Washington–Baltimore combined statistical area in the context of "Central Maryland"

Baltimore is the most populous city in the U.S. state of Maryland. It is the 30th-most populous U.S. city with a population of 585,708 at the 2020 census and estimated at 568,271 in 2024, while the Baltimore metropolitan area at 2.86 million residents is the 22nd-largest metropolitan area in the nation. The city is also part of the Washington–Baltimore combined statistical area, which had a population of 9.97 million in 2020. Baltimore was designated as an independent city by the Constitution of Maryland in 1851. Though not located under the jurisdiction of any county in the state, it forms part of the Central Maryland region together with the surrounding county that shares its name.

The land that is present-day Baltimore was once used as hunting ground by Paleo-Indians. In the early 1600s, the Susquehannock began to hunt there. People from the Province of Maryland established the Port of Baltimore in 1706 to support the tobacco trade with Europe and established the Town of Baltimore in 1729. During the American Revolutionary War, the Second Continental Congress briefly moved its deliberations to the Henry Fite House from December 1776 to February 1777 prior to the capture of Philadelphia to British troops, which permitted Baltimore to serve briefly as the nation's capital before it returned to Philadelphia. The Battle of Baltimore was pivotal during the War of 1812, culminating in the British bombardment of Fort McHenry, during which Francis Scott Key wrote a poem that became "The Star-Spangled Banner", which was designated as the national anthem in 1931. During the Pratt Street Riot of 1861, the city was the site of some of the earliest violence associated with the American Civil War.

Culpeper (formerly Culpeper Courthouse, earlier Fairfax) is an incorporated town in Culpeper County, Virginia, United States. It is the county seat and part of the Washington–Baltimore combined statistical area. At the 2020 United States Census, the population was 20,062, an increase from 16,379 in 2010. Its growth has been influenced by the town's location along U.S. Route 15, U.S. Route 29, and U.S. Route 522, as well as its rail and bus connections and proximity to the Washington metropolitan area.

The town was laid out in 1749 by a young George Washington while working as a surveyor for Lord Fairfax, and formally established in 1759 by the Virginia House of Burgesses under the name Fairfax. During the American Revolutionary War, the Culpeper Minutemen militia organized here in 1775. In the American Civil War, Culpeper was occupied by both Union and Confederate forces due to its strategic position along the Orange and Alexandria Railroad, and the surrounding county saw engagements including the Battle of Brandy Station, the largest cavalry battle of the war.
