Georgios Papandreou

Papandreou founded the Center Union party, a centrist coalition that opposed the conservative National Radical Union. The party became the main opposition force in Greece, advocating for democratic reforms and social justice.

Papandreou won the 1963 elections and became Prime Minister. His government pursued progressive policies, including educational reform, expansion of social services, and a more independent foreign policy, challenging the traditional establishment.

Papandreou clashed with King Constantine II over control of the military, leading to the 'Apostasia' (Apostasy) crisis. The king dismissed Papandreou in July 1965, triggering a period of political instability that culminated in the 1967 coup.

After the 1967 coup, Papandreou was placed under house arrest by the military junta. He remained under surveillance until his death in 1968, becoming a symbol of resistance against the dictatorship.
