BETWEEN THE WORLD WARS
World War I (1916- 1918)

It involved all the world’s great powers which were assembled in two opposing alliances:
– the Allies (France, the British Empire, Russia and later, Japan, Italy and the United States)
– and the Central Powers (Germany, Austria-Hungary, the Ottoman Empire (Turkey)).
Until World War II, it was often called the Great War because it was the most destructive and widespread war the world had ever seen.
It was a war fought in trenches all over Europe.
It was modern war fought with aeroplanes, machine guns and tanks, but the commanders often behaved as if it were a 19th-century war.
They marched their troops across open land to be slaughtered by the machine guns.
The use of poison gas added to the horrors of the war.
Two great battles fought on the Western Front in 1916, the Battle of Verdun the Battle of the Somme alone, claimed nearly two million lives
The effects of WWII
World War I ended in 1918, leading to 38 million deaths, a worldwide economic depression, and political upheavals that set the stage for World War II in 1939.
World War II was a global conflict from 1939 to 1945, triggered by Adolf Hitler's expansionist aims in an unstable Germany.
World War II caused around 60 million deaths worldwide.
The war's end led to the collapse of European imperialism due to weakened political and economic power.
During the 1930s, numerous European intellectuals , fled to America to escape Nazi persecution.
