Brazil Military Records

The first regular troop, composed of 600 voluntary soldiers, disembarked for Brazil in 1549 with Governor General Tomé de Souza. In the 17th century there were organized troops (Terço) of white, pretos (Negro/Black), pardos (Mulatto), and Indians, and later there were organized regiments of the militia. After the Dutch war a reserve of soldiers and calvary commanded by the Fazendeiros militaries was organized.

In 1763 the capital was transferred from Bahia to Rio de Janeiro. The Viceroy Guard Calvary Company became the 1st Cavalry Regiment. Other military units were gradually added in Rio de Janeiro and other captaincies. Marine units were formed in the chief ports. After the departure of D. João VI, Prince D. Pedro ordered the organization of the Civil Guard, whose members would serve for three years for the defense of the Court. The National Guard was created by the law of 1831.

To enter into military cadets school in Portugal a person had to submit proof of the nobility of his parents and of all four grandparents. This system existed until 1832. After that date, by decree of D. Pedro, persons of means could also apply for entrance into the military as officers.

Prior to the decree of 1839 the military was not well organized even though a naval academy was created in 1808 and a military academy was established in 1810. Prior to these dates military officers were of the nobility and attended military academies in Portugal. Except for a few Portuguese units in the chief cities of Brazil, most units were militia commanded by Capitan-Mor. Even in the war with Argentina (1825–1828) concerning the territory of Uruguay (Guerra Cisplatina), Brazil had to rely on many mercenaries.

Military records identify individuals who served in the military or who were eligible for service. Most young men were required to serve in or register for military service in Brazil. Evidence that an ancestor actually served may be found in family records, biographies, censuses, probate records, civil registrations, and church records.

Military records are potentially of great genealogical value. Military records begin about 1750 and give information about an ancestor’s military career, such as promotions, places served, pensions, and conduct. In addition, these records usually include information about:

To use Brazilian military records you will have to determine the specific unit your ancestor served in. If your family records do not provide this information it may be possible to learn which units were created in the area where he lived. To do this you must know at least the town where the individual was living when he was of age to serve in the military. For military history, consult:
