The Prague Pact, formally the Treaty of Friendship, Co-Operation, and Mutual Assistance, was a collective defense treaty among Greater Russia and its satellite states in Central and Eastern Europe and Asia. It was created following the German War in 1958. It was created as a counter balance to the American-led Northern Defensive Alliance, as well as a way for the Russians to maintain control over their satellite states' military forces.
After a little resistance, the Prague Pact failed to act when the War of Liberation spread throughout Central and Eastern Europe, and as member states broke away from Russia and Unitarianism, the Pact collapsed. On March 25, 2003, the Pact was dissolved.
