25 Lesser-Known But Horrific War Crimes That Might Shock You

Posted by , Updated on May 22, 2024

An examination of the timeline of human history shows that our past is filled with conflicts and wars triggered by a variety of reasons. Generally, these organized conflicts are initiated by governments and political leaders, not ordinary people. Often, these clashes stem from the greed of individuals seeking control over specific territories and their resources. Although war is considered the most severe method of resolving disputes between factions, the atrocities committed during war can be even more horrifying than the conflict itself. As a result, the concept of war crimes emerged in the late nineteenth century, along with the formal establishment of international law governing conflicts between sovereign states.

There have been many war crimes since the term first began to be officially used, and it’s truly terrifying to think how many more there would be if the concept existed from the start of military history. Some of the deadliest war crimes include the violent colonization of the Americas, the Holocaust, and the Holodomor, but we are afraid these are only some of the most well-known and not just solitary incidents. These are 25 Lesser-Known But Horrific War Crimes That Might Shock You.
