Information:  - Greece (' ), officially the Hellenic Republic (Greek: ' ), historically also known as Hellas ("" ), is a country in southeastern Europe.  Greece's population is approximately 10.955 million as of 2015. Athens is the nation's capital and largest city, followed by Thessaloniki.  - The National Radical Union ((), "Ethnik Rizospastik Énsis" (ERE)) was a Greek political party formed in 1955 by Konstantinos Karamanlis, mostly out of the Greek Rally party.  - Greek Rally ((), "Ellnikòs 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.  - Athens ("Athína" ) is the capital and largest city of Greece. Athens dominates the Attica region and is one of the world's oldest cities, with its recorded history spanning over 3,400 years, and its earliest human presence starting somewhere between the 11th and 7th millennia BC. Classical Athens was a powerful city-state that emerged in conjunction with the seagoing development of the port of Piraeus, which had been a distinct city prior to its 5th century BC incorporation with Athens. A centre for the arts, learning and philosophy, home of Plato's Academy and Aristotle's Lyceum, it is widely referred to as the cradle of Western civilization and the birthplace of democracy, largely because of its cultural and political impact on the European continent, and in particular the Romans. In modern times, Athens is a large cosmopolitan metropolis and central to economic, financial, industrial, maritime, political and cultural life in Greece. In 2015, Athens was ranked the world's 29th richest city by purchasing power and the 67th most expensive in a UBS study.  - Parliamentary elections were held in Greece on 19 February 1956 .
