Thankfully, the world hasn’t had to face another conflict on the catastrophic scale of World War II. While eight decades have now passed, however, repercussions continue to reverberate around the world today. This is in part due to the unbelievable number of casualties, both soldier and civilian. The United States, for example, suffered 418,500 casualties, with another 418,500 lives lost. However, these numbers pale in comparison to the numbers lost by many other nations during the war.

Over 75 million people died over the course of World War II, making it the bloodiest conflict in the history of the world. Soldiers laid down their lives in service of their countries with the hope of making a better world for generations to come. The peace that came from this war has largely held, and while there may be conflicts ongoing around the world — such as in Israel or Ukraine — these tend to be localized and not even close to the scale that was World War II. (These are World War II’s biggest battles.)

Although most conflicts took place in the European and Pacific Theaters, WWII’s battles were widespread fighting across the globe. Countries like New Zealand and South Africa also saw this conflict reach them in some form or fashion. (This country mobilized the most troops during WWII.)

Here 24/7 Wall St. is taking a closer look at the casualties from World War II. To identify the countries with the most casualties in World War II, 24/7 Wall St. reviewed WWII casualty statistics from World War 2 Facts, an online database of WWII battles. We ranked countries based on total casualties. We included supplemental information regarding military deaths for each country as well as civilian deaths.
