History

Formed in 1816 from Monroe County

An old deed may name a county that no longer exists, or a boundary that has since moved.

Montgomery County was created in 1816 from Monroe County by Mississippi Territory. It was named after Lemuel Purnell Montgomery. In 1817, Montgomery County became part of Alabama Territory when Alabama Territory was created from Mississippi Territory. Over the following years, Montgomery County lost territory to the creation of numerous surrounding counties, including Blount, Franklin, Lawrence, Tuscaloosa, Cahawba (now Bibb), Shelby, Dallas, Autauga, Wilcox, and Pike, though it later regained territory from Pike in 1824.
