Military Police of Minas Gerais State

The PMMG's primary mission is to deter and control crime throughout the state, often by patrolling streets or public facilities in cities, such as schools. However, it is also responsible for monitoring the open lands, forests, rivers, and highways of Minas Gerais, and will even carry out reconnaissance missions, referred to as P2.

The force is divided evenly between Belo Horizonte, the capital of Minas Gerais, and the remaining cities and districts. The PMMG's administrative structure consists of 15 regions, subdivided into large battalions down to individual detachments, which always consist of a minimum of 4 officers to a county.

Towards the end of the seventeenth century, gold was discovered in Minas Gerais, and as miners began finding other ores and gems, waves of migrants from all over Brazil began a gold rush to the state. Within the chaotic mass of newcomers, violence and disorder became prevalent enough to worry colonial Portuguese authorities. At least as concerned about collecting taxes on the newfound mineral wealth as stopping the lawlessness, Governor Pedro Miguel de Almeida requested two companies of Portuguese dragoons from the King of Portugal.

However, discipline rapidly broke down among the Portuguese soldiers, and many deserted to become prospectors themselves. The people of Minas Gerais wanted a capable and loyal force to maintain order and punish wrongdoers, but not a heavy-handed unit focused on imposing Portuguese regulations. As a result, on June 9, 1775 the governor, Don Antonio de Noronha, would officially disband the Portuguese dragoons and replace them with the Regular Cavalry Regiment of Mines.

This new police force consisted entirely of Minas Gerais locals, or mineiros, who would be more passionate about protecting their own neighbors and lands. These new officers would also receive regular salaries from the treasury, in order to discourage taking bribes or deserting to pan and mine for gold. From the beginning of its existence, the regiment would engage in both normal police actions, like catching criminals, and military actions like putting down insurrections. Despite this, the regiment would not develop more military characteristics until after Brazilian Independence and the establishment of the Republic. With the help of Robert Drexler, a military advisor and colonel in the Swiss Army, the force would begin receiving full military training.

In the years since, legal and political changes have adjusted the powers and resources of the PMMG. Decree-Law 667 and its later amendments would give the PMMG the constitutional obligation to maintain the public peace, along with the power to independently plan and carry out civilian policing. The concept of "police authority" was also interpreted as substantially different from previous practice. In 1988, the Constituents of the Republic established a Public Safety System consisting of law enforcement agencies. By Article 144 of the Constitution, each agency retained its independence and structure, but with both more cooperation and checks on power. This reform was intended to help all agencies better fight crime while protecting citizens from abuses and rights violations.

Brazilian former president Juscelino Kubitschek (1902–1976) was a medical doctor and commissioned as a captain in the PMMG.

The famed writer Guimarães Rosa (1908–1967) also served as a volunteer medical doctor in the PMMG, but he never held military rank.

The hero of the troop, Fulgêncio de Sousa Santos (1896–1932), also served in the PMMG, reaching the rank of colonel.
