Introduction ✍🏾

The Tanzania Intelligence and Security Service (TISS) played a pivotal role in African geopolitics during the Cold War, balancing between Western and Eastern blocs while combating apartheid South Africa’s espionage machine. Under the visionary leadership of Julius Nyerere, TISS not only shielded Tanzania from foreign subversion but also became a central pillar in supporting liberation movements across Southern Africa. Its intelligence networks, coordination with socialist allies, and dedication to African liberation made it one of the most active and politically influential security services on the continent.
