reversed with eighty percent voting for Germany and twenty percent for Denmark. In this vote, each municipality decided its own future, and German majorities prevailed everywhere. In light of these results, the government of Prime Minister Carl Theodor Zahle determined that reunification with Northern Schleswig could go forward, while Central Schleswig would remain under German control. Many Danish nationalists felt that at least the city of Flensburg, in Central Schleswig, should be returned to Denmark regardless of the plebiscite's results, due to the sizeable Danish minority there and a general desire to see Germany permanently weakened in the future. Christian X agreed with these sentiments, and ordered Prime Minister Zahle to include Flensburg in the re-unification process. As Denmark had been operating as a parliamentary democracy since the Cabinet of Deuntzer in 1901, Zahle felt he was under no obligation to comply. He refused the order and resigned several days later after a heated exchange with the King. Subsequently, Christian X dismissed the rest of the cabinet and replaced it with a de facto conservative caretaker cabinet. The dismissal caused demonstrations and an almost revolutionary atmosphere in Denmark, and for several days the future of the monarchy seemed very much in doubt. In light of this, negotiations were opened between the King and members of the Social Democrats. Faced with the potential overthrow of the Danish Crown, Christian X stood down and dismissed his own government, installing a compromise cabinet until elections could be held later that year. To date, this is the last time a reigning Danish monarch has attempted to take political action without the full support of parliament. Following the crisis, Christian X bowed fully to his drastically reduced status, and spent the last quarter-century of his rule as a model constitutional monarch. World War II On 9 April 1940 at 4 am Nazi Germany invaded Denmark in a surprise attack, overwhelming Denmark's Army and Navy and destroying the Danish Army Air Corps. Christian X quickly realized that Denmark was in an impossible position. Its territory and population were far too small to hold out against Germany for any sustained period of time. Its flat land would have resulted in it being easily overrun by German panzers; Jutland, for instance, would have been overrun in short order by a panzer attack from Schleswig-Holstein immediately to the south. Unlike its Nordic neighbours, Denmark had no mountain ranges from
