Greek Rally ( (ΕΣ), Ellīnikòs Synagermós (ES)) was a right-wing political party in Greece. Founded on 6 August 1951 by former field marshal Alexandros Papagos, the party encompassed a broad spectrum of the royalist conservative elements in Greek society and was modelled on the Charles de Gaulle's Rassemblement du Peuple Français (RPF). Throughout the years, the Greek right had become splintered. Papagos' new party managed to attract considerable support, and the Populist Uniting Party (led by Panagiotis Kanellopoulos and Stephanos Stephanopoulos) and the New Party (led by Spiros Markezinis) dissolved and merged with the Greek Rally. Later on, a large portion of the People's Party, the major right-wing party of the prewar era, defected to the Greek Rally; among the prominent defectors was Konstantinos Karamanlis.
