The exact number of people who died in the Hundred Years War is difficult to determine due to the lack of precise records from that time. However, historians estimate that the war, which lasted from 1337 to 1453, resulted in the deaths of approximately 2 to 3 million people. This includes soldiers who died in battle, as well as civilians who perished due to the widespread devastation, famine, and disease caused by the prolonged conflict. The war had a significant impact on the populations of both England and France, leading to substantial demographic changes and long-term social and economic consequences.
