Baltimore

Baltimore is the most populous city in the U.S. state of Maryland, with a recorded population of 585,708 at the 2020 census. Serving as a vital economic engine through historical shifts, the city functioned as the second-leading port of entry for immigrants arriving in the United States via its Inner Harbor, second only to New York's Ellis Island.

Through its expansive maritime and rail networks, the city transformed into a major manufacturing and transportation hub, linking producers in the Midwest and Appalachia directly to global trade via the nation's oldest railroad, the Baltimore and Ohio Railroad, built in 1830. Following a later decline in heavy industry and a restructuring of the rail sector, Baltimore successfully transitioned into a service-oriented economy. Today, major economic drivers and top employers include Johns Hopkins Hospital and University, anchoring the modern workforce in a municipality officially designated as a Gamma− world city by the Globalization and World Cities Research Network.

Baltimore is the most populous city in the U.S. state of Maryland and functions as an independent city situated within the Central Maryland region. The municipality spans an elevation of 10 meters and is recorded at coordinates 39.29038 latitude and -76.61219 longitude.

Originally utilized as a hunting ground by Paleo-Indians and later by the Susquehannock in the early 1600s, the land transformed through the establishment of the Port of Baltimore in 1706 by people from the Province of Maryland to support the European tobacco trade. The Town of Baltimore was established in 1729. During the American Revolutionary War, the Second Continental Congress briefly relocated its deliberations to the Henry Fite House from December 1776 to February 1777 before Philadelphia was captured by British troops, allowing Baltimore to function briefly as the nation's capital. The British bombardment of Fort McHenry during the War of 1812 inspired Francis Scott Key to write the poem that became the U.S. national anthem in 1931.

Cultural exchange and industrial growth accelerated in the 19th century. In 1830, the Baltimore and Ohio Railroad was constructed as the nation's oldest railroad, connecting producers in the Midwest and Appalachia to the city port. Baltimore's Inner Harbor developed as the second-leading port of entry for immigrants to the United States after New York's Ellis Island, establishing the community as a major manufacturing center. The city also pioneered gas lighting in 1816 and established the world's first dental college, the Baltimore College of Dental Surgery, in 1840, alongside participating in the world's first telegraph line between Baltimore and Washington, D.C. in 1844.

Today, the city hosts historic areas such as Fells Point, Federal Hill, and Mount Vernon, featuring 66 National Register Historic Districts and 33 local historic districts. The area maintains a population recorded at 585,708 during the 2020 census and is recognized as a Gamma minus world city by the Globalization and World Cities Research Network.
