Most of Europe celebrated the Munich agreement, which was presented as a way to prevent a major war on the continent. The four powers agreed to the German annexation of the Czechoslovak borderland areas named the Sudetenland, where more than three million people, mainly ethnic Germans, lived. Adolf Hitler announced that it was his last territorial claim in Northern Europe.
Today, the Munich Agreement is widely regarded as a failed act of appeasement, and the term has become "a byword for the futility of appeasing expansionist totalitarian states."
The Second Czechoslovak Republic (Czech: Druhá československá republika, Slovak: Druhá česko-slovenská republika) existed for 169 days, between 30 September 1938 and 15 March 1939. It was composed of Bohemia, Moravia, Silesia and the autonomous regions of Slovakia and Subcarpathian Rus', the latter being renamed Carpathian Ukraine on 30 December 1938.
