The Baltimore Police Department (BPD) is the municipal police department of the city of Baltimore, Maryland. Dating back to 1784, the BPD, consisting of 2,935 employees in 2020, is organized into nine districts covering 80.9 square miles (210 km2) of land and 11.1 square miles (29 km2) of waterways. The department is sometimes referred to as the Baltimore City Police Department to distinguish it from the Baltimore County Police Department.
History
Foundation to the 1840s
The first attempt to establish professional policing in Baltimore was in 1784, nearly 60 years after the founding of the colonial town and eight years after United States independence. The city authorized a night watch and a force of day constables to enforce town laws, particularly catching runaway slaves. Nightwatchman George Workner was the first law enforcement officer to be killed in the city; he was stabbed during an escape attempt by nine inmates at Baltimore City Jail on March 14, 1808.
The department was founded in its current form (with uniforms and firearms) in 1853 by the Maryland state legislature "to provide for a better security for life and property in the City of Baltimore". The state did not give the city the power to run its own police affairs. The early decades of the department were marked by internal political conflict over split loyalties. In 1857 the police were reorganized by Mayor Thomas Swann and new men were recruited; many came from Know Nothing gangs in the city and maintained loyalties to former leaders.
