Youth

Born in the Val-de-Cães neighbourhood in Belém on June 2, 1888, to Major Marcelino Cardoso Barata and Gabrina de Magalhães Barata, Joaquim spent most of his childhood in the city of Monte Alegre, Pará, enlisted in the military in 1904 and graduated from the Escola Militar do Realengo on Rio de Janeiro in 1911 to become an Aspirant in the Brazilian Army.^[1]

After graduation, Magalhães Barata was sent to the 47th Hunter Battalion in his hometown of Belém, where he was promoted to second lieutenant in 1915 and given command of the garrison in the city of Oiapoque in the border with French Guiana. In 1920, he was promoted to first lieutenant and sent back to Rio de Janeiro.^[1]

Tenentist Revolutionary

After the initial revolutionary movements in 1922, Magalhães Barata joined the Tenentist Movement, where on December 24, 1923, he was given orders to move to the state of Paraná where on 28 December he would apprehend the minister of war Fernando Setembrino de Carvalho, an act which would serve as the spark to lead the rise of rebel forces in the state.^[1]

However, the plan was revealed and Magalhães Barata was jailed in the 25th on São Paulo, from where he was sent to Manaus to join the 27th Hunter Battalion. On June 23, 1924, in command of the battalion, he and other tenentists took over the government of the state of Amazonas to install a government junta led by his fellow revolutionary Alfredo Augusto Ribeiro Júnior.^[1]

The tenentists would expand into Pará and take control of the fortress of Óbidos in an attempt to assume control of the Amazon River, however, federal troops led by General João de Deus Mena Barreto took back the fortress in August 20, after fighting with forces led by Magalhães Barata.^[1]

Jailed and sent to Belém together with some of his fellow revolutionaries, Magalhães Barata escaped prison and sought refuge in Uruguay, from where he would only come back in August 1930 when using a fake identity he returned to Belém and attempted to articulate a revolutionary movement in the region, however despite his disguise, he was once again jailed and sent to Rio de Janeiro.^[1]

Vargas Era

After the Brazilian Revolution of 1930, Magalhães Barata was released from prison and returned to Belém, this time as Federal Interventor for the Vargas Government where he was met with great popular support, three days after taking over as interventor, he was promoted to captain and once again to major in August 1931.^[1]

In December 1931, Magalhães Barata founded the Liberal Party of Pará, which reunited the revolutionary elements in the state and supported the politics of Getúlio Vargas, being affiliated with his National Civic Union. On the elections of 1933, the Liberal Party elected all the representatives of the state of Pará to the National Constitutionalist Assembly.^[1]

By 1934 however, the party's influence decreased as the opposition united under the Paraense United Front, and in the elections held in October of that year, they only elected seven of the nine Federal Deputies and 21 of the 30 Deputies in the state's Constitutional Assembly. In 1935 the assemble attempted to elect Mário Chermont instead of Magalhães Barata after seven deputies of his Liberal Party broke off with him, this led to police force against the deputies to stop the voting, after which Magalhães Barata was elected governor of the state by the deputies which had been able to vote.^[1][2]

His election would not be upheld, as a habeas corpus impetrated to the Regional Electoral Tribunal put in question the legality of the elections, leading to a renewed federal intervention in the state led by Interventor Roberto Carlos Vasco Carneiro de Mendonça on April 12, 1935, and after efforts to pacify the region, new elections were held on April 29, 1935, where José Carneiro da Gama Malcher was elected governor of Pará.^[1][2]

In January 1936, Magalhães Barata returned to active military service, assuming command of the 6th Hunter Battalion in Ipameri , in May of the same year, was promoted to lieutenant colonel and in September 1939 was promoted to colonel remaining in military service until February 8, 1943, when he was once again nominated Federal Interventor in the State of Pará where he remained until the end of the Vargas Government.^[1][2]

Politician

In 1945, the last year of the Vargas Government, Magalhães Barata was one of the founding members of the Social Democratic Party, even founding its branch on the state of Pará, preparing to participate in the state elections on December 2, 1945.^[1]

However, the state elections were suspended due to the deposition of Vargas, but the federal elections were held and Magalhães Barata supported the election Eurico Gaspar Dutra for the presidency and candidated himself to the Senate, both won.^[1][3]

As a senator, Magalhães Barata was a member of the Constitutional Commission, the Commission of the Armed Forces and the Subcomission of National Security, in 1947, he supported Major Luís Geolás de Moura Carvalho in the state elections for the state of Pará, which Moura Carvalho won, defeating General Alexandre Zacarias de Assunção. In 1950, Magalhães Barata attempted to become governor of Pará but was defeated by the same General Alexandre Zacarias de Assunção by 555 votes.^[1]

In 1954, Magalhães Barata got reelected as senator and in 1955 with the support of Juscelino Kubitschek he defeated Epílogo de Campos by 1743 votes and was elected governor of Pará, a position which he held until his death on May 29, 1959, at 70 years of age.^[1][3][4]
