Birmingham ( BUR-ming-ham) is a city located in the north central region of the U.S. state of Alabama. With an estimated 2017 population of 210,710, it is the most populous city in Alabama. Birmingham is the seat of Jefferson County, Alabama's most populous and fifth largest county. As of 2017, the Birmingham-Hoover Metropolitan Statistical Area had a population of 1,149,807, making it the most populous in Alabama and 49th-most populous in the United States. Birmingham serves as an important regional hub and is associated with the Deep South, Piedmont, and Appalachian regions of the nation.
Birmingham was founded in 1871, during the post-Civil War Reconstruction era, through the merger of three pre-existing farm towns, most notably Elyton. The new city was named for Birmingham, England, the UK's second largest city and, at the time, a major industrial city. The Alabama city annexed smaller neighbors and developed as an industrial center, based on mining, the new iron and steel industry, and rail transport. Most of the original settlers who founded Birmingham were of English ancestry. The city was developed as a place where cheap, non-unionized immigrant labor (primarily Irish and Italian), along with African-American labor from rural Alabama, could be employed in the city's steel mills and blast furnaces, giving it a competitive advantage over unionized industrial cities in the Midwest and Northeast.
From its founding through the end of the 1960s, Birmingham was a primary industrial center of the southern United States.
