World War II: German forces recaptured Kharkov after four days of house-to-house fighting against Soviet troops, ending the month-long Third Battle of Kharkov.

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.

Kharkiv, also known as Kharkov, is the second-largest city in Ukraine. Located in the northeast of the country, it is the largest city of the historic region of Sloboda Ukraine. Kharkiv is the administrative centre of Kharkiv Oblast and Kharkiv Raion. Prior to the Russian invasion of Ukraine in early 2022, it had an estimated population of 1,421,125.

The Third Battle of Kharkov was a series of battles on the Eastern Front of World War II, undertaken by Nazi Germany's Army Group South against the Soviet Red Army, around the city of Kharkov between 19 February and 15 March 1943. Known to the German side as the Donets Campaign, and in the Soviet Union as the Donbass and Kharkov operations, the German counterstrike led to the recapture of the cities of Kharkov and Belgorod.
