive unit of government operating by laws set by the Alabama Legislature.

Other elected county officials include the Sheriff, License Commissioner, Revenue Commissioner, Probate Judge, and the Treasurer. These officials are independent of the County Commission's authority. The Commission is only responsible for the budgets of each county official office.
