The Yalta Conference in 1945,where the leaders of the Allied Powers sought not only to conclude the Second World War but also to determine the nature of the post-war world.
The Cold War is the long period of time after the Second World War where political and military tensions existed between the Eastern bloc of nations (the Soviet Union and her satellite states) and the Western bloc (the United States and her allies).
At its worst, the Cold War tensions escalated to terrifying heights which would threaten to spiral out of control, plunging the world into nuclear war. An example of this was the Cuban Missile Crisis of 1962.
The nearly-two weeks which marked the Cuban Missile Crisis was made into an excellent movie titled Thirteen Days. It recreates the tension and strain of those dramatic days very vividly.
Although an all-out cataclysmic nuclear war was successfully averted, many "small" wars and military conflicts did occur, such as the Korean War, the Malayan Emergency and the Vietnam War.
Some very helpful websites on the Cold War include:

The Cold War video channel. Many different and little known features of the Cold War era brought to life here.
The Cold War era was also known for its espionage. Many countries engaged spies to infiltrate enemy nations, operate undercover and obtain highly sensitive intelligence. Many Hollywood movies have been produced with such scenarios providing the backdrop.
This dramatic four or five decades between the late 1940s and the early 1990s was also marked by strident and vocal social movements, many of which were anti-establishment in nature. Anti-war protests were common in the USA, and the constant threat of war turned many young people against their governments as well as against many commonly-accepted social norms.
Here is a quick summary of the Cold War.
