World War II: The 1st Ukrainian Front liberates Kyiv from German occupation.

World War II or the Second World War was a global conflict between two coalitions: the Allies and the Axis powers. Nearly all of the world's countries participated, with many nations mobilising all resources in pursuit of total war. Tanks and aircraft played major roles, enabling the strategic bombing of cities and delivery of the first and only nuclear weapons ever used in war. World War II is the deadliest conflict in history, causing the death of 70 to 85 million people, more than half of whom were civilians. Millions died in genocides, including the Holocaust, and by massacres, starvation, and disease. After the Allied victory, Germany, Austria, Japan, and Korea were occupied, and German and Japanese leaders were tried for war crimes.

The 1st Ukrainian Front, previously the Voronezh Front, was a major formation of the Red Army during World War II, being equivalent to a Western army group. They took part in the capture of Berlin, the capital of Nazi Germany.

The Second Battle of Kiev was a part of a much wider Soviet offensive in Ukraine known as the Battle of the Dnieper involving three strategic operations by the Soviet Red Army and its Czechoslovak units and one operational counterattack by the Wehrmacht, which took place between 4 November and 22 December 1943.

The Reichskommissariat Ukraine was an administrative entity of the Reich Ministry for the Occupied Eastern Territories of Nazi Germany from 1941 to 1944. It served as the German civilian occupation regime in the Ukrainian SSR, and parts of the Byelorussian SSR, Russian SFSR, and eastern Poland during the Eastern Front of World War II.
