The Munich Agreement was a settlement permitting Nazi Germany's annexation of portions of Czechoslovakia along the country's borders mainly inhabited by German speakers, for which a new territorial designation "Sudetenland" was coined. The agreement was signed in the early hours of 30 September 1938 (but dated 29 September) after being negotiated at a conference held in Munich, Germany, among the major powers of Europe, excluding the Soviet Union. Today, it is widely regarded as a failed act of appeasement toward Germany. The purpose of the conference was to discuss the future of the Sudetenland in the face of ethnic demands made by Adolf Hitler. The agreement was signed by Germany, France, the United Kingdom, and Italy. Sudetenland was of immense strategic importance to Czechoslovakia, as most of its border defenses, and banks were situated there, as well as heavy industrial districts. Part of the borderland was invaded and annexed by Poland.
Because the state of Czechoslovakia was not invited to the conference, it considered itself to have been betrayed by the United Kingdom and France, so Czechs and Slovaks call the Munich Agreement the Munich Diktat (Czech: Mnichovský diktát; Slovak: Mníchovský diktát). The phrase "Munich Betrayal" (Czech: Mnichovská zrada; Slovak: Mníchovská zrada) is also used because the military alliance Czechoslovakia had with France and Britain proved useless and also known because of the phrase "About us, without us!" This phrase is most hurtful for people of Czechoslovakia (Czech republic, Slovakia and Subcarpathian Ruthenia). Today the document is typically referred to simply as the Munich Pact (Mnichovská dohoda).
