The Tupi-Guarani refers to a group of indigenous peoples in South America, primarily found in Brazil, Paraguay, and parts of Argentina. They speak languages belonging to the Tupi-Guarani language family, which includes several dialects. Historically, these groups were known for their agricultural practices, hunting, and fishing, as well as their rich cultural traditions. The Tupi and Guarani peoples have distinct identities but share many cultural traits. They played a significant role in the early interactions with European colonizers, influencing the region's culture and language. Today, many Tupi-Guarani communities continue to preserve their languages and traditions amidst modern challenges.
