with the participation of the district of Lajão, which became the municipality of Conselheiro Pena. Eleven years after the creation of the town, the Governor of the State, José de Magalhães Pinto, issued a document (Decree No. 1,058), creating the Municipality of Mantena. On January 4, 1944, the first mayor, José Fernandes Filho (Fernandinho) was appointed by the Governor. On December 30, 1944, by Decree 1291 was installed the Comarca de Mantena, being its first Osvaldino Judge of Paula Salazar.

On December 9, 1963, the Official Gazette of the State of Minas Gerais published Resolution 569, Governor Magalhães Pinto. In it, along the "Law 2084 of the State of Espírito Santo", was defined the dividing line of the municipality, between the two states north of the Rio Doce, with the delimitations that it has today. At that time the district composition of the municipality was as follows: Headquarters, São João do Manteninha, Itabirinha. Santo Agostinho de Minas, Água Doce do Mantena and Barra do Ariranha.
