Modern Greek in the context of Gemination

Classical Athens, known contemporaneously simply as Athens (Ancient Greek: Ἀθῆναι, Athênai [atʰɛ̂ːnai̯]; Modern Greek: Αθήναι, Athine [aˈθine]), was the major urban centre of the notable polis (city-state) of the same name during the classical period (480–323 BC) of ancient Greece, located in Attica, Greece, leading the Delian League in the Peloponnesian War against Sparta and the Peloponnesian League. Athenian democracy was established in 508 BC under Cleisthenes following the tyranny of Isagoras. This system remained remarkably stable, and with a few brief interruptions, it remained in place for 180 years, until 322 BC (amid the aftermath of the Lamian War). The peak of Athenian hegemony was achieved during the Age of Pericles in the 440s and 430s BC.

In the classical period, Athens was a centre for the arts, learning, and philosophy, and it was the home of Plato's Academy and Aristotle's Lyceum. Athens was also the birthplace of Socrates, Plato, Pericles, Aristophanes, Sophocles, and many other prominent philosophers, writers, and politicians of the ancient world. It is widely referred to as the cradle of Western civilization and as the birthplace of democracy, largely due to the impact of its cultural and political achievements during the 5th and 4th centuries BC on the rest of the then-known European continent.

Polis (pl.: poleis) means 'city' in Ancient Greek. The ancient word polis had socio-political connotations not possessed by modern usage. For example, Modern Greek πόλη (póli), "city", is located within a χώρα (chóra), "country", which is a πατρίδα (patrída) or "native land" for its citizens. In ancient Greece, the polis was the native land; there was no other. It had a constitution and demanded the supreme loyalty of its citizens. Χώρα was only the countryside, not a country. Ancient Greece was not a sovereign country, but was territory occupied by Hellenes, people who claimed as their native language some dialect of Ancient Greek.

Poleis did not only exist within the area of the modern Republic of Greece. A collaborative study carried by the Copenhagen Polis Centre from 1993 to 2003 classified about 1,500 settlements of the Archaic and Classical ancient-Greek-speaking population as poleis. These ranged from the Caucasus to Southern Spain, and from Southern Russia to Northern Egypt, spread over the shores of the Mediterranean and Black Sea. They have been termed a network of micro-states. Many of the settlements still exist; e.g., Marseille, Syracuse, Alexandria, but they are no longer Greek or micro-states, belonging to other countries.

Greek (Modern Greek: ελληνικά, romanized: elliniká [eliniˈka] ; Ancient Greek: ἑλληνική, romanized: hellēnikḗ [helːɛːnikɛ́ː]) is an Indo-European language, constituting an independent Hellenic branch within the Indo-European language family. It is native to the territories that have had populations of Greeks since antiquity: Greece, Cyprus, Egypt, Italy (in Calabria and Salento), southern Albania, and other regions of the Balkans, Caucasus, the Black Sea coast, Asia Minor, and the Eastern Mediterranean. It has the longest documented history of any Indo-European language, spanning at least 3,400 years of written records. Its writing system is the Greek alphabet, which has been used for approximately 2,800 years; previously, Greek was recorded in writing systems such as Linear B and the Cypriot syllabary.

The Greek language holds a very important place in the history of the Western world. Beginning with the epics of Homer, ancient Greek literature includes many works of lasting importance in the European canon. Greek is also the language in which many of the foundational texts in science and philosophy were originally composed. The New Testament of the Christian Bible was also originally written in Greek. Together with the Latin texts and traditions of the Roman world, the Greek texts and Greek societies of antiquity constitute the objects of study of the discipline of Classics.

The Acropolis of Athens (Ancient Greek: ἡ Ἀκρόπολις τῶν Ἀθηνῶν, romanized: hē Akropolis tōn Athēnōn; Modern Greek: Ακρόπολη Αθηνών, romanized: Akrópoli Athinón) is an ancient citadel located on a rocky outcrop above the city of Athens, Greece, and contains the remains of several ancient buildings of great architectural and historical significance, the most famous being the Parthenon. The word Acropolis is from Greek ἄκρον (akron) 'highest point, extremity' and πόλις (polis) 'city'. The term acropolis is generic and there are many other acropoleis in Greece. During ancient times the Acropolis of Athens was also more properly known as Cecropia, after the legendary serpent-man Cecrops, the supposed first Athenian king.

While there is evidence that the hill was inhabited as early as the 4th millennium BC, it was Pericles (c. 495–429 BC) in the fifth century BC who coordinated the construction of the buildings whose present remains are the site's most important ones, including the Parthenon, the Propylaea, the Erechtheion and the Temple of Athena Nike. The Parthenon and the other buildings were seriously damaged during the 1687 siege by the Venetians during the Morean War when gunpowder being stored by the Turkish rulers in the Parthenon was hit by a Venetian bombardment and exploded.

Katharevousa (Greek: Καθαρεύουσα, pronounced [kaθaˈrevusa], literally "purifying [language]") is a conservative form of the Modern Greek language conceived in the late 18th century as both a literary language and a compromise between Ancient Greek and the contemporary vernacular, Demotic Greek. Originally, it was widely used for both literary and official purposes, though sparingly in daily language. In the 20th century, it was increasingly adopted for official and formal purposes, until minister of education Georgios Rallis made Demotic Greek the official language of Greece in 1976, and in 1982 Prime Minister Andreas Papandreou abolished the polytonic system of writing for both Demotic and Katharevousa.

Katharevousa was conceived by the intellectual and revolutionary leader Adamantios Korais (1748–1833). A graduate of the University of Montpellier, Korais spent most of his life as an expatriate in Paris. As a classical scholar credited with both laying the foundations of Modern Greek literature and a major figure in the Greek Enlightenment, he was repelled by Byzantine influence on Greek society as well as that of its successors, and was a fierce critic of the clergy and their alleged subservience to the Ottoman Empire. He held that education was a prerequisite to Greek liberation.

Crete (/kriːt/ KREET; Greek: Κρήτη, Modern: Kríti [ˈkriti], Ancient: Krḗtē [krɛ̌ːtεː]) is the largest and most populous of the Greek islands, the 90th largest island in the world, and the fifth largest island in the Mediterranean Sea, after Sicily, Sardinia, Cyprus, and Corsica. Crete is located approximately 100 km (62 mi) south of the Peloponnese, and about 300 km (190 mi) southwest of Anatolia. Crete has an area of 8,450 km (3,260 sq mi) and a coastline of 1,046 km (650 mi). It bounds the southern border of the Aegean Sea, with the Sea of Crete (or North Cretan Sea) to the north and the Libyan Sea (or South Cretan Sea) to the south. Crete covers 260 km from west to east but is narrow from north to south, spanning three degrees of longitude but only half a degree of latitude.

Crete and its surrounding islands and islets form the Region of Crete (Greek: Περιφέρεια Κρήτης), which is the southernmost of the 13 top-level administrative units of Greece, and the fifth most populous of Greece's regions. Its capital and largest city is Heraklion, located on the island's north shore. As of 2021, the region had a population of 624,408. The Dodecanese are located to the northeast of Crete, while the Cyclades are situated to the north, separated by the Sea of Crete.

Euboea (/juːˈbiːə/ yoo-BEE-ə; Ancient Greek: Εὔβοια, romanized: Eúboia, IPA: [ěu̯boi̯a]), also known by its modern spelling Evia (/ˈɛviə/ EV-ee-ə; Modern Greek: Εύβοια, IPA: [ˈevi.a]), is the second-largest Greek island in area and population, after Crete, and the sixth largest island in the Mediterranean Sea. It is separated from Boeotia in mainland Greece by the narrow Euripus Strait (only 40 m (130 ft) at its narrowest point). In general outline it is a long and narrow island; it is about 180 km (110 mi) long, and varies in breadth from 50 km (31 mi) to 6 km (3.7 mi). Its geographic orientation is from northwest to southeast, and it is traversed throughout its length by a mountain range, which forms part of the chain that bounds Thessaly on the east, and is continued south of Euboia in the lofty islands of Andros, Tinos and Mykonos.

It forms most of the regional unit of Euboea, which also includes Skyros and a small area of the Greek mainland.

Corinth (/ˈkɒrɪnθ/ KORR-inth; Greek: Κόρινθος, romanized: Kórinthos, Modern Greek pronunciation: [ˈkorinθos]) is a municipality in Corinthia in Greece. The successor to the ancient city of Corinth, it is a former municipality in Corinthia, Peloponnese, which is located in south-central Greece. Since the 2011 local government reform, it has been part of the municipality of Corinth, of which it is the seat and a municipal unit. It is the capital of Corinthia.

It was founded as Nea Korinthos (Νέα Κόρινθος), or New Corinth, in 1858 after an earthquake destroyed the existing settlement of Corinth, which had developed in and around the site of the ancient city.

The Ionian Islands (Modern Greek: Ιόνια νησιά, Ionia nisia; Ancient Greek, Katharevousa: Ἰόνιαι Νῆσοι, Ioniai Nēsoi) are a group of islands in the Ionian Sea, west of mainland Greece. They are traditionally called the Heptanese ("Seven Islands"; Ἑπτάνησα, Heptanēsa or Ἑπτάνησος, Heptanēsos; Italian: Eptaneso), but the group includes many smaller islands in addition to the seven principal ones.

As a distinct historic region, the collective of islands date to the centuries-long Venetian rule, which kept them outside Ottoman control, and created a distinct cultural identity with many Italian influences. The Ionian Islands became part of the modern Greek state in 1864. Administratively today, they belong to the Ionian Islands Region except for Kythera, which belongs to the Attica Region.

Antikythera (/ˌæntɪkɪˈθɪərə/ AN-tik-ih-THEER-ə, US also /ˌæntaɪkɪˈ-/ AN-ty-kih-; Modern Greek: Αντικύθηρα, romanized: Antikýthira, IPA: [andiˈciθira]) or Anticythera, known in antiquity as Aigilia (Αἰγιλία), is a Greek island lying on the edge of the Aegean Sea, between Crete and Peloponnese. Since the 2011 local government reform, it is part of the municipality of Kythira island.

Antikythera may also refer to the Kythira-Antikythira Strait, through which Mediterranean water enters the Sea of Crete.

Olympia (Modern Greek: Ολυμπία [oli(m)ˈbi.a]; Ancient Greek: Ὀλυμπία [olympí.aː]), officially Archaia Olympia (Greek: Αρχαία Ολυμπία lit. 'Ancient Olympia'), is a small town in Elis on the Peloponnese peninsula in Greece, famous for the nearby archaeological site of the same name. The site was a major Panhellenic religious sanctuary of ancient Greece, where the ancient Olympic Games were held every four years throughout classical antiquity, from the 8th century BC to the 4th century AD. They were restored on a global basis in 1894 in honor of the ideal of peaceful international contention for excellence.

The sacred precinct, named the Altis, was primarily dedicated to Zeus, although other gods were worshipped there. The games conducted in his name drew visitors from all over the Greek world as one of a group of such "Panhellenic" centres, which helped to build the identity of the ancient Greeks as a nation. Despite the name, it is nowhere near Mount Olympus in northern Greece, where the twelve Olympians, the major deities of ancient Greek religion, were believed to live.

Koine Greek (ἡ κοινὴ διάλεκτος, hē koinḕ diálektos, lit. 'the common dialect'), also variously known as Hellenistic Greek, common Attic, the Alexandrian dialect, Biblical Greek, Septuagint Greek or New Testament Greek, was the common supra-regional form of Greek spoken and written during the Hellenistic period, the Roman Empire, and the early Byzantine Empire. It evolved from the spread of Greek following the conquests of Alexander the Great in the fourth century BC, and served as the lingua franca of much of the Mediterranean region and the Middle East during the following centuries. It was based mainly on Attic and related Ionic speech forms, with various admixtures brought about through dialect levelling with other varieties.

Koine Greek included styles ranging from conservative literary forms to the spoken vernaculars of the time. As the dominant language of the Byzantine Empire, it developed further into Medieval Greek, which then turned into Modern Greek.

Salamis (/ˈsæləmɪs/ SAL-ə-miss; Ancient Greek and Katharevousa: Σαλαμίς, romanized: Salamís) or Salamina (Modern Greek: Σαλαμίνα, romanized: Salamína) is the largest Greek island in the Saronic Gulf, about two kilometres (one nautical mile) from the coast of Athens' port of Piraeus and about 16 km (8+1⁄2 nmi) west of Athens center.

The chief city, Salamina, lies in the west-facing core of the crescent on Salamis Bay, which opens into the Saronic Gulf. On the eastern side of the island its main port, Paloukia, connects the island with Perama in the western part of Athens urban area through a frequent ferry line and is the second largest port in Greece in terms of passengers, after the port of Piraeus.

Boeotia (/biˈoʊʃ(i)ə/ bee-OH-sh(ee-)ə), sometimes Latinised as Boiotia or Beotia (Greek: Βοιωτία; modern: Viotía; ancient: Boiōtía), is one of the regional units of Greece. It is part of the region of Central Greece. Its capital is Livadeia, and its largest city is Thebes.

Boeotia was also a region of ancient Greece, from before the 6th century BC.

Tiryns (/ˈtɪrɪnz/ or /ˈtaɪrɪnz/; Ancient Greek: Τίρυνς; Modern Greek: Τίρυνθα) is a Mycenaean archaeological site in Argolis in the Peloponnese, and the location from which the mythical hero Heracles was said to have performed his Twelve Labours. It lies 20 km (12 mi) south of Mycenae.

Tiryns was a hill fort with occupation ranging back seven thousand years, from before the beginning of the Bronze Age. It reached its height of importance between 1400 and 1200 BC, when it became one of the most important centers of the Mycenaean world, and in particular in Argolis. Its most notable features were its palace, its Cyclopean tunnels and especially its walls, which gave the city its Homeric epithet of "mighty walled Tiryns". Tiryns became associated with the myths surrounding Heracles, as the city was the residence of the hero during his labors, and some sources cite it as his birthplace.

The kithara (Greek: κιθάρα, romanized: kithára), Latinized as cithara, was an ancient Greek musical instrument in the yoke lutes family. It was a seven-stringed professional version of the lyre, which was regarded as a rustic, or folk instrument, appropriate for teaching music to beginners. As opposed to the simpler lyre, the cithara was primarily used by professional musicians, called kitharodes. In modern Greek, the word kithara has come to mean "guitar"; etymologically, the word guitar derives from kithara.
