Greece becomes the first member state to join the European Economic Community by signing the Athens Agreement, which is later suspended in 1967 during the Greek junta.

Greece, officially the Hellenic Republic, is a country of 10 million people on the southern tip of the Balkan peninsula in Southeast Europe. With nine regions and thousands of islands, it has the longest coastline on the Mediterranean. The Ionian Sea is west of the mainland, Albania northwest, and North Macedonia and Bulgaria north. Turkey is east both by land and the Aegean Sea. The capital, Athens, is the largest Greek city, followed by Thessaloniki and Patras.
