Tanzania Intelligence and Security Service (TISS) traces its originstom the British Colonial Period, where Special Branch (SB) was created as a department of the Tanganyika Police Force. The department worked operated independently from the then Criminal Investigation Department (CID).
The idea of its formation took root in the year 1947 as advised by the British Intelligence MI6 which was responsible for espionage activities in the UK and its colonies. MI6 wanted its establishment of the department in Tanganyika just like BritainâÂÂs other colonies like Kenya, Uganda, Rhodesia etc, and while as freedom movement In Tanganyika intensified under Tanganyika African National Union (TANU) now Chama Cha Mapinduzi (CCM) led to a fast development of Special Branch that by the year 1958 it had 4 Zonal Offices in 4 Provinces out of the total 8 Provinces.
It is from the year 1958 even more Police Officers were enrolled in the department and received special training to sharpen their skills related to espionage. The first security guard of the Late President Julius Kambarage Nyerere, , served in as a Special Branch Officer in the Lake Victoria Zone from 1953 to 1958. At the time, the main role of Special Branch was to spy on the activities of Tanganyika African National Union (TANU) leaders including Mwl. Julius Kambarage Nyerere, Oscar Kambona, Rashid Kawawa, Asanterabi Zephaniah Nsilo Swai and many more to Freedom Movement leaders to determine their political direction.
In August 1961 was created a special force for the protection of leaders including the then Prime Ministers Julius Kambarage Nyerere. After Tanganyika Independence on December the same year, just like other sensitive departments, Special Branch (SB) was still under the British Colonial Control and most of its leaders we still British. The only Tanganyikan with a relatively high position was Emilio Charles Mzena who by then was the Assistant Superintendent of Police (ASP). The then Africanization Movement that was led by TANU that wanted Africana to be given Power in leadership led to Emilio Charles Mzena being appointed as the first Director General of Special Branch (SB) on June 1962. Emilio Charles Mzena, and Lawrence Gama were among African-origin Special Branch Members that got their training in Several British institutions in the 1950s.
