Following Border Changes Through Major Historical Events
Post-World War I Border Transformations
The Treaty of Versailles in 1919 dramatically reshaped Europe’s political landscape after World War I. The Austro-Hungarian Empire dissolved into multiple independent nations including Austria Hungary Czech Republic Slovakia and parts of Yugoslavia. Germany lost 13% of its pre-war territory with Alsace-Lorraine returning to France while Poland gained access to the Baltic Sea through the Polish Corridor. The Ottoman Empire’s dissolution led to the creation of new states in the Middle East including Iraq Syria and Lebanon under British and French mandates.
Cold War Era Political Divisions
The Iron Curtain split Europe into distinct Eastern and Western spheres of influence after World War II. East Germany Poland Hungary Czechoslovakia Bulgaria Romania and part of Germany fell under Soviet control forming the Eastern Bloc. The Berlin Wall built in 1961 became the most visible symbol of this division cutting West Berlin off from East Germany. The formation of NATO in 1949 and the Warsaw Pact in 1955 further solidified these geopolitical boundaries marking clear ideological territories on Cold War maps that persisted until 1989.
