Ancient Greece

The first Persian invasion of Greece took place from 492 BC to 490 BC, as part of the Greco-Persian Wars. It ended with a decisive Athenian-led victory over the Achaemenid Empire during the Battle of Marathon. Consisting of two distinct campaigns, the invasion of the independent Greek city-states was ordered by the Persian king Darius the Great, who sought to punish Athens and Eretria after they had supported the earlier Ionian Revolt. Additionally, Darius also saw the subjugation of Greece as an opportunity to expand into Southeast Europe and thereby ensure the security of the Achaemenid Empire's western frontier.

The first campaign, in 492 BC, was led by the Persian commander Mardonius, who re-subjugated Thrace and forced Macedon to become a fully subordinate client kingdom within the Achaemenid Empire; it had been a Persian vassal as early as the late 6th century BC—probably in 512 BC. However, further progress was prevented when Mardonius' fleet was wrecked in a storm off the coast of Mount Athos. The following year, having demonstrated his intentions, Darius sent envoys to all parts of Greece, demanding their submission. He received it from almost all of them, but not from Athens and Sparta, both of which executed the envoys sent to them. With Athens still defiant, and Sparta now effectively at war with the Persians, Darius ordered a further military campaign for the following year.

Leonidas I (/liəˈnaɪdəs, -dæs/; Ancient Greek: Λεωνίδας, Leōnídas; born c. 540 BC; died 11 August 480 BC) was king of the Ancient Greek city-state of Sparta. He was the son of king Anaxandridas II and the 17th king of the Agiad dynasty, a Spartan royal house which claimed descent from Heracles. Leonidas I ascended to the throne in c. 489 BC, succeeding his half-brother king Cleomenes I. He ruled jointly along with king Leotychidas II until his death in 480 BC, when he was succeeded by his son, Pleistarchus.

At the Second Greco-Persian War, Leonidas led the allied Greek forces in a last stand at the Battle of Thermopylae (480 BC), attempting to defend the pass from the invading Persian army, and was killed early during the third and last day of the battle. Leonidas entered myth as a hero and the leader of the 300 Spartans who died in battle at Thermopylae. While the Greeks lost this battle, they were able to expel the Persian invaders in the following year.

The Achaemenid Empire (/əˈkiːmənɪd/ ə-KEE-mə-nid; Old Persian: 𐎧𐏁𐏂, Xšāça, lit. 'The Empire' or 'The Kingdom') was an ancient Iranian empire founded by Cyrus the Great of the Achaemenid dynasty in 550 BC. At peak, its territorial extent was roughly 5.5 million square kilometres (2.1 million square miles), making it the largest empire of its time. Based in the Iranian plateau, it stretched from the Balkans and Egypt in the west to the Indus Valley in the east, including Anatolia, Cyprus, Mesopotamia, the Levant, parts of Eastern Arabia, and large parts of Central Asia.

By the 7th century BC, the region of Persis, located in the southwestern part of the Iranian plateau, had been settled by Persians. From Persis, Cyrus rose and defeated Media, Lydia, and the Neo-Babylonian Empire, thus marking the establishment of a new imperial polity in the ancient Near East. While its conquests were largely successful in most regions, the Achaemenid Empire's attempts to expand into Greece proved extremely difficult over the course of decades of wars and multiple kings, ultimately resulting in its defeat in the Greek mainland.

Elis (Ancient Greek: Ἦλις, Doric Greek: Ἆλις, in the local dialect: Ϝᾶλις, Modern Greek: Ήλιδα, romanized: Elida) was the capital city of the ancient polis (city-state) of Elis, in ancient Greece. It was situated in the northwest of the Peloponnese, to the west of Arcadia. Just before the Peneius emerges from the hills into the plain, the valley of the river is contracted on the south by a projecting hill of a peaked form, and nearly 500 feet (150 m) in height. This hill was the acropolis of Elis, and commanded as well the narrow valley of the Peneius as the open plain beyond. The ancient city lay at the foot of the hill, and extended across the river, as Strabo says that the Peneius flowed through the city; but since no remains are now found on the right or northern bank, it is probable that all the public buildings were on the left bank of the river, more especially as Pausanias does not make any allusion to the river in his description of the city.

Elis is mentioned as a town of the Epeii by Homer in the Catalogue of Ships in the Iliad; but in the earliest times the two chief towns in the country appear to have been Ephyra the residence of Augeias, in the interior, and Buprasium on the coast. Some writers suppose that Ephyra was the more ancient name of Elis, but it appears to have been a different place, situated upon the Ladon. Elis first became a place of importance upon the invasion of Peloponnesus by the Dorians. Oxylus and his Aetolian followers appear to have settled on the height which later formed Elis's acropolis as the spot best adapted for ruling the country. From this time it was the residence of the kings, and of the aristocratic families who governed the country after the abolition of royalty. Elis was the only fortified town in the country; the rest of the inhabitants dwelt in unwalled villages, paying obedience to the ruling class at Elis.

Athens is the capital and largest city of Greece. A significant coastal urban area in the Mediterranean, Athens is also the capital of the Attica region and is the southernmost capital on the European mainland. With its urban area's population numbering over 3.6 million, it is the eighth-largest urban area in the European Union (EU). The Municipality of Athens (also City of Athens), which constitutes a small administrative unit of the entire urban area, had a population of 643,452 in 2021, within its official limits, and a land area of 38.96 km (15.04 sq mi).

Athens is one of the world's oldest cities, with its recorded history spanning over 3,400 years, and its earliest human presence beginning somewhere between the 11th and 7th millennia BCE. According to Greek mythology the city was named after Athena, the ancient Greek goddess of wisdom, but modern scholars generally agree that the goddess took her name after the city. Classical Athens was one of the most powerful city-states in ancient Greece. It was a centre for democracy, the arts, education and philosophy, and was highly influential throughout the European continent, particularly in Ancient Rome. For this reason it is often regarded as the cradle of Western civilisation and the birthplace of democracy in its own right independently from the rest of Greece.

The history of Sparta describes the history of the ancient Doric Greek city-state known as Sparta from its beginning in the legendary period to its incorporation into the Achaean League under the late Roman Republic, as Allied State, in 146 BC, a period of roughly 1000 years. Since the Dorians were not the first to settle the valley of the Eurotas River in the Peloponnesus of Greece, the preceding Mycenaean and Stone Age periods are described as well. Sparta went on to become a district of modern Greece. Brief mention is made of events in the post-classical periods.

Dorian Sparta rose to dominance in the 6th century BC. At the time of the Persian Wars, it was the recognized leader by assent of the Greek city-states. It subsequently lost that assent through suspicion that the Athenians were plotting to break up the Spartan state after an earthquake destroyed Sparta in 464 BC. When Sparta defeated Athens in the Peloponnesian War, it secured an unrivaled hegemony over southern Greece. Sparta's supremacy was broken following the Battle of Leuctra in 371 BC. It was never able to regain its military superiority and was finally absorbed by the Achaean League in the 2nd century BC.

Thespiae (/ˈθɛspi.iː/ THESP-ee-ee; Ancient Greek: Θεσπιαί, romanized: Thespiaí) was an ancient Greek city (polis) in Boeotia. It sits at the foot of Mount Helicon and near right bank of the Thespius River (modern name Kanavari River).

Thespiae was a Boeotian state sporadically involved in the military federal league known as the Boeotian League. The Boeotian League began in 520 BCE under the leadership of Thebes.

Neleides or Nelides (/ˈniːliɪdz/ NEEL-ee-idz; Ancient Greek: Nηλείδης; also Neleiades, Νηληιάδης, and Neleius), in the plural Neleidae (Ancient Greek: Νηλεῖδαι), was a patronymic of ancient Greece derived from Neleus, son of the Greek god Poseidon, and was used to refer to his descendants. In literature, this name typically designated either Nestor, the son of Neleus, or Antilochus, his grandson. One notable offshoot of this family line was the Alcmaeonidae.

In ancient Greece the chief magistrate in various Greek city states was called eponymous archon (ἐπώνυμος ἄρχων, epōnymos archōn). "Archon" (ἄρχων, pl. ἄρχοντες, archontes) means "ruler" or "lord", frequently used as the title of a specific public office, while "eponymous" means that he gave his name to the year in which he held office, much like the Roman dating by consular years.

In Classical Athens, a system of nine concurrent archons evolved, led by three respective remits over the civic, military, and religious affairs of the state: the three office holders were known as the eponymous archon (ruler of Athens, the highest political office in the city-state), the polemarch (πολέμαρχος, "war ruler", the commander-in-chief of the Athenian military), and the archon basileus (ἄρχων βασιλεύς, "king ruler", the high priest of the city). The six others were the thesmothetai, judicial officers. Originally these offices were filled from the wealthier classes by elections every ten years. During this period the eponymous archon was the chief magistrate, the polemarch was the head of the armed forces, and the archon basileus was responsible for some civic religious arrangements, and for the supervision of some major trials in the law courts. After 683 BC the offices were held for only a single year, and the year was named after the eponymous archon.

Sicyon (/ˈsɪʃiˌɒn, ˈsɪs-/; Greek: Σικυών; gen.: Σικυῶνος) or Sikyōn was an ancient Greek city state situated in the northern Peloponnesus between Corinth and Achaea on the territory of the present-day regional unit of Corinthia. The ruins lie just west of the modern village of Sikyona (previously Vasiliko). An ancient monarchy at the times of the Trojan War, the city was ruled by a number of tyrants during the Archaic and Classical period and became a democracy in the 3rd century BC. Sicyon was celebrated for its contributions to ancient Greek art, producing many famous painters and sculptors. In Hellenistic times it was also the home of Aratus of Sicyon, the leader of the Achaean League.
