2) How many years between the end of WWI (1918) and the beginning of WWII (1939)?

The Big Three were the three main victorious countries after World War One.

Sometimes they are referred to as the Allied Powers, sometimes the victors and

sometimes the Big Three. They include Britain, France and the United States of

America. Each of these countries had fought alongside each other during the First

World War.

France had been badly damaged during the war, suffering devastation in the

countryside and losing many thousands of soldiers during the conflict. Britain too had

lost many soldiers throughout the war. This would have an impact on their approach

to peace during the Paris Peace Conference. The United States joined the way in

1917, and lost relatively few soldiers when compared to Britain and France.
