Treaty Conditions
Germany suffered massive territorial losses under the treaty. The Rhineland (the territory between Germany and France) was completely demilitarised, creating a buffer zone. Alsace-Lorraine, a disputed territory, was returned to France after being under German control since 1871.
All of Germany's colonies were stripped away and distributed to other nations, with France, Britain, and the USA keeping the most valuable ones. This ended Germany's brief period as a colonial power and reduced their global influence.
Germany's military was deliberately weakened. Their army was limited to just 100,000 men (a tiny fraction of their wartime strength), only 6 battleships were allowed, and merely 6 aircraft could be maintained. This effectively ended Germany's status as a major military power.
The treaty also forced Germany to accept the War Guilt Clause, requiring them to take responsibility for causing the entire conflict, which many Germans found deeply humiliating.
