"Raízes do Brasil" is a seminal book written by Brazilian sociologist Sérgio Buarque de Holanda in 1936. It explores the formation of Brazilian identity and culture, emphasizing the influence of Portuguese colonization and the unique social dynamics that emerged in Brazil. The work examines how these historical factors shaped the country's political and social structures. The book is notable for its analysis of the patrimonialism in Brazil, where personal relationships often overshadow formal institutions. Buarque de Holanda argues that this characteristic has deep roots in Brazilian society, affecting governance and social interactions throughout the nation's history.
