Today, Tanzania is one of Africa's most progressive, peaceful and democratic nations. A real testament to the Tanzanian people who have built it that way.
Like many African nations, Tanzania has had it's share of foreign intervention, domination and exploitation. In 1840, Arab slave traders occupied most of the coast and turned Zanzibar into the center of the Arab slave trade, eventually enslaving up to 90% of the population.
In the late 19th century, Imperial Germany conquered the regions that are now Tanzania (minus Zanzibar), Rwanda and Burundi. The consolidated region became German East Africa. After World War I, the region became a British Mandate with the exception of the area that is presently Rwanda and Burundi.
British rule ended in 1961 after a relatively peaceful transition to independence. Julius Nyerere became Minister of British-administered Tanganyika in 1960 and continued as Prime Minister when Tanganyika became independent in 1961.
After the Zanzibar Revolution overthrew the Arab dynasty in neighboring island of Zanzibar, which had become independent in 1963, the island merged with mainland Tanganyika to form the nation of Tanzania in 1964. One-party rule came to an end in 1995 with the first democratic elections held in the country since the 1970s.
