What was Korea's involvement in World War 1?

Answer 1

Some would argue that they didn't declare war and they remained neutral, because Korea was controlled by Japan and didn't have any form of government until 1919 it meant that once Japan went to war, any provinces under Japanese rule effectively went to war, just like the British Empire.
