Foundation and First Mentions
The history of Três Lagoas begins long before its official recognition. The first settlers, known as "sertanejos" (backcountry pioneers), began developing these lands in the late 19th century. Among the pioneers, Protázio Garcia Leal and Antônio Trajano dos Santos stand out, having established the first livestock farms here around the 1880s.
A decisive moment was the arrival of engineers in 1909 for the construction of the railway, who set up camp near the banks of Lagoa Maior. The official founding date is considered **June 15, 1915**, when the settlement received municipality status. The city received its name ("Three Lakes") thanks to three large water bodies located within the city limits.
Key Factors of Development
The transformation of a small settlement into an important regional centre was driven by several strategic factors:
- Noroeste Railway (Noroeste do Brasil): The construction of the railway line connecting the state of São Paulo with the west of the country became the main catalyst for growth. The opening of the station in 1912 and the completion of the bridge over the Paraná River turned the city into a key transport hub.
- Geographical Location: Its location on the border with the state of São Paulo, by the Paraná River, made the city a natural "gateway" to the state of Mato Grosso do Sul.
- Water Resources: The presence of major rivers (Paraná, Sucuriú) and lakes provided not only water but also transport routes, and later — energy potential.
Early Cultural and Economic Features
In the early decades, the economy of Três Lagoas was based on extensive cattle ranching. Cattle were the foundation of the local landowners' wealth, and the railway allowed for the efficient transport of produce to the markets of São Paulo.
The cultural character of the city was formed at the intersection of the traditions of cattle herders (who came mainly from the state of Minas Gerais) and the lifestyle of railway workers. This created a unique atmosphere where traditional rural customs coexisted with the technical progress of the early 20th century.
