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.
Holocaust victimsHolocaust victims were people targeted by the government of Nazi Germany based on their ethnicity, religion, political beliefs, and/or sexual orientation. The institutionalized practice by the Nazis of singling out and persecuting people resulted in the Holocaust, which began with legalized social discrimination against specific groups, involuntary hospitalization, euthanasia, and forced sterilization of persons considered physically or mentally unfit for society.
Romani HolocaustThe Romani Holocaust or the Romani genocide—also known as the Porajmos (Romani pronunciation: phoɽajˈmos, meaning "the Devouring"), the Pharrajimos (meaning "the Cutting up", "the Fragmentation", "the Destruction"), and the Samudaripen ("Mass killing")—was the planned effort by Nazi Germany and its World War II allies and collaborators to commit ethnic cleansing and eventually genocide against European Roma and Sinti peoples during the Holocaust era.
WehrmachtThe Wehrmacht (ˈveːɐ̯maxt, defence force) were the unified armed forces of Nazi Germany from 1935 to 1945. It consisted of the Heer (army), the Kriegsmarine (navy) and the Luftwaffe (air force). The designation "Wehrmacht" replaced the previously used term Reichswehr and was the manifestation of the Nazi regime's efforts to rearm Germany to a greater extent than the Treaty of Versailles permitted.
AustriaAustria (Österreich), formally the Republic of Austria (Republik Österreich), is a landlocked country in Central Europe, lying in the Eastern Alps. It is a federation of nine provinces, one of which is the capital, Vienna, the most populous city and province. Austria is bordered by Germany to the northwest, Czechia to the north, Slovakia to the northeast, Hungary to the east, Slovenia and Italy to the south, and Switzerland and Liechtenstein to the west. The country occupies an area of and has a population of 9 million.
European theatre of World War IIThe European theater of World War II was one of the two main theaters of combat during World War II. It saw heavy fighting across Europe for almost six years, starting with Germany's invasion of Poland on 1 September 1939 and ending with the Western Allies conquering most of Western Europe, the Soviet Union conquering most of Eastern Europe including the German capital Berlin and Germany's unconditional surrender on 8 May 1945 although fighting continued elsewhere in Europe until 25 May.
Adolf HitlerAdolf Hitler (ˈaːdɔlf ˈhɪtlɐ; 20 April 1889 - 30 April 1945) was an Austrian-born German politician who was the dictator of Germany from 1933 until his suicide in 1945. He rose to power as the leader of the Nazi Party, becoming the chancellor in 1933 and then taking the title of Führer und Reichskanzler in 1934. During his dictatorship, he initiated World War II in Europe by invading Poland on 1 September 1939. He was closely involved in military operations throughout the war and was central to the perpetration of the Holocaust, the genocide of about six million Jews and millions of other victims.
Occupation of Czechoslovakia (1938–1945)The military occupation of Czechoslovakia by Nazi Germany began with the German annexation of the Sudetenland in 1938, continued with the creation of the Protectorate of Bohemia and Moravia, and by the end of 1944 extended to all parts of Czechoslovakia. Following the Anschluss of Austria in March 1938 and the Munich Agreement in September of that same year, Adolf Hitler annexed the Sudetenland from Czechoslovakia. The loss of the Sudetenland was detrimental to the defense of Czechoslovakia, as the extensive Czechoslovak border fortifications were also located in the same area.
German war crimesThe governments of the German Empire and Nazi Germany (under Adolf Hitler) ordered, organized, and condoned a substantial number of war crimes, first in the Herero and Namaqua genocide and then in the First and Second World Wars. The most notable of these is the Holocaust, in which millions of European Jewish, Polish, and Romani people were systematically abused, deported, and murdered. Millions of civilians and prisoners of war also died as a result of German abuses, mistreatment, and deliberate starvation policies in those two conflicts.
Japanese war crimesThe Empire of Japan committed war crimes and crimes against humanity in many Asian-Pacific countries during the period of Japanese imperialism, primarily during the Second Sino-Japanese and Pacific Wars. These incidents have been described as "the Asian Holocaust". Some war crimes were committed by Japanese military personnel during the late 19th century, but most were committed during the first part of the Shōwa era, the name given to the reign of Emperor Hirohito.
