Victory in Europe Day which is generally known as VE Day, marks the day Nazi Germany unconditionally surrendered to the allies in May 1945.
As Statista's Niall McCarthy notes, debate still rages among younger generations as to which allied nation played the most important role in defeating the Germans during the war.
The USSR undoubtedly made the biggest human sacrifice with a quarter of the entire Soviet population killed or wounded during the conflict. In total, an estimated 27 million Soviets are thought to have perished. The U.S. had just over 400,000 military deaths (including the war in the Pacific) while the UK had approximately 384,000 (also including deaths in combat with Japan).
Despite the massive Soviet casualty figures, some believe their decisive contribution to the war effort was only achievable through lend-lease weaponry from the UK and US.
Others point out that Russian ingenuity, industrial capacity and innovative equipment such as the T-34 tank were the main reasons the allies won the war.
Some also say that USAAF and RAF bombing destroyed Germany's ability to wage war effectively, providing the greatest contribution to victory.
YouGov conducted a poll to find out what the current generation think.
