What was the name of the communist collective security alliance with ties to Poland?

The Warsaw Pact was a collective security alliance formed in 1955 among the Soviet Union and several Eastern Bloc socialist republics, including Poland. It was established as a response to NATO, which included Western democratic nations. The primary aim of the Warsaw Pact was to solidify military cooperation among its member states and to counter the influence of Western powers during the Cold War. The alliance allowed the Soviet Union to maintain a significant level of control over the military and political activities within Eastern Europe, showcasing the division between the communist bloc and the capitalist Western nations. This context is essential for understanding how the Warsaw Pact functioned in relation to Poland and the broader geopolitical landscape of the time.
