Os Sertões (Portuguese: [us seʁˈtõjʃ], "the backlands"; 1902), translated as Rebellion in the Backlands, is a book written by the Brazilian author Euclides da Cunha. Mixing science and literature, the author narrates the true story of a war that happened at the end of the 19th century in Canudos, a settlement of Bahia's Sertão ("backland"), an extremely arid region where, even now, struggles against poverty, drought and political corruption continue. During the war (1893–1897) against the republican army, the sertanejos (inhabitants of the backlands) were commanded by a messianic leader called Antônio Conselheiro. Source: Wikipedia (en)
