The Munich Agreement (1938)

British Prime Minister Neville Chamberlain, French Premier Édouard Daladier, Italian dictator Benito Mussolini, and German Chancellor Adolf Hitler met in Munich to resolve the Sudetenland crisis. The agreement allowed Germany to annex the Sudetenland from Czechoslovakia, but failed to prevent World War II, which began less than a year later.
Three Mile Island Nuclear Accident (1979)

A partial meltdown of the nuclear reactor core led to the release of radioactive gases and required extensive cleanup efforts. This accident significantly changed the nuclear power industry in the United States and led to new safety regulations and procedures that are still in place today.
