1. Germany was forced to pay nearly half a trillion USD (in todays money) in reparations
2. Germany's Rhineland in the west was to be occupied by the allies so they couldn't invade France
3. Germany could only have a tiny military, with essentially no navy or air force
4. Germany needed to accept full responsibility for the war
5. Germany loses all of its colonies in Africa, Asia, and the pacific, and much of its valuable eastern land is given to Poland.
