Thrasydaeus (Ancient Greek : Θρασυδαῖος), tyrant of Agrigentum in Magna Graecia, was the son and successor of Theron. Already during his father's lifetime he had been appointed to the government of Himera, where, by his violent and arbitrary conduct, he alienated the citizens, so that they were close to revolt. But when they sought support from Hiero of Syracuse, he betrayed them to Theron, who then put to death the leaders of the disaffected party and re-established his authority. [1] Whether Thrasydaeus retained his position at Himera after this is unknown; but on the death of Theron (473 BC) he succeeded without opposition to rule both cities. His tyrannical and violent character soon displayed itself, and made him as unpopular at Agrigentum as he had been at Himera. But his first object was to renew the war with Hiero, against whom he had already taken an active part during his father's lifetime. [2] He therefore assembled a large force of mercenaries, besides a general levy from Agrigentum and Himera, and advanced against Hiero, but was defeated after a stubborn and bloody struggle. The Agrigentines immediately took advantage of this disaster to expel him from their city. He made his escape to Greece, but was arrested at Megara, and publicly executed. [3]

Agrigento is a city on the southern coast of Sicily, Italy and capital of the province of Agrigento.
HieronI was the son of Deinomenes, the brother of Gelon and tyrant of Syracuse in Sicily, from 478 to 467 BC. In succeeding Gelon, he conspired against a third brother, Polyzelos.
The Battle of Himera, supposedly fought on the same day as the Battle of Salamis, or at the same time as the Battle of Thermopylae, saw the Greek forces of Gelon, King of Syracuse, and Theron, tyrant of Agrigentum, defeat the Carthaginian force of Hamilcar the Magonid, ending a Carthaginian bid to restore the deposed tyrant of Himera. The alleged coincidence of this battle with the naval battle of Salamis and the resultant derailing of a Punic-Persian conspiracy aimed at destroying the Greek civilization is rejected by modern scholars. Scholars also agree that the battle led to the crippling of Carthage's power in Sicily for many decades. It was one of the most important battles of the Sicilian Wars.
Himera, was a large and important ancient Greek city situated on the north coast of Sicily at the mouth of the river of the same name, between Panormus and Cephaloedium in the comune of Termini Imerese.
The Sicani or Sicanians were one of three ancient peoples of Sicily present at the time of Phoenician and Greek colonization. The Sicani dwelt east of the Elymians and west of the Sicels, having, according to Diodorus Siculus, the boundary with the last in the ancient Himera river (Salso) after a series of battles between these tribes.
The Battle of the Himera River was fought in 311 BC between Carthage and Syracuse near the mouth of the Himera river. Hamilcar, grandson of Hanno the Great, led the Carthaginians, while the Syracusans were led by Agathocles. Agathocles initially surprised the Carthaginians with an attack on their camp, but the Greeks lost the battle when they were attacked by unexpected Carthaginian reinforcements. The Greek army took many casualties as it retreated. Agathocles managed to gather the remains of his army and retreat to Syracuse, but lost control of Sicily.
Ducetius was a Hellenized leader of the Sicels and founder of a united Sicilian state and numerous cities. It is thought he may have been born around the town of Mineo. His story is told through the Greek historian Diodorus Siculus in the 1st century BCE, who drew on the work of Timaeus. He was a native Sicilian, but his education was Greek and was very much influenced by Greek civilization in Sicily. He is sometimes known by the Hellenized name of Douketios.

The Sicilian Wars, or Greco-Punic Wars, were a series of conflicts fought between ancient Carthage and the Greek city-states led by Syracuse over control of Sicily and the western Mediterranean between 580 and 265 BC.
Hicetas was tyrant of Syracuse, Magna Graecia, during the interval between the reign of Agathocles and that of Pyrrhus. After the death of Agathocles his supposed assassin, Maenon, put to death Archagathus, the grandson of Agathocles; and, assuming the command of the army with which the latter was besieging Aetna, directed his arms against Syracuse. Hereupon Hicetas was sent against him by the Syracusans, with a considerable army: but after the war had continued for some time, without any decisive result, Maenon, by calling in the aid of the Carthaginians, obtained the superiority, and the Syracusans were compelled to conclude an ignominious peace. Soon after ensued the revolution which led to the expulsion of the Campanian mercenaries, afterwards known as the Mamertines; and it must have been shortly after this that Hicetas established himself in the supreme power, as Diodorus Siculus relates that he ruled for nine years. The only events of his government that are recorded are a war with Phintias, tyrant of Agrigentum, in which he obtained a considerable victory, and one with the Carthaginians, by whom he was defeated at the river Terias. He was at length expelled from Syracuse by Thynion, an event which took place not long before the arrival of Pyrrhus in Sicily, and must therefore be referred either to 279 BC or 278 BC, either of which dates is consistent enough with the period of nine years allotted to his reign by Diodorus.
Theron, son of Aenesidemus, was a Greek tyrant of the town of Acragas in Sicily in Magna Graecia from 488 BC. According to Polyaenus, he came to power by using public funds allocated for the hire of private contractors meant to assist with a temple building project, to instead hire a personal group of bodyguards. With this force at his disposal, he was able to seize control of the town's government. He soon became an ally of Gelo, who at that time controlled Gela, and from 485 BC, Syracuse. Gelo later became Theron's son-in-law.
The Battle of Selinus, which took place early in 409 BC, is the opening battle of the so-called Second Sicilian War. The ten-day-long siege and battle was fought in Sicily between the Carthaginian forces under Hannibal Mago and the Dorian Greeks of Selinus. The city of Selinus had defeated the Elymian city of Segesta in 415, an event that led to the Athenian invasion of Sicily in 415 and ended in the defeat of Athenian forces in 413. When Selinus again worsted Segesta in 411, Carthage, responding to the appeal of Segesta, had besieged and sacked Selinus after the Carthaginian offer of negotiations had been refused by the Greeks. This was the first step towards Hannibal's campaign to avenge the Carthaginian defeat at the first battle of Himera in 480. The city of Selinus was later rebuilt, but never regained her former status.
Near the site of the first battle and great Carthaginian defeat of 480 BC, the Second Battle of Himera was fought near the city of Himera in Sicily in 409 between the Carthaginian forces under Hannibal Mago and the Ionian Greeks of Himera aided by an army and a fleet from Syracuse. Hannibal, acting under the instructions of the Carthaginian senate, had previously sacked and destroyed the city of Selinus after the Battle of Selinus in 409. Hannibal then destroyed Himera which was never rebuilt. Mass graves associated with this battle were discovered in 2008-2011, corroborating the stories told by ancient historians.
Anaxilas or Anaxilaus, son of Cretines, was a tyrant of Rhegium in Magna Graecia. He was originally from Messenia, a region in the Peloponnese.
Hamilcar I was a Magonid king of Carthage in present-day Tunisia from 510 to 480 BC.
Himilco was a member of the Magonids, a Carthaginian family of hereditary generals, and had command over the Carthaginian forces between 406 BC and 397 BC. He is chiefly known for his war in Sicily against Dionysius I of Syracuse.
The siege of Segesta took place either in the summer of 398 BC or the spring of 397 BC. Dionysius the Elder, tyrant of Syracuse, after securing peace with Carthage in 405 BC, had steadily increased his military power and tightened his grip on Syracuse. He had fortified Syracuse against sieges and had created a large army of mercenaries and a large fleet, in addition to employing catapults and quinqueremes for the first time in history. In 398 BC he attacked and sacked the Phoenician city of Motya despite a Carthaginian relief effort led by Himilco II of Carthage. While Motya was under siege, Dionysius besieged and assaulted Segesta unsuccessfully. Following the sack of Motya, Segesta again came under siege by Greek forces, but the Elymian forces based in Segesta managed to inflict damage on the Greek camp in a daring night assault. When Himilco of Carthage arrived in Sicily with the Carthaginian army in the spring of 397 BC, Dionysius withdrew to Syracuse. The failure of Dionysius to secure a base in western Sicily meant the main events of the Second Sicilian war would be acted out mostly in eastern Sicily, sparing the Elymian and Phoenician cities the ravages of war until 368 BC.
Diocles of Syracuse was a legislator, orator, and political and military leader in the Greek city-state of Syracuse, Magna Graecia, toward the end of the 5th century BC. Only a few years of his life have an historical account, from 413 to 408 BC.
The siege of Syracuse by the Carthaginians from 311 to 309 BC followed shortly after the Battle of the Himera River in the same year. In that battle the Carthaginians, under the leadership of Hamilcar the son of Gisco, had defeated the tyrant of Syracuse, Agathocles. Agathocles had to retreat to Syracuse and lost control over the other Greek cities on Sicily, who went over to the Carthaginian side.
Dandes of Argos was an ancient Greek athlete listed by Eusebius of Caesarea as a victor in the stadion race of the 77th Olympiad. He won two races, but the first was probably in the boys' category, maybe in the 75th Olympiad eight years earlier. He also won once at the Pythian Games and three times at the Nemean Games, according to some sources; elsewhere, his victories were celebrated by Simonides of Ceos in a poem, which claims that he won fifteen times at Nemea – the discrepancy could again be due to victories in boys' races not recorded elsewhere.
The history of Greek Sicily began with the foundation of the first Greek colonies around the mid 8th century BC. The Greeks of Sicily were known as Siceliotes.
