Bandeirantes

Bandeirantes (Portuguese: [bɐ̃dejˈɾɐ̃tʃis]; lit. 'flag-carriers'; singular: bandeirante) were frontiersmen and explorers in colonial Brazil who, from the early 16th century, participated in inland expeditions to find precious metals and enslave indigenous peoples. They played a major role in expanding Brazil's borders to its approximate modern-day limits, beyond the boundaries demarcated by the 1494 Treaty of Tordesillas.

Most bandeirantes hailed from São Paulo, then a small village in the Captaincy of São Vicente from 1534 to 1709 and later the Captaincy of São Paulo from 1720 to 1821. Some bandeirantes were descended from Portuguese colonists who settled in São Paulo, but most were of mameluco descent with both Portuguese and indigenous ancestry. This was due to miscegenation being the norm in colonial Brazilian society, as well as polygamy.

Initially, the bandeirantes aimed to explore and expand the Portuguese colonial territory beyond the boundaries established by the Treaty of Tordesillas. They ventured into unmapped regions in search of economic opportunities, particularly the discovery of gold, silver, and diamonds. Over time, as their expeditions progressed, the bandeirantes also began to capture and enslave indigenous peoples, which became a significant part of their activities. Their primary goal remained the expansion of territory and the search for resources, which played a major role in shaping the modern borders of Brazil. The bandeirantes spoke a mixture of Portuguese and the Paulista General Language, which influenced the toponyms and place names in the interior of the colony to this day.
