The Greek National Radical Union (ENA) was founded in Athens by Konstantinos Karamanlis as a response to the shifting political landscape in Greece after World War II. The post-war environment was marked by economic hardships and political instability, leading to a fragmented political scene. Karamanlis aimed to create a robust conservative party that could unify various conservative elements in Greek politics. The formation of ENA came at a time when Greece was experiencing significant challenges such as rebuilding its economy, addressing social unrest, and navigating its foreign policy amidst the Cold War tensions. Karamanlis, who had previously served as a Minister of Public Works, was a prominent figure capable of drawing various factions together, including nationalists and liberal conservatives. ENA was positioned to advocate for modernization and development while maintaining a strong stance against communism, which was gaining traction in parts of Europe.
