António Raposo Tavares

António Raposo Tavares o Velho (1598–1658) was a Portuguese colonial bandeirante who explored mainland eastern South America and claimed it for Portugal, extending the territory of the colony beyond the limits imposed by the treaty of Tordesillas. He also led the largest expedition ever made in the Americas, covering over 10,000 kilometres around South America, unifying completely the two large South American river basins and the Andes in a single voyage. Raposo Tavares departed from São Paulo towards the rivers of the Río de la Plata Basin and the Andean slopes, and from there to Belém, at the mouth of the Amazon. Raposo Tavares was partly of Jewish origin according to the Jewish historian Anita Novinsky.
