Greece

Greece, officially the Hellenic Republic, is a country in Southeast Europe. Located on the southern tip of the Balkan peninsula, it shares land borders with Albania to the northwest, North Macedonia and Bulgaria to the north, and Turkey to the east. The Aegean Sea lies to the east of the mainland, the Ionian Sea to the west, and the Sea of Crete and the Mediterranean Sea to the south. Greece has the longest coastline on the Mediterranean basin, spanning thousands of islands and nine traditional geographic regions. It has a population of over 10 million. Athens is the nation's capital and largest city, followed by Thessaloniki and Patras.

Greece is considered the cradle of Western civilisation and the birthplace of democracy, Western philosophy, Western literature, historiography, political science, major scientific and mathematical principles, theatre, and the Olympic Games. The Ancient Greeks were organised into independent city-states, or poleis (singular polis), that spanned the Mediterranean and Black seas. Philip II of Macedon united most of present-day Greece in the fourth century BC, with his son Alexander the Great conquering much of the known ancient world from the Near East to northwestern India. The subsequent Hellenistic period saw the height of Greek culture and influence in antiquity. Greece was annexed by Rome in the second century BC and became an integral part of the Roman Empire and its continuation, the Byzantine Empire, where Greek culture and language were dominant. The Greek Orthodox Church helped shape modern Greek identity and transmitted Greek traditions to the wider Orthodox world.

After the Fourth Crusade in 1204, Greece and the rest of the Byzantine empire were fragmented into several Latin and Byzantine successor polities, with most Greek lands finally coming under Ottoman control by the mid-15th century. Following a protracted war of independence in 1821, Greece emerged as a modern nation state in 1830. The Kingdom of Greece pursued territorial expansion during the Balkan Wars (1912–1913) and World War I (1914–1918), until its defeat in the Greco-Turkish War in 1922. A short-lived republic was established in 1924 but faced civil strife and the challenge of resettling refugees from Turkey, culminating in a royalist dictatorship in 1936. Greece endured military occupation during World War II, the subsequent Greek Civil War, and prolonged political instability, leading to a military dictatorship in 1967. The country began transitioning to democracy in 1974, leading to the current parliamentary republic.

Owing to record economic growth from 1950 to 1973, Greece is a developed country with an advanced high-income economy; its high standard of living has been damaged by a decade-long debt crisis that emerged in the wake of the 2008 financial crisis. Shipping and tourism are major economic sectors, with Greece being the ninth most-visited country in the world in 2024. Greece is part of multiple international organisations and forums, being the tenth member to join what is today the European Union in 1981. The country's rich historical legacy is reflected partly by its 20 UNESCO World Heritage Sites.
