Under the Versailles Settlement, Czechoslovakia was created with the territory of the Czech part more or less corresponding to the Czech Crown lands as they had existed within the Austria-Hungary and before. It included Bohemia, Moravia, and Slovakia and had border areas with a majority German population known as the Sudetenland and areas with significant numbers of other ethnic minorities (notably Hungarians, Poles, and Ruthenes). In April 1938, Sudeten Nazis, led by Konrad Henlein, agitated for autonomy and then threatened, in Henlein's words, "direct action to bring the Sudeten Germans within the frontiers of the Reich". An international crisis ensued.
