Allies of World War IIThe Allies, formally referred to as the United Nations from 1942, were an international military coalition formed during the Second World War (1939–1945) to oppose the Axis powers, led by Nazi Germany, the Empire of Japan, and the Kingdom of Italy. Its principal members by the end of 1941 were the United Kingdom, United States, Soviet Union, and China. Membership in the Allies varied during the course of the war. When the conflict broke out on 1 September 1939, the Allied coalition consisted of the United Kingdom, France, and Poland, as well as their respective dependencies, such as British India.
Katyn massacreThe Katyn massacre was a series of mass executions of nearly 22,000 Polish military officers and intelligentsia prisoners of war carried out by the Soviet Union, specifically the NKVD ("People's Commissariat for Internal Affairs", the Soviet secret police) in April and May 1940. Though the killings also occurred in the Kalinin and Kharkiv prisons and elsewhere, the massacre is named after the Katyn forest, where some of the mass graves were first discovered by German Nazi forces.
United StatesThe United States of America (U.S.A. or USA), commonly known as the United States (U.S. or US) or America, is a country primarily located in North America and consisting of 50 states, a federal district, five major unincorporated territories, nine Minor Outlying Islands, and 326 Indian reservations. It is the world's third-largest country by both land and total area. It shares land borders with Canada to its north and with Mexico to its south and has maritime borders with the Bahamas, Cuba, Russia, and other nations.
Polish Underground StateThe Polish Underground State (Polskie Państwo Podziemne, also known as the Polish Secret State) was a single political and military entity formed by the union of resistance organizations in occupied Poland that were loyal to the Government of the Republic of Poland in exile in London. The first elements of the Underground State were established in the final days of the German and Soviet invasion of Poland, in late September 1939.
Polish government-in-exileThe Polish government-in-exile, officially known as the Government of the Republic of Poland in exile (Rząd Rzeczypospolitej Polskiej na uchodźstwie), was the government in exile of Poland formed in the aftermath of the Invasion of Poland of September 1939, and the subsequent occupation of Poland by Germany, the Soviet Union, and the Slovak Republic, which brought to an end the Second Polish Republic.
Polish population transfers (1944–1946)The Polish population transfers in 1944–1946 from the eastern half of prewar Poland (also known as the expulsions of Poles from the Kresy macroregion), were the forced migrations of Poles toward the end and in the aftermath of World War II. These were the result of a Soviet Union policy that had been ratified by the main Allies of World War II. Similarly, the Soviet Union had enforced policies between 1939 and 1941 which targeted and expelled ethnic Poles residing in the Soviet zone of occupation following the Nazi-Soviet invasion of Poland.
KresyEastern Borderlands (Kresy Wschodnie) or simply Borderlands (Kresy, ˈkrɛsɨ) was a term coined for the eastern part of the Second Polish Republic during the interwar period (1918–1939). Largely agricultural and extensively multi-ethnic, it amounted to nearly half of the territory of pre-war Poland. Historically situated in the eastern Polish–Lithuanian Commonwealth, following the 18th-century foreign partitions it was divided between the Russian Empire and the Austro-Hungarian Empire, and ceded to Poland in 1921 after the Peace of Riga.
CommunismCommunism (from Latin communis) is a left-wing to far-left sociopolitical, philosophical, and economic ideology within the socialist movement, whose goal is the creation of a communist society, a socioeconomic order centered around common ownership of the means of production, distribution, and exchange that allocates products to everyone in the society based on need. A communist society would entail the absence of private property and social classes, and ultimately money and the state (or nation state).
Yalta ConferenceThe Yalta Conference, held 4–11 February 1945, was the World War II meeting of the heads of government of the United States, the United Kingdom and the Soviet Union to discuss the postwar reorganization of Germany and Europe. The three states were represented by President Franklin D. Roosevelt, Prime Minister Winston Churchill, and General Secretary Joseph Stalin. The conference was held near Yalta in Crimea, Soviet Union, within the Livadia, Yusupov, and Vorontsov palaces.
