Having taken control of the island, John Okello invited Abeid Karume back to the island to assume the title of President of the
People's Republic of Zanzibar. Other Zanzibaris in foreign territory were also invited back, most notably the Marxist politician
Abdulrahman Mohammad Babu, who was appointed to the Revolutionary Council. John Okello reserved for himself the title of "Field Marshal", a position with undefined power. What followed was a three-month-long internal struggle for power. Karume used his political skills to align the leaders of neighboring African countries against Okello and invited Tanganyikan police officers into Zanzibar to maintain order. As soon as Okello took a trip out of the country, Karume declared him an "enemy of the state" and did not allow him to return. Given the presence of Tanganyikan police and the absence of their leader, Okello's gangs of followers did not offer any resistance. Karume's second important political move came when he agreed with the Tanganyikan president
Julius Nyerere in that Zanzibar would form a union with Tanganyika. As a result, Karume was rewarded with the post of
First Vice-President. The union ensured that the new country, to be called
Tanzania, would not align itself with the
Soviet Union and communist bloc, as A.M. Babu had advocated. Given the new legitimacy of Karume's government (now solidly backed up by mainland Tanganyika), Karume marginalized Babu to the point of irrelevance. The Marxist leader was eventually forced to flee Tanzania after being charged with masterminding the assassination of Karume in 1972. == Personal life ==
