The area on which Maputo stands was first settled as a fishing village by ancient Tsonga people. It was soon named Lourenço Marques, after the navigator of the same name who explored the area in 1544. The modern city traces its origins to a Portuguese fort established on the site in 1781. A town grew around the fort starting around 1850, and in 1877 it was elevated to city status. In 1898, the colony of Portuguese Mozambique relocated its capital there. In the late 19th and early 20th centuries, Lourenço Marques grew both in population and economic development as a port city. Upon Mozambican independence in 1975, the city became the national capital and was renamed Maputo. During the Mozambican Civil War, the city's economy was devastated. When the war ended, the FRELIMO government launched a program to revive the city's economy, and to clean up the city by forcibly removing criminals, squatters, and undocumented residents.
