The Atlantic Charter was an agreement signed between the United States and Great Britain on August 14, 1941. It was a joint declaration of principles that set out the goals of the Allied powers in World War II and became a cornerstone of the post-war international system.

The agreement was signed by US President Franklin D. Roosevelt and British Prime Minister Winston Churchill aboard the HMS Prince of Wales, anchored off the coast of Newfoundland. The two leaders had met to discuss the war effort and to establish a common vision for the post-war world.

The Atlantic Charter laid out eight key principles, including the renunciation of territorial aggrandizement, the promotion of economic cooperation, and the right of all peoples to choose their own form of government. The charter also called for the establishment of a system of international security that would ensure the peaceful resolution of conflicts.

Though the charter was not legally binding, it served as a statement of Allied goals and principles and helped to solidify the relationship between the US and Great Britain. It was also seen as a symbol of the commitment of the Allied powers to defeat Nazi Germany and secure a peaceful, prosperous post-war world.

The principles laid out in the Atlantic Charter continue to resonate today, particularly in the areas of human rights, economic cooperation, and international diplomacy. The charter is widely regarded as a precursor to the creation of the United Nations and the post-war international order that emerged from the devastation of World War II.

In conclusion, the Atlantic Charter was an important agreement signed between the United States and Great Britain during World War II. It laid out key principles and goals for the Allied powers and helped to establish a foundation for the post-war international system. Its legacy continues to be felt today in areas such as human rights, economic cooperation, and international diplomacy.
