Dodoma (lit. 'It has sunk' in Gogo), officially Dodoma City (Jiji Kuu la Dodoma, in Swahili), is the capital city of Tanzania. With a population of 765,179, it is also the administrative capital of both Dodoma Municipal Council and the entire Dodoma Region. In July 2024, Dodoma officially surpassed Arusha to become the third largest city in Tanzania on both infrastructure and population measures.In 1974, the Tanzanian government announced that Tanzania's national capital would be moved from Dar es Salaam to Dodoma for social and economic reasons and to centralise the capital within the country. It became the official capital in 1996.
Much of Dodoma's initial design did not come to fruition until the 21st century. In May 2023, the national government under President Samia Suluhu unveiled the new State House in Dodoma in a historic event stamping the relocation of government duties to the city. As a result, Dar es Salaam has remained the commercial and maritime capital of Tanzania, while also retaining the state house Ikulu and a number of government functions.
