The history of Sete Lagoas began at the dawn of the 18th century, during the Brazilian gold rush. The area received its name, which translates to "Seven Lakes," due to a picturesque chain of seven lagoons that became its primary geographical feature. The founder of the settlement is considered to be the bandeirante explorer from São Paulo, João Leite da Silva Ortiz, who arrived in the region around 1700. In 1711, he received an official land grant, marking the beginning of the future city.
Several key factors determined the development of Sete Lagoas. Its location in the resource-rich state of Minas Gerais and the presence of the lake system facilitated early agricultural development. The region was originally part of the gold seekers' routes, but like many settlements in the state, it later focused on the agrarian sector and livestock. A new push for city growth in the 19th and 20th centuries came with the construction of railways and industrial plants.
In its early stages, Sete Lagoas was a large estate oriented toward self-sufficiency and supporting expeditions. The first settlers were adventurers and migrants from São Paulo who were exploring the country's interior. The culture was shaped by the traditions of these enterprising and independent people. Gradually, with population growth and the development of transport links, the settlement transformed into an important regional hub.
