Mbai-yurú

Mbai-yurú, the Tupi-derived name later rendered as Bauru, belonged to the interior plateau where the Tietê, Paranapanema and Paraná basins approach one another. Forests and streams crossed rolling land, and the Batalha and Bauru rivers provided water and routes. Seasonal rain fed springs and small wetlands across the plateau. Kaingang and Guarani communities used and contested this broad country before outsiders established farms.

The area formed a crossing point for expeditions moving from São Paulo toward Mato Grosso and Goiás. During the eighteenth century, bandeirante attempts to settle were resisted by Indigenous groups. Families relied on hunting, fishing, forest gathering and small cultivation, with trails connecting river valleys and high ground. The Batalha corridor provided an inland passage between the Paraná basin and the plateau.

The name Bauru had several possible origins: a steep river or waterfall, a basket of fruits, or the people living along the Batalha. Permanent non-Indigenous settlement belonged to a later phase, when newcomers arrived from coastal São Paulo, Minas Gerais and Rio de Janeiro. Before those farms and the town that followed, Bauru’s identity remained tied to the Indigenous country between the great river systems.
