History of Athens in the context of "Pericles with the Corinthian helmet"

Plato (/ˈpleɪtoʊ/ PLAY-toe; Greek: Πλάτων, Plátōn; born c. 428–423 BC, died 348/347 BC) was an ancient Greek philosopher of Classical Athens who is most commonly considered the foundational thinker of the Western philosophical tradition. An innovator of the literary dialogue and dialectic forms, Plato influenced all the major areas of theoretical philosophy and practical philosophy, and was the founder of the Platonic Academy, a philosophical school in Athens where Plato taught the collection of philosophical theories that would later become known as Platonism.

Plato's most famous contribution is his Theory of Forms (or Ideas), which aims to solve what is now known as the problem of universals. He was influenced by the pre-Socratic thinkers Pythagoras, Heraclitus, and Parmenides, although much of what is known about them is derived from Plato himself.

Under the reign of Philip II (359–336 BC), the ancient kingdom of Macedonia, initially at the periphery of classical Greek affairs, came to dominate Ancient Greece in the span of less than 25 years, largely thanks to the character and policies of its king. In addition to utilising effective diplomacy and marriage alliances to achieve his political aims, Philip II was responsible for reforming the ancient Macedonian army into an effective fighting force. The Macedonian phalanx became the hallmark of the Macedonian army during his reign and the subsequent Hellenistic period. His army and engineers also made extensive use of siege engines. Chief among Philip's Thracian enemies was the ruler Kersebleptes, who may have coordinated a temporary alliance with Athens. In a series of campaigns stretching from 356 to 340 BC, Philip II managed to ultimately subjugate Kersebleptes as a tributary vassal, conquering much of Thrace in the process. Philip II also fought against the Illyrian king Bardylis, who threatened Macedonia proper, and against Grabos II and Pleuratus in Illyria (centred in modern-day Albania). In his newly conquered territories, he founded new cities such as Philippi, Philippopolis (modern Plovdiv, Bulgaria), Herakleia Sintike (Pirin Macedonia, Bulgaria), and Herakleia Lynkestis (modern Bitola, North Macedonia).

Philip II eventually campaigned against the city-state of Athens and her allies in the Aegean region, as well as Thebes after the decline of its hegemony in mainland Greece. In the defence of the Amphictyonic League of Delphi and in conjunction with the Thessalian League, Macedonia became a key player in the Third Sacred War (356–346 BC), defeating the Phocians, commanded by Onomarchus, at the Battle of Crocus Field in 352 BC. While poised to launch a direct assault on Athens in 346 BC, the Macedonian king was met with an Athenian embassy that arranged the Peace of Philocrates. As a result, Macedonia and Athens became allies, yet Athens was forced to relinquish its claims to the city of Amphipolis (in modern-day Central Macedonia).

Solon (/ˈsoʊlən/; Ancient Greek: Σόλων; c. 630 – c. 560 BC) was an archaic Athenian statesman, lawmaker, political philosopher, and poet. He was one of the Seven Sages of Greece and is credited with laying the foundations for Athenian democracy. Solon's efforts to legislate against political, economic and moral decline resulted in his constitutional reform overturning most of Draco's laws.

Solon's reforms included debt relief later known and celebrated among Athenians as the seisachtheia (shaking off of burdens). He is described by Aristotle in the Athenian Constitution as "the first people's champion". Demosthenes credited Solon's reforms with starting a golden age.

The second Persian invasion of Greece (480–479 BC) occurred during the Greco-Persian Wars, as King Xerxes I of Persia sought to conquer all of Greece. The invasion was a direct, if delayed, response to the defeat of the first Persian invasion of Greece (492–490 BC) at the Battle of Marathon, which ended Darius I's attempts to subjugate Greece. After Darius's death, his son Xerxes spent several years planning for the second invasion, mustering an enormous army and navy. The Athenians and Spartans led the Greek resistance. About a tenth of the Greek city-states joined the 'Allied' effort; most remained neutral or submitted to Xerxes.

The invasion began in spring 480 BC, when the Persian army crossed the Hellespont and marched through Thrace and Macedon to Thessaly. The Persian advance was blocked at the pass of Thermopylae by a small Allied force under King Leonidas I of Sparta; simultaneously, the Persian fleet was blocked by an Allied fleet at the straits of Artemisium. At the famous Battle of Thermopylae, the Allied army held back the Persian army for three days, before they were outflanked by a mountain path and the Allied rearguard was trapped and annihilated. The Allied fleet had also withstood two days of Persian attacks at the Battle of Artemisium, but when news reached them of the disaster at Thermopylae, they withdrew to Salamis.

The Apollo Lyceus (Greek: Ἀπόλλων Λύκειος, Apollōn Lukeios) type, also known as Lycean Apollo, originating with Praxiteles and known from many full-size statue and figurine copies as well as from 1st century BCE Athenian coinage, is a statue type of Apollo showing the god resting on a support (a tree trunk or tripod), his right forearm touching the top of his head and his hair fixed in braids on the top of a head in a haircut typical of childhood. It is called "Lycean" not after Lycia itself, but after its identification with a lost work described, though not attributed to a sculptor, by Lucian as being on show in the Lyceum, one of the gymnasia of Athens. According to Lucian, the god leaning on a support with his bow in his left hand and his right resting on his head is shown "as if resting after long effort." Its main exemplar is the Apollino in Florence or Apollo Medici, in the Uffizi, Florence.

The attribution, based on the type's "elongated proportions, elegant pose and somewhat effeminate anatomy", as Brunilde Sismondo Ridgway characterised it, is traditionally supported on the grounds of the type's similarity to Praxiteles's Hermes from Olympia – one replica of the Lycian Apollo even passed as a copy of the Hermes for a time. The comparison essentially rests on the Apollino, whose head has proportions similar to those of the Aphrodite of Cnidus and whose pronounced sfumato confirms the long-held idea that it is Praxitelean in style, in spite of the many differences among the extant examples.

The Plague of Athens (Ancient Greek: Λοιμὸς τῶν Ἀθηνῶν, Loimos tôn Athênôn) was an epidemic that devastated the city-state of Athens in ancient Greece during the second year (430 BC) of the Peloponnesian War when an Athenian victory still seemed within reach. The plague killed an estimated 75,000 to 100,000 people, around 25% of the population, and is believed to have entered Athens through Piraeus, the city's port and sole source of food and supplies. Thucydides, an Athenian survivor, wrote that much of the eastern Mediterranean also saw an outbreak of the disease, albeit with less impact.

The war, along with the plague, had lasting effects on Athenian society. Short-term, there was civil disorder, and violations of usual funerary practices. Thucydides describes a decrease in traditional religious practices and increase in superstitious explanations. He estimates that it took 15 years for the Athenian population to recover. Long-term, the high death toll drastically redistributed wealth within Athenian society, and weakened Athens politically.

The Dionysia (/ˌdaɪ.əˈnɪzi.ə, ˌdaɪ.əˈnɪʃi.ə, ˌdaɪ.əˈnɪʃə/; Greek: Διονύσια) was a large festival in ancient Athens in honor of the god Dionysus, the central events of which were processions and sacrifices in honor of Dionysus, the theatrical performances of dramatic tragedies and, from 487 BC, comedies. It was the second-most important festival after the Panathenaia. The Dionysia actually consisted of two related festivals, the Rural Dionysia and the City Dionysia, which took place in different parts of the year.

The Solonian constitution was created by Solon in the early 6th century BC. At the time of Solon, the Athenian State was almost falling to pieces in consequence of dissensions between the parties into which the population was divided. Solon wanted to revise or abolish the older laws of Draco. He promulgated a code of laws embracing the whole of public and private life, the salutary effects of which lasted long after the end of his constitution.

Under Solon's reforms, all debts were abolished and all debt-slaves were freed. The status of the hectemoroi (the "one-sixth workers"), who farmed in an early form of serfdom, was also abolished. These reforms were known as the Seisachtheia. Solon's constitution reduced the power of the old aristocracy by making wealth rather than birth a criterion for holding political positions, a system called timokratia (timocracy). Citizens were also divided based on their land production: pentacosiomedimnoi, hippeis, zeugitae, and thetes. The lower assembly was given the right to hear appeals, and Solon also created the higher assembly. Both of these were meant to decrease the power of the Areopagus, the aristocratic council. Despite the division between classes and citizens, Solon felt these classes were connected as one. Solon felt that a disservice against even just one member of the society would indirectly be a disservice against every member of the society. The only parts of Draconian constitution that Solon kept were the laws regarding homicide. The constitution was written as poetry, and as soon as it was introduced, Solon went into self-imposed exile for ten years so he would not be tempted to take power as a tyrant.

The Battle of Artemisium or Artemision was a series of naval engagements over three days during the second Persian invasion of Greece. The battle took place simultaneously with the land battle at Thermopylae, in August or September 480 BC, off the coast of Euboea and was fought between an alliance of Greek city-states, including Sparta, Athens, Corinth and others, and the Persian Empire of Xerxes I.

The Persian invasion was a delayed response to the defeat of the first Persian invasion of Greece, which had been ended by the Athenian victory at the Battle of Marathon. King Xerxes had amassed a huge army and navy, and set out to conquer all of Greece. The Athenian general Themistocles proposed that the Allied Greeks block the advance of the Persian army at the pass of Thermopylae and simultaneously block the Persian navy at the Straits of Artemisium. An Allied naval force of 271 triremes was thus dispatched to await the arrival of the Persians.

The Battle of Mycale was one of the two major battles (the other being the Battle of Plataea) that ended the second Persian invasion of Greece during the Greco-Persian Wars. It took place on 27 or 28 August, 479 BC on the slopes of Mount Mycale, which is located on the coast of Ionia opposite the island of Samos. The battle was fought between an alliance of Greek city-states, including Sparta, Athens and Corinth; and the Persian Empire of Xerxes I.

The previous year, the Persian invasion force, led by Xerxes himself, had scored victories at the battles of Thermopylae and Artemisium, and conquered Thessaly, Boeotia and Attica; however, at the ensuing Battle of Salamis, the Greek navy had won an unlikely victory, and therefore prevented the conquest of the Peloponnese. Xerxes then retreated, leaving his general Mardonius with a substantial army to finish off the Greeks the following year.

The First Mithridatic War (89–85 BC) was a large conflict in Anatolia and ancient Greece that opposed the Roman Republic and the Pontic kingdom ruled by Mithridates VI Eupator. Although the Roman general Sulla was largely victorious on the battlefield, factional struggle in Rome forced him to end the war on a precarious stalemate.

The war began after more than a decade of geopolitical manoeuvring by Mithridates, who managed to considerably extend his realm despite constant Roman attempts to restrain him. In 90 BC, a Roman delegation headed by Manius Aquillius provoked Mithridates into war, as Aquillius hoped to receive its command. The following year, Mithridates rapidly captured the Roman province of Asia, exploiting local resentment of Roman tax collectors to massacre the Roman settlers. Taken by surprise while it was fighting a large revolt of its allies in Italy, Rome was initially unable to respond. This allowed Mithridates to encourage more defections from Greek cities, most notably Athens, where he installed the tyrant Aristion.

Ammonius Hermiae (/əˈmoʊniəs/; Ancient Greek: Ἀμμώνιος ὁ Ἑρμείου, romanized: Ammōnios ho Hermeiou, lit. 'Ammonius, son of Hermias'; c. 440 – between 517 and 526) was a Greek philosopher from Alexandria in the eastern Roman empire during Late Antiquity. A Neoplatonist, he was the son of the philosophers Hermias and Aedesia, the brother of Heliodorus of Alexandria and the grandson of Syrianus. Ammonius was a pupil of Proclus in Roman Athens, and taught at Alexandria for most of his life, having obtained a public chair in the 470s.

According to Olympiodorus of Thebes's Commentaries on Plato's Gorgias and Phaedo texts, Ammonius gave lectures on the works of Plato, Aristotle, and Porphyry of Tyre, and wrote commentaries on Aristotelian works and three lost commentaries on Platonic texts. He is also the author of a text on the astrolabe published in the Catalogus Codicum Astrologorum Graecorum, and lectured on astronomy and geometry. Ammonius taught numerous Neoplatonists, including Damascius, Olympiodorus of Thebes, John Philoponus, Simplicius of Cilicia, and Asclepius of Tralles. Also among his pupils were the physician Gessius of Petra and the ecclesiastical historian Zacharias Rhetor, who became the bishop of Mytilene.

The Battle of Thermopylae was fought in 279 BC between invading Gallic armies and a combined army of Greek Aetolians, Boeotians, Athenians, and Phocians at Thermopylae. The Gauls under Brennus were victorious, and advanced further into the Greek peninsula where they attempted to sack Delphi but were completely defeated.

The Themistoclean Wall (Greek: Θεμιστόκλειον τείχος), named after the Athenian statesman Themistocles, was built in Athens, Greece during the 5th century BC as a result of the Persian Wars and in the hopes of defending against further invasion.
