José Oswald de Andrade Souza (January 11, 1890 October 22, 1954) was a Brazilian poet and polemicist. He was born and spent most of his life in São Paulo. Andrade was one of the founders of Brazilian modernism and a member of the Group of Five, along with Mário de Andrade, Anita Malfatti, Tarsila do Amaral and Menotti del Picchia. He participated in the Week of Modern Art (Semana de Arte Moderna). Andrade is best known for his manifesto of Brazilian nationalism, Manifesto Antropófago (Cannibal Manifesto), published in 1928. Its argument is that Brazil's history of "cannibalizing" other cultures is its greatest strength, while playing on the modernists' primitivist interest in cannibalism as an alleged tribal rite. Cannibalism becomes a way for Brazil to assert itself against European postcolonial cultural domination. The Manifesto's iconic line is "Tupi or not Tupi: that is the question."
