The Municipality of Montevideo was first created by a legal act of 18 December 1908. The municipality's first mayor (1909–1911) was Daniel Muñoz. Municipalities were abolished by the Uruguayan Constitution of 1918, effectively restored during the 1933 military coup of Gabriel Terra, and formally restored by the 1934 Constitution. The 1952 Constitution again decided to abolish the municipalities; it came into effect in February 1955. Municipalities were replaced by departmental councils, which consisted of a collegiate executive board with 7 members from Montevideo and 5 from the interior region. However, municipalities were revived under the 1967 Constitution and have operated continuously since that time.
