Why France join the Allies in World War 2?

1. Treaty of Versailles: France had a strong desire for revenge against Germany, which had defeated it in the Franco-Prussian War and imposed harsh terms on France in the Treaty of Versailles. The treaty had left France feeling humiliated and resentful, and many French people believed that Germany was still a threat to their nation.

2. Nazi Aggression: France was deeply concerned about the growing power and aggression of Nazi Germany under Adolf Hitler. Hitler had annexed Austria and Czechoslovakia in the months leading up to the war, and he was making clear his ambitions to expand Germany's territory further. France feared that it would be the next target of Hitler's aggression.

3. Mutual Defense Pacts: France had mutual defense treaties with Poland and Czechoslovakia. When Germany invaded Poland in September 1939, France was bound to come to Poland's aid. This meant that France was now at war with Germany.

4. Appeasement: France had initially pursued a policy of appeasement towards Germany, in an attempt to avoid war. However, Hitler's continued aggressive actions convinced the French government that appeasement was no longer possible. France was determined to stand up to Germany and defend its interests.

5. Support for Democracy: France was a democratic nation, and it saw Germany as a threat to democracy and freedom. France was committed to defending democratic values and preventing the spread of fascism across Europe.
