United Nations formation
The name "United Nations", coined by United States President Franklin D. Roosevelt, was first used in the "Declaration by United Nations" of 1 January 1942, during the Second World War, when representatives of 26 nations pledged their governments to continue fighting together against the Axis Powers. -
Yalta Conference
In early 1945, with World War II in Europe drawing to a close, Franklin Roosevelt (United States), Winston Churchill (Great Britain), and Joseph Stalin (USSR) agreed to meet to discuss war strategy and issues that would affect the postwar world. -
Potsdam Conference
On 16 July 1945, the "Big Three" leaders met at Potsdam, Germany, near Berlin. In this, the last of the World War II heads of state conferences, President Truman, Soviet Premier Stalin and British Prime Ministers Churchill and Atlee discussed post-war arrangements in Europe, frequently without agreement. Future moves in the war against Japan were also covered. The meeting concluded early in the morning of 2 August. -
Truman Doctrine
On Friday, February 21, 1947, the British Embassy informed the U.S. State Department officials that Great Britain could no longer provide financial aid to the governments of Greece and Turkey. -
Marshall Plan
When World War II ended in 1945, Europe lay in ruins: its cities were shattered; its economies were devastated; its people faced famine. In the two years after the war, the Soviet Union’s control of Eastern Europe and the vulnerability of Western European countries to Soviet expansionism heightened the sense of crisis. To meet this emergency, Secretary of State George Marshall proposed in a speech at Harvard University on June 5, 1947, that European nations create a plan for their economic recon -
Berlin Airlift
In early September 1947, the United States had, along with Great Britain, combined their zones into one military province called "Bizonia," hoping to bring security back to the German people. This formal joining helped to provide economic stability to a cash strapped British zone. Soon after, France followed suit and annexed its section to Bizonia. The new Trizone leadership now looked to secure some economic stability in the midst of the German recession. In February 1948, the United States and -
NATO formation
After World War II, the U.S. and the U.S.S.R. occupied much of Europe. Most the the continent's governments had fallen to the Nazis during the war, so the two superpowers were left with the responsibility of setting up new governments. Each promised to allow free elections, but in the end, did not. This left eastern and western Europe divided by style of government (eastern was communist, western was not) and left Germany divided between the two superpowers. -
North Korean Invasion of South Korea
On 25 June 1950, the young Cold War suddenly turned hot, bloody and expensive. Within a few days, North Korea's invasion of South Korea brought about a United Nations' "police action" against the aggressors. That immediately produced heavy military and naval involvement by the United States. While there were no illusions that the task would be easy, nobody expected that this violent conflict would continue for more than three years. Throughout the summer of 1950, the U.S. and the other involved -

Sputnik 1 Launched
History changed on October 4, 1957, when the Soviet Union successfully launched Sputnik I. The world's first artificial satellite was about the size of a beach ball (58 cm.or 22.8 inches in diameter), weighed only 83.6 kg. or 183.9 pounds, and took about 98 minutes to orbit the Earth on its elliptical path. That launch ushered in new political, military, technological, and scientific developments. While the Sputnik launch was a single event, it marked the start of the space age and the U.S.-U.S. -
First Man on the Moon
April 12 was already a huge day in space history twenty years before the launch of the first shuttle mission. On that day in 1961, Russian cosmonaut Yuri Gagarin (left, on the way to the launch pad) became the first human in space, making a 108-minute orbital flight in his Vostok 1 spacecraft. Newspapers like The Huntsville Times (right) trumpeted Gagarin's accomplishment. Mercury astronaut Alan Shepard became the first American in space less than a month later. The first cooperative human spa
