The agreement authorizing the annexation of the Sudetenland by Germany was signed on 29 September 1938. Attitudes in some places have been the subject of a referendum. Within four weeks of the signing of the agreement, the Czechoslovakian government was to release from its military and police forces all Sudeten Germans who wished to be released and all German prisoners from the Sudetenland. Six months after the signing of the Munich Agreement, Hitler reversed his commitments and invaded all of Czechoslovakia. The war was on its way. The Manchester Guardian covered every corner of history, from the details of the deal Chamberlain, which appeared on the balcony of Buckingham Palace, to unease among other nations. One editorial found that the sheet of paper he was waving on his return to Britain was almost worthless. The economic consequences of the Munich agreement will certainly be very severe for Czechoslovakia. The loss of industries, railwayheads, knots, etc., cannot help but cause a sharp loss of trade and unemployment.
There is no doubt that Czechoslovakia becomes the object of quasi-colonial exploitation for Germany. The agreement was signed between Germany, France, Italy and Great Britain from 29 to 30 September 1938. Hitler`s appeasement in the attempt to preserve peace in Europe was strongly supported by the British Prime Minister at the time, Neville Chamberlain. Returning from Munich, Chamberlain signalled the document signed by Hitler and called it a declaration of «peace with honour.» In exchange for European peace, the sudetenland was able to be annexed by the Germans. On 29 and 30 September 1938, an emergency meeting of the major European powers was held in Munich – without Czechoslovakia or the Soviet Union, allied with France and Czechoslovakia. An agreement was quickly reached on Hitler`s terms. It was signed by the leaders of Germany, France, Great Britain and Italy. On the military front, the Sudetenland was of strategic importance to Czechoslovakia, as most of its border defences were there to protect themselves from a German attack. The agreement between the four powers was signed with low intensity in the context of an undeclared German-Czechoslovak war, which had begun on 17 September 1938. Meanwhile, after 23 September 1938, Poland transferred its military units to the common border with Czechoslovakia.  Czechoslovakia bowed to diplomatic pressure from France and Great Britain and decided on 30 September to cede Germany to Munich conditions.
Fearing a possible loss of Zaolzie to Germany, Poland issued an ultimatum to Zaolzie, with a majority of Polish ethnic groups, which Germany had accepted in advance and accepted Czechoslovakia on 1 October.  As the threats of Germany and a European war became increasingly evident, opinions changed.
