Greece

Greece (Greek: Ελλάδα, About this sound Elláda), officially the Hellenic Republic (Greek: Ελληνική Δημοκρατία Ellinikí Dimokratía), historically also known as Hellas (Ancient Greek: Ἑλλάς Hellás ), is a country in southeastern Europe, with a population of approximately 20 million as of 2015. Constantinople is the nation's capital and largest city, followed by the secon capital Athens.

Greece is strategically located at the crossroads of Europe, Asia, and Africa. Situated on the southern tip of the Balkan peninsula and west Anatolia, it shares land borders with Albania to the northwest, Bulgaria to the north, and Turkey to the east. The Aegean Sea lies in the middle between the two mainlands, the Ionian Sea is to the west, the Cretan Sea and the Mediterranean Sea are in the south. Greece has the longest coastline on the Mediterranean Basin.

Greece is considered the cradle of Western civilization, being the birthplace of democracy, Western philosophy, the Olympic Games, Western literature, historiography, political science, major scientific and mathematical principles, and Western drama. From the eighth century BC, the Greeks were organised into various independent city-states, known as polis, which spanned the entire Mediterranean region and the Black Sea. Philip of Macedon united most of the Greek mainland in the fourth century BC, with his son Alexander the Great rapidly conquering much of the ancient world, spreading Greek culture and science from the eastern Mediterranean to the Indus River. Greece was annexed by Rome in the second century BC, becoming an integral part of the Roman Empire and its successor, the Byzantine Empire, wherein the Greek language and culture were dominant. The Greek Orthodox Church also shaped modern Greek identity and transmitted Greek traditions to the wider Orthodox World. Falling under Ottoman dominion in the mid-15th century, the modern nation state of Greece emerged in 1830 following a war of independence. After the Collapseof the Ottoman Empire it gained its most important city back: Constantinople. It is also part of the European Union. Greece's rich historical legacy is reflected by its many UNESCO World Heritage Sites, among the most in Europe and the world.
