1. Territorial Losses: Germany lost significant territories as a result of the treaty. Alsace-Lorraine was returned to France, Eupen-Malmédy to Belgium, North Schleswig to Denmark, and West Prussia, Posen, and Upper Silesia to Poland. Germany also lost all of its overseas colonies. These territorial losses amounted to about 13% of Germany's pre-war territory and left many ethnic Germans living outside the borders of Germany.
2. Reparations: Germany was required to pay reparations to the Allied Powers as compensation for the damage caused during the war. The total amount of reparations was set at 132 billion gold marks (approximately $33 billion), which was to be paid over a period of 30 years. The burden of reparations was heavy and contributed to economic instability and social unrest in Germany.
3. Military Restrictions: Germany's military was severely restricted by the treaty. The German army was limited to 100,000 men, and the air force and submarines were abolished. Germany was also prohibited from importing or manufacturing certain types of weapons and from having a general staff. These restrictions aimed to prevent Germany from regaining its military power and starting another war.
4. War Guilt Clause: Article 231 of the treaty, known as the "War Guilt Clause," placed the sole responsibility for the outbreak of World War I on Germany. This provision was widely resented in Germany and fueled nationalist sentiments. It became a rallying point for those who felt that Germany had been unfairly blamed and punished for the war.
