Tanzania is the largest country in East Africa. Modern Tanzania combines two areas that at other times have been governed separately: Tanganyika on the coast of the African mainland and the island of Zanzibar nearby.
Tanzania is probably one of the oldest known continuously inhabited areas on Earth; fossil remains of humans and pre-human hominids have been found dating back over two million years. More recently, Tanzania is believed to have been populated by hunter-gatherer communities, probably Cushitic and Khoisan speaking people. About 2000 years ago, Bantu-speaking people began to arrive from western Africa in a series of migrations. Later, Nilotic pastoralists arrived, and continued to immigrate into the area through to the 18th century.
