The Allies of World War II, called the "United Nations" from the 1 January 1942 declaration, were the countries that together opposed the Axis powers during the Second World War (1939–1945). The Allies promoted the alliance as a means to control German, Japanese and Italian aggression.

United States Federal republic in North America

The United States of America (USA), commonly known as the United States or America, is a country comprising 50 states, a federal district, five major self-governing territories, and various possessions. At 3.8 million square miles, the United States is the world's third or fourth largest country by total area and is slightly smaller than the entire continent of Europe's 3.9 million square miles. With a population of over 327 million people, the U.S. is the third most populous country. The capital is Washington, D.C., and the largest city by population is New York City. Forty-eight states and the capital's federal district are contiguous in North America between Canada and Mexico. The State of Alaska is in the northwest corner of North America, bordered by Canada to the east and across the Bering Strait from Russia to the west. The State of Hawaii is an archipelago in the mid-Pacific Ocean. The U.S. territories are scattered about the Pacific Ocean and the Caribbean Sea, stretching across nine official time zones. The extremely diverse geography, climate, and wildlife of the United States make it one of the world's 17 megadiverse countries.

United Kingdom Country in Europe

The United Kingdom (UK), officially the United Kingdom of Great Britain and Northern Ireland, and sometimes referred to as Britain, is a sovereign country located off the north-western coast of the European mainland. The United Kingdom includes the island of Great Britain, the north-eastern part of the island of Ireland, and many smaller islands. Northern Ireland is the only part of the United Kingdom that shares a land border with another sovereign state, the Republic of Ireland. Apart from this land border, the United Kingdom is surrounded by the Atlantic Ocean, with the North Sea to the east, the English Channel to the south and the Celtic Sea to the south-west, giving it the 12th-longest coastline in the world. The Irish Sea lies between Great Britain and Ireland. With an area of 242,500 square kilometres (93,600 sq mi), the United Kingdom is the 78th-largest sovereign state in the world. It is also the 22nd-most populous country, with an estimated 66.0 million inhabitants in 2017.

In total Churchill attended 16 meetings, Roosevelt 12, Stalin 7.

For some of the major wartime conference meetings involving Roosevelt and later Truman, the code names were words which included a numeric prefix corresponding to the ordinal number of the conference in the series of such conferences. The third conference was TRIDENT, the fourth conference was QUADRANT, the sixth conference was SEXTANT, and the eighth conference was OCTAGON. The last wartime conference was code-named TERMINAL.

A code name or cryptonym is a word or name used, sometimes clandestinely, to refer to another name, word, project or person. Names are often used for military purposes, or in espionage. They may also be used in industrial counter-industrial espionage to protect secret projects and the like from business rivals, or to give names to projects whose marketing name has not yet been determined. Another reason for the use of names and phrases in the military is that they transmit with a lower level of cumulative errors over a walkie-talkie or radio link than actual names.

Tehran Conference convention

The Tehran Conference was a strategy meeting of Joseph Stalin, Franklin D. Roosevelt, and Winston Churchill from 28 November to 1 December 1943, after the Anglo-Soviet Invasion of Iran. It was held in the Soviet Union's embassy in Tehran, Iran. It was the first of the World War II conferences of the "Big Three" Allied leaders. It closely followed the Cairo Conference which had taken place on 22–26 November 1943, and preceded the 1945 Yalta and Potsdam conferences. Although the three leaders arrived with differing objectives, the main outcome of the Tehran Conference was the Western Allies' commitment to open a second front against Nazi Germany. The conference also addressed the 'Big Three' Allies' relations with Turkey and Iran, operations in Yugoslavia and against Japan, and the envisaged post-war settlement. A separate protocol signed at the conference pledged the Big Three to recognize Iran's independence.

Yalta Conference

1943 Cairo Declaration outcome of the 1943 Cairo Conference

The Cairo Declaration was the outcome of the Cairo Conference in Cairo, Egypt, on November 27, 1943. President Franklin Roosevelt of the United States, Prime Minister Winston Churchill of the United Kingdom, and Generalissimo Chiang Kai-shek of the Republic of China were present. The declaration developed ideas from the 1941 Atlantic Charter, which was issued by the Allies of World War II to set goals for the post-war order. The Cairo Communiqué was broadcast through radio on December 1, 1943.

Europe first, also known as Germany first, was the key element of the grand strategy agreed upon by the United States and the United Kingdom during World War II. According to this policy, the United States and the United Kingdom would use the preponderance of their resources to subdue Nazi Germany in Europe first. Simultaneously, they would fight a holding action against Japan in the Pacific, using fewer resources. After the defeat of Germany—considered the greatest threat to the UK—all Allied forces could be concentrated against Japan.

Office of Censorship

The Office of Censorship was an emergency wartime agency set up by the United States federal government on December 19, 1941 to aid in the censorship of all communications coming into and going out of the United States, including its territories and the Philippines. The efforts of the Office of Censorship to balance the protection of sensitive war related information with the constitutional freedoms of the press is considered largely successful. The agency's implementation of censorship was done primarily through a voluntary regulatory code that was willingly adopted by the press. The phrase, "loose lips sink ships" was popularized during World War II, which is a testament to the urgency Americans felt to protect information relating to the war effort. Radio broadcasts, newspapers, and newsreels were the primary ways Americans received their information about World War II and therefore were the medium most affected by the Office of Censorship code. The closure of the Office of Censorship in November 1945 corresponded with the ending of World War II.

Frederick James Leathers, 1st Viscount Leathers, was a British industrialist and public servant.

A summit meeting is an international meeting of heads of state or government, usually with considerable media exposure, tight security, and a prearranged agenda. Notable summit meetings include those of Franklin D. Roosevelt, Winston Churchill, and Joseph Stalin during World War II. However, the term summit was not commonly used for such meetings until the Geneva Summit (1955). During the Cold War, when American presidents joined with Soviet or Chinese counterparts for one-on-one meetings, the media labelled the event as a "summit". The post–Cold War era has produced an increase in the number of "summit" events. Nowadays, international summits are the most common expression for global governance.

Second Cairo Conference

Roosevelt of the United States, Prime Minister Winston Churchill of the United Kingdom, and President İsmet İnönü of the Republic of Turkey.

Washington Conference (1943)

The Third Washington Conference was held in Washington, D.C from May 12 to May 25, 1943.

It was the third conference of the 20th century, but the second conference that took place during the US involvement in the Second World War. The delegations were headed by Winston Churchill and Franklin D. Roosevelt, respectively.

The Second Washington Conference, did not have a code name because it was hastily called and was regarded at the time as a set of military staff conversations rather than a formal conference. The two delegations were led by the British Prime Minister Winston Churchill and the American President Franklin D. Roosevelt.

The following is a timeline of the first premiership of Winston Churchill, who was the Prime Minister of the United Kingdom from 1940 to 1945 and again from 1951 to 1955. Churchill served as the Prime Minister of the United Kingdom during the bulk of World War II. His speeches and radio broadcasts helped inspire British resistance, especially during the difficult days of 1940–41 when the British Commonwealth and Empire stood almost alone in its active opposition to Nazi Germany. He led Britain as Prime Minister until victory over Nazi Germany had been secured. for the general history see Timeline of the United Kingdom home front during World War II.
