Fall Grün (Czechoslovakia)

In World War II, Operation Grün was the Nazi invasion of Czechoslovakia which began on 14 March, 1938.

The areas of Czechoslovakia with a majority of ethnic Germans were peacefully ceded to Germany on 1 October, 1938 at the infamous Munich Conference. The Czechs were therefore without their formidable border defenses. When the Germans invaded, the Czechs were abandoned by their British and French allies. They surrendered with only local resistance.

The Germans annexed the Czech areas and created a puppet Slovak Republic in the east. The destruction of Czechoslovakia outflanked Poland to the north in much the same way as the annexation of Austria had outflanked the Czechs themselves.

Czechoslovakia was recreated after World War II but has since divided itself into Slovakia and the Czech Republic.
