Montgomery is the capital city of the U.S. state of Alabama and the county seat of Montgomery County. Named for Richard Montgomery, it stands beside the Alabama River, on the coastal Plain of the Gulf of Mexico. In the 2010 Census, Montgomery's population was 205,764. According to the US estimated census of 2019, it is the third most populous city in Alabama, after Birmingham and Huntsville, and is the 118th most populous in the United States. The Montgomery Metropolitan Statistical Area's population in 2010 was estimated at 374,536; it is the fourth largest in the state and 136th among United States metropolitan areas.
The city was incorporated in 1819 as a merger of two towns situated along the Alabama River. It became the state capital in 1846, representing the shift of power to the south-central area of Alabama with the growth of cotton as a commodity crop of the Black Belt and the rise of Mobile as a mercantile port on the Gulf Coast. In February 1861, Montgomery was chosen the first capital of the Confederate States of America, which it remained until the Confederate seat of government moved to Richmond, Virginia, in May of that year.
