Answer:
Just estimations
Step-by-step explanation:
The exact number of casualties from all the wars in history is not known, but it is estimated to be in the hundreds of millions. The number of casualties from specific wars varies greatly and can be difficult to accurately determine, but some of the deadliest wars in history include World War II, World War I, the Mongol Conquests, and the Thirty Years' War. The ongoing impact of war on civilian populations, such as displacement and loss of resources, can also have long-lasting effects on communities.
