The Brazilian Navy is the naval service branch of the Brazilian Armed Forces, responsible for conducting naval operations.
The Brazilian Naval Revolts, or the Revoltas da Armada, were armed mutinies promoted mainly by admirals Custódio José de Melo and Saldanha da Gama and their fleet of rebel Brazilian navy ships against the claimed unconstitutional staying in power of president Floriano Peixoto.
São Paulo was a dreadnought battleship of the Brazilian Navy. It was the second of two ships in the Minas Geraes class, and was named after the state and city of São Paulo.
The Platine War was fought between the Argentine Confederation and an alliance consisting of the Empire of Brazil, Uruguay, and the Argentine provinces of Entre Ríos and Corrientes, with the participation of the Republic of Paraguay as Brazil's co-belligerent and ally. The war was part of a decades-long dispute between Argentina and Brazil for influence over Uruguay and Paraguay, and hegemony over the Platine region. The conflict took place in Uruguay and northeastern Argentina, and on the Río de la Plata. Uruguay's internal troubles, including the longrunning Uruguayan Civil War, were heavily influential factors leading to the Platine War.
Minas Geraes, spelled Minas Gerais in some sources, was a dreadnought battleship of the Brazilian Navy. Named in honor of the state of Minas Gerais, the ship was laid down in April 1907 as the lead ship of its class, making the country the third to have a dreadnought under construction and igniting a naval arms race between Brazil, Argentina, and Chile.
The Armed Forces of the Empire of Brazil were the overall unified military forces of the Empire of Brazil. The Brazilian military was first formed by Emperor Dom Pedro I to defend the new nation against the Portuguese in the Brazilian War of Independence. The Army and Armada were commissioned in 1822 with the objective of defeating and expelling the Portuguese troops from Brazilian soil.
During World War I (1914–1918), Brazil initially adopted a neutral position, in accordance with the Hague Convention, in an attempt to maintain markets for its export products, mainly coffee, latex and industrially manufactured items. However, following the repeated sinking of Brazilian merchant ships by German submarines, President Venceslau Brás declared war against the Central Powers in 1917. Brazil was the only country in Latin America to be directly involved in the war. The major participation was the Brazilian Navy's patrol of areas of the Atlantic Ocean.
Pedro Max Fernando Frontin was an Admiral from the Brazilian Navy. He fought alongside the Triple Entente during World War I.
The siege of Paysandú began on 3 December 1864, during the Uruguayan War, when Brazilian forces and Colorado forces attempted to capture the city of Paysandú in Uruguay from its Uruguayan Army defenders. The siege ended on 2 January 1865, when the Brazilian and Colorado forces conquered the town.
The Battle of 4 May was fought in open sea near Salvador, Bahia, on 4 May 1823, between the Imperial Brazilian Navy, under the command of British admiral Thomas Cochrane, and the Portuguese Navy during the Brazilian War of Independence.
Bahia was the lead ship of a two-vessel class of cruisers built for Brazil by the British company Armstrong Whitworth. Crewmen mutinied in November 1910 aboard Bahia, Deodoro, Minas Geraes, and São Paulo, beginning the four-day Revolta da Chibata. Brazil's capital city of Rio de Janeiro was held hostage by the possibility of a naval bombardment, leading the government to give in to the rebel demands which included the abolition of flogging in the navy. During the First World War, Bahia and its sister ship Rio Grande do Sul were assigned to the Divisão Naval em Operações de Guerra, the Brazilian Navy's main contribution in that conflict. The squadron was based in Sierra Leone and Dakar and escorted convoys through an area believed to be heavily patrolled by U-boats.
Two Minas Geraes-class battleships were built for the Brazilian Navy in the early twentieth century. Named Minas Geraes and São Paulo, these "dreadnought" warships were intended to be Brazil's first step towards becoming an international power, and they consequently initiated a South American naval arms race.
A naval arms race among Argentina, Brazil and Chile—the wealthiest and most powerful countries in South America—began in the early twentieth century when the Brazilian government ordered three dreadnoughts, formidable battleships whose capabilities far outstripped older vessels in the world's navies.
The Imperial Brazilian Navy was the navy created at the time of the independence of the Empire of Brazil from the United Kingdom of Portugal, Brazil and the Algarves. It existed between 1822 and 1889 during the vacancy of the constitutional monarchy.
The Imperial Brazilian Army was the name given to the land force of the Empire of Brazil. The Brazilian Army was formed after the independence of the country from Portugal in 1822 and reformed in 1889, after the republican coup d'état that created the First Brazilian Republic, a dictatorship headed by the army.
The steam frigate Amazonas was a frigate-type warship that served in the Imperial Brazilian Navy and, for a short period, in the Brazilian Navy after the Proclamation of the Republic in 1889. The frigate was built in the Thomas Wilson Sons & Co. shipyards in Birkenhead and Liverpool, England; it was launched in August 1851. The purchase of this vessel was part of an effort by the Empire of Brazil to obtain more modern ships, due to the country's lag with some foreign powers. Amazonas was commissioned in 1852.
Dom Afonso was a steam frigate that served the Imperial Brazilian Navy, being the first steamship to serve in this navy. It was built in England under the supervision of chief of squad John Pascoe Grenfell and was named Dom Afonso in honor of Afonso, Prince Imperial of Brazil, son of emperor Pedro II of Brazil and empress Teresa Cristina.
Tymbira was a torpedo cruiser operated by the Brazilian Navy, belonging to the Tupi-class along with Tamoio and Tupi. During the First World War it patrolled the Brazilian coast. It was dismissed from service on 30 November 1917.
The Brazilian ironclad Colombo was a Cabral-class armored corvette-type ironclad operated by the Imperial Brazilian Navy between 1866 and 1875. The vessel was built in the shipyard in Greenwich, England, by the British company J. and G. Rennie, along with her sister ship Cabral. It was launched in 1865 being commissioned on 4 July 1866. The battleship was entirely made of iron, displacing 1,069 tons. It had two steam engines that developed up to 750 HP of power, propelling the vessel at about 20 km/h. Its structure comprised a double casemate with eight gunports. The Brazilian navy had great difficulties with this ship, which was hard to navigate and, due to the casemate's model, had an unprotected section, which was vulnerable to diving projectiles.
Laurindo Pitta is a museum ship and former tugboat of the Brazilian Navy, subordinated to the Directorate of Historical Heritage and Documentation of the Navy (DHHDN). She is the oldest boat of the navy still in service, being built by the British shipyard Vickers, Sons & Maxim, Ltd, in 1910. The tugboat is 39 meters long and displaced up to 514 tons in weight. She belonged to the Naval War Operations Division, part of the Brazilian squadron sent to patrol the northeastern African coast during World War I. In World War II, she participated in helping to defend the port of Rio de Janeiro. Laurindo Pitta was decommissioned on 16 September 1959, but was still used by the Brazilian Navy until the 1990s.
