When were the Locarno treaties signed?

The treaties were initialed at Locarno on 16 October and signed in London on 1 December 1925. The principal agreement guaranteed Germany's frontiers with France and Belgium in return for Germany's full restoration to the international community and the withdrawal of Allied occupation forces from the Rhineland, which would subsequently be demilitarized. Germany agreed to arbitration in the event of disputes with Poland and Czechoslovakia, but without an international guarantee of borders as in the west. The treaties alienated France's ally Poland, which sought a guarantee for its territory, and the USSR, which saw the agreements as an attempt to detach Germany from its 1922 understanding with Moscow. Adolf Hitler's Nazi regime tore up the main treaty in March 1936, sending German troops into the Rhineland.
