Tanzania
The flag of Tanzania was adopted on 30 June 1964. It was a merger of the flags of Tanganyika and Zanzibar. The flag is divided diagonally by a yellow-edged black band from the lower hoist-side corner. The upper triangle (hoist side) is green and the lower triangle is blue. The meaning of the colours is as follows: green represents the natural vegetation present in the country, gold represents the rich mineral deposits of the country, black represents the skin colour of Tanzanians, and blue represents the numerous lakes and rivers and the Indian Ocean.
