"Casa-Grande e Senzala" is a seminal work by Brazilian sociologist Gilberto Freyre, published in 1933. The book explores the social and cultural dynamics of colonial Brazil, focusing on the relationships between the Portuguese colonizers, African slaves, and indigenous peoples. Freyre examines how these interactions shaped Brazilian society, particularly in terms of race, class, and family structures. Freyre's analysis emphasizes the importance of the casa-grande (the master's house) and the senzala (the slave quarters) as symbols of the plantation system. He argues that the blending of cultures led to a unique Brazilian identity, characterized by a mix of traditions, customs, and social practices.
