The purpose of the current study is to discuss the unification of East and West Germany based on the division of Germany into four parts and the division of Berlin into four parts by the four winning nations, the construction of Berlin Wall by the Soviet Union and East Germany, and the destruction of Berlin Wall by the people of East Germany for Freedom of Travel Open. The methodology was Hegel’s dialectic of These → Antithese → Synthese on the construction and destruction of Berlin Wall which has been at issue by the four winning nations and the two Germanies. In sum, ⓛ These is the four winning nations’ intention to dominate the powers by dividing Germany into east and west and Berlin in half as a result of pre-war talk, ② Antithese is the construction of Berlin Wall by the Soviet Union and East Germany to break the international order and maintain communism, and ③ Synthese is the unintended destruction of Berlin Wall through Aufheben when the people of East Germany’s candle protest as a part of the democratic movement beyond migration and deviation and G. Schabowski’s mistaken remark to open the national borders ‘immediately, without delay’ at a press conference as the spokesperson of East Germany’s SED operated as ‘negation of negation.’ The four winning nations led by the U.S. and the Soviet Union intended to divide Germany to maintain the international powers, but the Soviet Union and East Germany constructed the Berlin Wall to reinforce their own communist systems. However, the Berlin Wall was destroyed by the liberation of people of East Germany for liberal traveling between East and West Germanies and opening of borders and the East German authority’s ambiguous attitude toward the opening of borders. As the destruction of Berlin Wall triggered the unification of Germany, the settlement of German people and unification of Germany would be a fact that supports the dialectic logic that the division of Germany could not persist.
