Tanzania was formed in 1964 by the union of Tanganyika and Zanzibar, two recently British-independent countries. Not only the name (Tan + Zan = Tanzania), but also the flag of the recently established Tanzania is a mix of the two former countries.
|Republic of Tanganyika (1961-1964)||People's Republic of Zanzibar and Pemba (1961)|
And now note how all the elements of these flags are visible in the United Republic of Tanzania:
You can see Tanganyika flag here, but you can also see the Zanzibar flag (a little upside-down, but you do). Pretty ingenious, isn't it? The design is so subtle that it looks like a totally original flag.
What do you think about the post? Did you know the curious origin of Tanzanian flag? Comment, please.
