Europe is a melting pot of diverse cultures, civilizations and amalgamation of various ethnicities. It is a land which faced many catastrophes, high intensity conflicts and wars. Two world wars have been fought on this land. Almost all the major nations participated directly or indirectly at massive scale. Franco-German axis is a term to explain the relations of both the countries in the context of their mutual cooperation and their significant role in contemporary political affairs of Europe. Post war era 1945, congenial atmosphere of synchronization between both the countries replaced three century old French- German hostility. This tandem performed active role not only in the politically integrated European nation but also they played a vital role in the formation of single currency euro as well. Comparatively their functioning is becoming slow but they are still necessary for future of Europe. It is a general impression that the FrancoGerman alliance is facing critical phase, or in other words they are no longer being capable to act as the twin motor of European integration but Euro pe do not have an appropriate replacement. As far as the future of Franco-German relationship or leadership is concerned it acted necessary of European Union’s twin motor in the past but in recent years national interest became more supreme than the interest of European Union as a whole.
