You proabably mean Tanganyika, the former name of a country in Africa.
Yes, the name was changed in 1964.

He made "Hatari" in Tanganyika in 1962.
Tanganyika formed part of the country that is now called Tanzania. The capital of Tanganyika was Dar es Salaam. There is also a lake called Lake Tanganyika.
Tanzania actually used to be two different countries. It was formed from a colony named Tanganyika and an island named Zanzibar. They made the name like this: Tan [ganyika] + Zan [zibar] + ia [ suffix for country ]. I hope that's good enough.
Lake Tanganyika is on the continent of Africa.
The Tanganyika Rifles ended in 1964.
