The Partition of France was a process of breaking up the member-states of the French Empire throughout the fall of 1945 and the spring of 1946 by the Allies as per the Glasgow Agreement. The three main powers of the Allies - the British, the Germans and the Swedes - agreed to divide France up into three occupation zones. In the northeast would be the Swedish occupation zone of Holland-Belgium, the smallest of the three; in the south and east the German occupation zone of Burgundy; and in the north, the British occupation zone of Normandy. Paris would be divided into three occupation zones.
Eventually, in terms of the Cold War, South Paris became the German stronghold, while North Paris became the British stronghold and the capital of the People's Democratic Republic of France. Meanwhile, the French Fourth Republic was established in the south, with its capital at Marseille, and Holland-Belgium eventually split into two independent republics, both aligned with TATO.
France, like all of Western Europe, was a central part of the standoff between Britain and Germany during the Cold War. The South enjoyed robust growth during this period, unlike North France, which like many British client states suffered economically. In 1991, after the fall of the Parisian Wall and the reunification of France, Paris became the capital of a reunited France, while Belgium and Holland maintained their postwar independence.
