The Korean War was a brutal campaign. Thousands died and millions were affected by the hostilities that took place on the Korean Peninsula. Below are some figures that offer a relative sense of the impact of the war compared to other East Asian civil wars.
While the Korean War is known for the American military intervention that took place in 1950 after the North Koreans attacked South Korea, the war was first and foremost a war between Koreans. Some notable East Asian conflicts that began as internal conflicts were only further exasperated when the two super powers—the U.S. and Soviet Union—became involved as well. Below, we have compared the impact of civil war on other East Countries to the Korea. The statistics below show the viewer that the scale of the Korean War qualifies it as a deadly war, and was not a “limited war” or “police action” that many government officials have called it in the past.
This line graph presents the same information as the bar graph above, (without Cambodia) but is a clearer presentation of the amount of civilians and military forces killed.
The following line graph presents the estimated number of refugees from Korea, Vietnam, and Cambodia as a result of the wars in these countries.
