The Brazilian Armed Forces are the unified military forces of the Federative Republic of Brazil. Consisting of three service branches, it comprises the Brazilian Army, the Brazilian Navy and the Brazilian Air Force.
State police, provincial police or regional police are a type of sub-national territorial police force found in nations organized as federations, typically in North America, South Asia, and Oceania. These forces typically have jurisdiction over the relevant sub-national jurisdiction, and may cooperate in law enforcement activities with municipal or national police where either exist.
The Brazilian Army is the branch of the Brazilian Armed Forces responsible, externally, for defending the country in eminently terrestrial operations and, internally, for guaranteeing law, order and the constitutional branches, subordinating itself, in the Federal Government's structure, to the Ministry of Defense, alongside the Brazilian Navy and Air Force. The Military Police and Military Firefighters Corps are legally designated as reserve and auxiliary forces to the army. Its operational arm is called Land Force. It is the largest army in South America and the largest branch of the Armed Forces of Brazil.
Military Police are the uniformed preventive state police of the states and of the Federal District of Brazil. The Military Police units are the main ostensive police force at the state level and are responsible for policing and maintaining the public order. Their formations, rules and uniforms vary depending on the state. Investigative work and forensics are undertaken by the Civil Police of each state.
In Brazil, the Federal Constitution establishes eight law enforcement institutions - seven titulars and one auxiliar. The titular institutions are: the Federal Police, the Federal Highway Police, the Federal Railroad Police, the Federal Penal Police, the State Military Police and Fire Brigade, the State Civil Police and the State Penal Police. Of these, the first four are affiliated to federal authorities and the latter three are subordinated to state governments. These public safety institutions are part of the Executive branch of either federal or state government. Apart from these eight institutions, there are others which affiliate to municipal authorities: the Municipal Guards. According to Minister Alexandre de Moraes of the Supreme Federal Court, "...the Municipal Guards are inserted in public safety as the auxiliary and related body of public security force..." Federal law 13,022 gave them de facto and de jure police attributions.
The Revolution of 1930 was an armed insurrection across Brazil that ended the Old Republic. The revolution replaced incumbent president Washington Luís with defeated presidential candidate and revolutionary leader Getúlio Vargas, concluding the political hegemony of a four-decade-old oligarchy and beginning the Vargas Era.
The Constitutionalist Revolution of 1932 is the name given to the uprising of the population of the Brazilian state of São Paulo against the Brazilian Revolution of 1930 when Getúlio Vargas assumed the nation's presidency; Vargas was supported by the people, the military and the political elites of Minas Gerais, Rio Grande do Sul and Paraíba. The movement grew out of local resentment from the fact that Vargas ruled by decree, unbound by a Constitution, in a provisional government. The 1930 Revolution also affected São Paulo by eroding the autonomy that states enjoyed during the term of the 1891 Constitution and preventing the inauguration of the governor of São Paulo, Júlio Prestes, who had been elected president of Brazil in 1930, while simultaneously overthrowing President Washington Luís, who was governor of São Paulo from 1920 to 1924. These events marked the end of the First Brazilian Republic.
In Brazil, the Civilian Police is the name of the investigative state police forces.

In Brazil, the Military Firefighters Corps are military public security forces, responsible for civil defense, firefighting and search and rescue inside the federative units. Since 1915, it has been a military reserve force and an auxiliary force of the Brazilian Army, also composing the Single System of Public Security. Members of the Military Firefighters Corps, such as the members of the Military Police, are designated as being part of the military of the Federative Units by the Federal Constitution.

The Brazilian cavalry is one of the branches that make up the Brazilian Army. It operates in armored vehicles and, like the infantry, has the role of directly confronting the enemy, but with distinct missions such as reconnaissance and vanguard. It is organized into regiments and squadrons, which are equivalent to the infantry's battalions and companies. Its main types are tank, mechanized, armored and guard. Its troops serve in vehicle crews or as fusiliers on board, who can also fight on foot.
The Public Forces of the states of Brazil were already called "small state armies" in the First Brazilian Republic (1889–1930) due to their martial character. They took part in the various struggles and rebellions of the period alongside, and sometimes against, the Brazilian Army. Their character was hybrid, police and warfare. They emerged in the federalism of the First Republic as shields of state power against central power, represented by the Army, and were dismantled by the federal government in the Vargas Era (1930–1945) onwards, losing their conventional warfare capabilities.
Operation Farroupilha was the temporary transfer of the seat of government of the Brazilian state of Rio Grande do Sul from the Piratini Palace in the capital Porto Alegre to a military brigade barracks in Passo Fundo in the northwest of the state.

The Rio Grande do Sul Revolt of 1925, also called Revolution of 1925, was triggered by opposition civilians, supported by tenentists, aiming to overthrow the state government of the Brazilian state of Rio Grande do Sul and support the Prestes Column. The revolt was planned by exiles, defeated in the previous 1924 revolt, who still recognized the leadership of general Isidoro Dias Lopes. The plan envisaged uprisings in the army and invasions across the border by groups of exiles.
