The significant civil war that happened just before WW II was the Spanish Civil War.

the world war end peacefully
There was Spanish civil war before World War 2 in which fascists and communists fought on opposite sides and it served as "prototype" to World War 2. But civil war ended before World War 2 started.
World War II
Trinity test happened on the morning of July 16, 1945 just before dawn.
World War I was from 1914 to 1918, US involvement was 1917 to 1918.
The Cold War began after the Second World War ended in Germany and Japan's defeat.
World War I (1914-1918) took place before the Vietnam War (1955-1975).
they lost 8 billion just in war debts.
World War 1 happened first and World War 2 happened second.
World War 1 was not a cold war because of all the people that died the only time that there has been a cold war was after world war 2 and that was before the Korean war happened i hope this helps
