The Eastern Front of World War II was a theatre of World War II between the European Axis powers and co-belligerent Finland against the Soviet Union, Poland, and some other Allies which encompassed Northern, Southern and Eastern Europe from 22 June 1941 to 9 May 1945. It was known by many different names depending on the nation, notably the Great Patriotic War (Russian: Великая Отечественная Война) in the former Soviet Union, while known in Germany as the Eastern Front (German: die Ostfront), the Eastern Campaign (German: der Ostfeldzug) or the Russian Campaign (German: der Rußlandfeldzug).

The battles on the Eastern Front constituted the largest military confrontation in history. They were characterized by unprecedented ferocity, wholesale destruction, mass deportations, and immense loss of life variously due to combat, starvation, exposure, disease, and massacres. The Eastern Front, as the site of nearly all extermination camps, death marches, ghettos, and the majority of pogroms, was central to the Holocaust. Of the estimated 70 million deaths attributed to World War II, over 30 million, many of them civilians, died on the Eastern Front. The Eastern Front was decisive in determining the outcome of World War II, eventually serving as the main reason for Germany's defeat. It resulted in the destruction of the Third Reich, the partition of Germany for nearly half a century and the rise of the Soviet Union as a military and industrial superpower.

The French invasion of Russia of 1812 (also known as the Patriotic War of 1812, Russian: Отечественная война 1812 года) was a turning point in the Napoleonic Wars. It reduced the French and allied invasion forces (the Grande Armée) to a tiny fraction of their initial strength and triggered a major shift in European politics as it dramatically weakened French hegemony in Europe. The reputation of Napoleon as an undefeated military genius was severely shaken, while the French Empire's former allies, at first Prussia and then the Austrian Empire, broke their alliance with France and switched camps, which triggered the War of the Sixth Coalition.

The campaign began on 24 June 1812, when Napoleon's forces crossed the Neman River. Napoleon aimed to compel Emperor of Russia Alexander I to remain in the Continental Blockade of the United Kingdom; an official aim was to remove the threat of a Russian invasion of Poland. Napoleon named the campaign a Second Polish War; the Russian government proclaimed a Patriotic War.

Aram Ilyich Khachaturian (Armenian: Արամ Խաչատրյան; Russian: Ара́м Ильи́ч Хачатуря́н; June 6 [O.S. May 24] 1903 – May 1, 1978) was a prominentSoviet Armenian composer. Khachaturian's works were often influenced by classical Russian music and Armenian folk music. He is most famous for the Adagio of Spartacus and Phrygia from his ballet Spartacus, and for the "Sabre Dance" from his ballet Gayane and the adagio from the same ballet, much used in films since its first use in Stanley Kubrick's 2001: A Space Odyssey.

Aram Ilyich Khachaturian was born in Tiflis, Imperial Russia (now Tbilisi, Georgia) to a poor Armenian family. His father was a bookbinder. In his youth, he was fascinated by the music he heard around him, but at first he did not study music or learn to read it.

In 1920, when Armenia was declared a Soviet republic, Khachaturian joined a propaganda train touring Armenia, populated by Georgian-Armenian artists. The following year he travelled to Moscow to join his brother, the stage director of the Second Moscow Art Theatre. Although he had almost no musical education, Khachaturian showed such great talent that he was admitted to the Gnessin Institute where he studied cello under Sergey Bychkov, and later Andrey Borysyak. In 1925 Mikhail Gnessin started a composition class at the Gnessin Institute, which Khachaturian joined.
