Mobile County was created by proclamation of Gov. Holmes of the Mississippi Territory on 1812 Dec. 18. Mobile County is located in the southwestern corner of the State of Alabama, and is bordered by the State of Mississippi on the west, Washington County on the north, Baldwin County and Mobile Bay on the east, and the Gulf of Mexico on the south. It encompasses 1, 238 square miles. Both the city and the county derive their name from Fort Louis de la Mobile, a French fortification erected near Mount Vernon in 1702. The word Mobile is believed to come from a Choctaw Indian word for "paddlers." The area was occupied by the French from 1702-63, by the British from 1763-80, and by the Spanish from 1780-1813.
Mobile County, the second largest county in the state, is a county rich in southern charm and hospitality.
