|In 1964, showing its commitment to the ideal of African unity, Tanganyika merged with the island state of Zanzibar to form the new country of Tanzania. This merger is the only successful attempt to merge two former African colonies.While vibrant for more than a decade, the East Community dissolved in the mid-1970s as a result of strong disagreements between Uganda and the rest of the community over the policies of the then Ugandan dictator Idi Amin.In spite of the failure of the East African community, Tanzania pursued its commitment to African unity and African liberation through its active support of national liberation movements throughout southern Africa. Beginning in the mid-1960s, Tanzania invited liberation movements from neighboring Mozambique, Namibia, Angola, and South Africa to set up military bases and training centers in Tanzania. The current leaders of these countries are grateful for the support that Tanzania offered during their struggles for freedom. There is agreement within southern Africa that no other country in Africa offered as much support for their liberation as did Tanzania.
It was through this active engagement with the liberation struggles in southern Africa that Tanzania became actively involved in the regional organizations such as SADCC and SADC that promote economic and political cooperation and integration.
