The casa-grande (Portuguese and Spanish: "big house") was the Brazilian equivalent of a Southern plantation in the United States. These casas-grandes were predominantly located in the northeast of Brazil (areas such as present day Bahia and Pernambuco). Additionally, sugar cane was grown in the interior, in the states of São Paulo and Rio de Janeiro.
The casa-grande was made up of three main components: the Big House, the senzala (slave quarters), and the engenho (sugar cane mill). The master of sugar production was called the senhor de engenho ("master of the sugar works"). His word was final, and he had control over the land, the slaves, and the women who made up the plantation community.[1][2]
The larger casas-grandes were self-sustaining, since they were isolated from the more developed coastal regions. Essential structures that were built included the school, the nursery, the infirmary, the family chapel, the master’s harem, the bank, and the cemetery. In the early days it was necessary to maintain an army on the plantation. Those armies were sometimes very large, having up to one hundred Indians/half-breeds.
These plantations constituted a largely self-contained economic, social, political, and cultural system.[3]
