The Montgomery Metropolitan Statistical Area had a 2010 estimated population of 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 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 selected as the first capital of the Confederate States of America, until the seat of government moved to Richmond, Virginia, in May of that year. During the mid-20th century, Montgomery was a major center of events and protests in the Civil Rights Movement, including the Montgomery Bus Boycott and the Selma to Montgomery marches.
