How did Hitler use the concept of German nationalism to provoke a war in Europe?

Hitler used the concept of nationalism to join all the German people from different nations in its neighboring countries.

Explanation:

After the first World War, Germany forced to sign the Treaty of Versailles, which somewhat shattered the country in every aspect. The German Empire was broken in portions and formed into other countries.

Some of these countries became Czechoslovakia (Sudetenland), Silesia, Poland, etc. These areas had a large German population in them, and they somewhat lost their jobs. In the 1930's Hitler used the term nationalism in Eastern Europe to join all Germans together with land, which once was part of the German Empire. He invaded Czechoslovakia and towards western portions of Poland. Nazi used the slogan called Ein Volk, ein Reich, ein Führer.

Ultimately all this did not conclude as a good sign for the British and France, and at last, they declared war on Nazi Germany.

The German people saw it as a restoration of their former glory when Hitler invaded Poland and justifying the act as the emancipation of the Germans living in Poland.

Explanation:

Hitler transformed German nationalism into ethnic and cultural nationalism. The German people were made to believe that the Aryan race bloodline was superior and exclusive. He used the media to spread propaganda for getting German people to embrace his philosophies. He sparked an enthusiastic nationalism in the germans that led Germany to take over Sudetenland which was once a German territory but now a part of Poland where many Germans still lived. The Poles and their government had allegedly mistreated these German people, possibly because of bad feelings towards Germans from the first world war.
