The document discusses Czechoslovakia in 1938. It describes how the country's borders were established after World War 1, noting a region called the Sudetenland with 3 million ethnic Germans. While Britain, France and the USSR agreed to help Czechoslovakia if Germany invaded, Hitler convinced them he would not and instead claimed the Czech government was discriminating against Germans. Nazi protests in the Sudetenland increased tensions until world leaders appeased Hitler and pressured Czechoslovakia to give concessions to Germany.
