In 1964 there were two States in East Africa that merged to form a union. The names of these states were Tanganyika and Zanzibar. Tanganyika was declared independence from the British on 9th December 1961 and Zanzibar on 10th December 1963. However, on January 12, 1964, the government that was entrusted independence in Zanzibar was overthrown in a bloody coup and just within three months later, the Tanganyika and Zanzibar Presidents signed an agreement to unite their states into a single sovereign state. Through this agreement, a new sovereign state and a new government was established under the name of the United Republic of Tanganyika and Zanzibar. According to the current structure of the United Republic, the powers of the Tanganyika government has been transferred to the Union government while Zanzibar has since then remained as an autonomous government. Therefore, while Tanganyika is no longer in an actual existence, Tanzania as a unitary sovereign state constitutes two governments; the union, and the Zanzibar government. The aim of this study is to examine the legality of the union between the Republic of Tanganyika and the People's Republic of Zanzibar in terms of both constitutional law and international law. In this context, the research starts by examining the historical background of these two countries. The research also examines important areas of international and national law that were not fully determined during the implementation of the union treaty between the Republic of Tanganyika and the People's Republic of Zanzibar. Finally, the research puts forward recommendations that can be used to solve the unconstitutionality of the union for the bright future of the people of Tanzania.
