brazil's largest african and mixed populations are in
Demographics of Brazil In the Northeast, which received large masses of African slaves to work in sugarcane, tobacco and cotton plantations, people of African and mixed-race descent predominate, mostly on the coast, whereas in the semi-arid country land (usually called sertão) there is a predominance of white and Amerindian-European mixed people. Most of the black or mulatto people in the sertão are descended from freed African slaves or mulattos who fled inland from the coast and worked as cowboys for semi-feudal lords. The city of Salvador da Bahia is considered one of the largest black cities of the world. In the Northwest (covering largely the Brazilian Amazon), a great part of the population has distinguishable ethnic characteristics that emphasize their Amerindian roots. Other ethnic groups have merged with the Indigenous tribes there. This region is not densely populated, and "caboclos", people of mixed native and European descent, are a small part of the entire Brazilian population.
Colonial Brazil Colonial Brazil (Portuguese: Brasil Colonial) comprises the period from 1500, with the arrival of the Portuguese, until 1815, when Brazil was elevated to a kingdom in union with Portugal as the United Kingdom of Portugal, Brazil and the Algarves. During the early 300 years of Brazilian colonial history, the economic exploitation of the territory was based first on brazilwood (pau brazil) extraction (16th century), which gave the territory its name;[1] sugar production (16thâ€“18th centuries); and finally on gold and diamond mining (18th century). Slaves, especially those brought from Africa, provided most of the work force of the Brazilian export economy after a brief period of Indian slavery to cut brazilwood.
