apr 4, 1949 - North Atlantic Treaty

Description:

North Atlantic Treaty - Establishment of NATO
The North Atlantic Treaty, signed on April 4, 1949, became the largest modern peacetime alliance. Due to tensions between the Western World and the Soviet Union, many European states became increasingly involved in constructing an intercontinental union. After the Korean War, which many believed to be influenced by the communist uprise in the Soviet Union, and the rise of communists in Italy and Germany, many nations realized that the safest way to approach the upcoming Cold War was through mutually beneficial alliances. The treaty signifies the connection between the United States, Canada, and many European nations; it birthed the North Atlantic Treaty Organization, which is known by its acronym NATO, and marks the beginning of the longest peacetime military alliance since the Industrial Revolution.
Initially, NATO consisted of 12 Nations: Belgium, Canada, Denmark, France, Iceland, Italy, Luxembourg, the Netherlands, Norway, Portugal, the United Kingdom, and the United States. Since then, NATO has added a multitude of countries to its protection. In 1952, Greece and Turkey joined; in 1955, the Federal Republic of Germany was added; in 1982, Spain joined; post-Cold War, in 1999, Poland, Czechia, and Hungary were admitted; in 2004, Bulgaria, Estonia, Latvia, Lithuania, Romania, Slovakia and Slovenia joined. Since then, six other countries have joined, totaling 32 nations. NATO has only needed to enact Article 5 once, which states that if any member is attacked, all members must come to their assistance. It was invoked after the 9/11 attacks, organized by Osama bin Laden, to ensure the safety of American Citizens and pursue justice for the terrorist attacks.
