Germany's payment of reparations
1. Germany paid her first reparation payment in 1921
2. Germany couldn't afford the 1922 payment
3. France and Belgium invaded the Ruhr, Germany's main industrial area, to take goods
4. The Germans reacted with passive resistance, going on strike and refusing to make the goods that the French and Belgians wanted, sabotaging factories and flooding mines
5. The French and Belgians reacted with violence, shooting some Germans and expelling some others
6. The Weimar Government supported the strikers by printing more money to pay them so that they could afford to keep striking
