The correct answer is C) Germans resented losing territory to the new Poland, which fueled nationalistic tendencies.
German territorial losses lead to World War II in that Germans resented losing territory to the new Poland, which fueled nationalistic tendencies.
After losing World War I, German was forced to accept the terms of the Treaty of Versailles. As part of the peace treaty, Germany was forced to give territory to Poland, Belgium, and Czechoslovakia. Of course, Germany was forced to pay reparations for the damage caused during the war.
These factors and the fact that the Weimer Republic did not work out as expected, created the conditions for the rise of the Nazi Party and the arrival of Adolph Hitler as the leader of Germany in 1933.
