TheSultanate of Zanzibar – which was a Britishprotectorate until 1963[2] – used a red flag during its reign over the island. The last sultan was overthrown in theZanzibar Revolution on 12 January 1964, and theAfro-Shirazi Party – the ruling political party of the newly formedPeople's Republic of Zanzibar – adopted a national flag the next month that was inspired by its own party flag.[3][4] This consisted of a tricolour with three horizontal blue, black and green bands.[3]
In April 1964, both Tanganyika and Zanzibar united in order to form a single country – the United Republic ofTanzania.[2] Consequently, the flag designs of the two states were amalgamated to establish a new national flag.[3][5] The green and black colours from the flag of Tanganyika were retained along with the blue from Zanzibar's flag,[4] with a diagonal design used "for distinctiveness".[3] This combined design was adopted on 30 June 1964.[4] It was featured on the first set of stamps issued by the newly unified country.[6] Since 2005, Zanzibar has also used its own regional flag: a horizontal arrangement of blue, black, and green with the national flag of Tanzania in the canton. The design reflects Zanzibar’s identity within the union while maintaining visual ties to Tanzania’s national colours.[7]
The colors and symbols of the flag carry cultural, political, and regional meanings. The green alludes to the natural vegetation and "rich agricultural resources" of the country,[3][5] while black represents theSwahili people who are native to Tanzania.[5] The blue epitomizes theIndian Ocean,[3] as well as the nation's numerous lakes and rivers.[5] The thin stripes stand for Tanzania's mineral wealth,[3][4][8] derived from the "rich deposits" in the land.[5] WhileWhitney Smith in theEncyclopædia Britannica andDorling Kindersley'sComplete Flags of the World describe thefimbriations as yellow,[3][4] other sources – such asThe World Factbook and Simon Clarke in the journalAzania: Archaeological Research in Africa – contend that it is actually gold.[5][8]
13 horizontal stripes. 4 red, 4 green, 2 white and 3 yellow with 8 green crescent moons. 3 in the superior and inferior yellow stripes and 2 in the central yellow stripe.
