1 Introduction
In 1750 BC, a great flood occurred in the  upper reaches of the Cephisus River, north of Mount Parnassus.
The Ectenes, led by Ogygus, migrated  downstream of the Cephisus River and settled southeast of Lake Copais. [1]
In 1580 BC, a group of Ectenes, led by the  grandfather of Hellen's father, Deucalion, migrated from Boeotia to Thessaly  due to oppression by other tribes, including the Hyantes. Deucalion founded  Pyrrha (later Melitaea) at the headwaters of the Enipeus River, which flows  from the south into the Peneius River in northern Thessaly. [2]
Deucalion had two sons, Amphictyon and  Hellen. [3]
Hellen ruled over Phthiotis, and the people  living there were called Hellenes (or Hellas). [4]
      2 Xuthus, son of Hellen
        Hellen had three sons: Aeolus, Xuthus, and  Dorus. [5]
        Hellen's descendants grew in power, with  Aeolus becoming the progenitor of the Aeolians and Dorus becoming the progenitor of  the Dorians.
        Xuthus had two sons: Achaeus and Ion.  Achaeus became the progenitor of the Achaeans and Ion became the progenitor of the Ionians.  [6]
      2.1 Migration of Xuthus
        After Hellen's death in 1470 BC, Aeolus and  Dorus exiled Xuthus from Melitaea. [7]
        Xuthus went to Athens, where his uncle  Amphictyon had once reigned as king, and married Creusa, daughter of  Erichthonius, the fourth king of Athens. Xuthus founded Tetrapolis (Oenoe,  Marathon, Probalinthus, and Tricorynthus) in northeastern Attica, drawing on a  population from the surrounding areas.[8]
        In 1442 BC, Xuthus moved to Aegialus (later  part of Achaia), northeastern of the Peloponnesus.[9]
      2.2 Xuthus's Settlement
        Aegialus is the name of a region, and the  exact location of Xuthus's settlement is unknown.
        When Xuthus migrated from Attica to  Aegialus, Aegialeia and Hyperesia (later Aegeira) existed northeast of the  Peloponnesus.
        Aegialeia was founded in 1750 BC by  Aegialeus (or Aezeius), son of Inachus. [10]
        Hyperesia was founded in 1450 BC by  Hyperetus, son of Lycaon. [11]
        Xuthus's settlement is believed to have  been between Aegialeia and Hyperesia. [12]
        About 160 years after Xuthus's settlement,  a town named after Gonussa, the daughter of Erechtheus, the sixth king of  Athens, was founded there. [13]
        During the time of Gonussa, the descendants  of those who migrated from Attica with Xuthus likely lived in the area.
      3 Progenitor, Ion
        Ion was the son of Xuthus, son of Hellen,  and Creusa, daughter of Erichthonius, the fourth king of Athens. [14]
        In 1442 BC, Ion migrated with his father  Xuthus from Attica to Aegialus, north of the Peloponnesus. [15]
        In 1440 BC, Ion married Helice, daughter of  Selinus, king of the Aegialians. [16]
        Selinus is presumed to be the son of  Hyperetus, the founder of Hyperesia.
        Ion succeeded Selinus as king of Hyperesia  and became king of the Aegialians. [17]
        In 1430 BC, Ion founded Helice, located  northwest of Hyperesia. [18]
        The people living in the region under Ion's  rule came to be called Ionians. [19]
      3.1 Achaeus, Brother of Ion
        In 1435 BC, Ion's brother Achaeus emigrated  to Melitaea in Thessaly, where his father, Xuthus, had been exiled. [20]
        In 1420 BC, Achaeus returned to Aegialus  from Thessaly. [21]
        In 1408 BC, Achaeus's two sons, Archander  and Architeles, married the daughters of Danaus from Argos and subsequently  emigrated to Argos. [22]
      3.2 Battle with Eumolpus
        In 1415 BC, a large group led by Eumolpus  invaded Attica. [23]
        The Athenians took refuge near Tanagra in  eastern Boeotia, where the Gephyraeans (a branch of the Phoenicians) who had  migrated with Cadmus inhabited. [24]
        Pandion, the fifth king of Athens, sought  the help of Ion, the son of his sister Creusa. Ion was nominated by the  Athenians as Polemarch, fought against Eumolpus, and negotiated a truce. [25]
      3.3 Migration to Attica
        Ion lived in Potami, eastern Attica, and  was involved in Athenian politics. He divided the population into four tribes  and named them after his four sons. He divided the Athenians into four groups  based on their occupations: farmers, artisans, priests, and guards. [26]
        Ion died in Attica and was buried in  Potami. [27]
      4 Ionians of Achaia
        4.1 Ion's Children
        Ion had four sons: Geleon, Aegicores,  Argades, and Hoples. [28]
        The Athenians were divided into four tribes  named after Ion's four sons, and the tribal names were used for 900 years until  they were changed in the 6th century BC. [29]
        Ion also had a daughter, Bura, whose name  was given to her, a town named after her, located a little east of Helice. [30]
      4.2 Descendants of Ion remaining in  Aegialus
        In addition to his four sons who lived in  Attica, Ion had other sons who likely inherited the territory of Aegialus.
        Their territories likely included the  following areas:
        1) The land west of Sicyon, where Xuthus  settled and his son Achaeus inherited it.
        2) Hyperesia, which Ion inherited from  Selinus.
        3) Helice, founded by Ion.
      4.3 Migration to Lesbos
        In 1389 BC, the Ionians of Aegialus  emigrated to Pelasgia (later Lesbos) in a colony led by Macareus, son of  Aeolus, son of Hippotes, of Olenus. Macareus's colony included not only Ionians  but also Aeolis and Pelasgians. [31]
      4.4 Migration to Athens
        In 1104 BC, Tisamenus, son of Orestes, who  had surrendered Sparta to the Heracleidae, led the Achaeans to the northern  Peloponnesus. Tisamenus offered to live with the indigenous Ionians, but they  refused, leading to war. The Ionians were cornered by the Achaeans and besieged  at Helice. [32]
        In 1102 BC, the Ionians signed a truce with  the Achaeans and fled to Athens. Melanthus, king of Athens, welcomed the  Ionians. Melanthus accepted the Ionians not out of kindness to his people, but  as a military force against the Dorians. [33]
      5 Ionians of Attica and Megara
        5.1 Migration from Attica to Aegina
        During the invasion of Eumolpus in 1415 BC,  the inhabitants of Oenoe, a Tetrapolis in northeastern Attica, migrated to an  island in the Saronic Gulf near Epidaurus. [34]
        The island came to be called Oenoe (later  Aegina). [35]
        The inhabitants of Oenoe in Attica were  migrants from Thessaly, led by Xuthus, son of Hellen. [36]
      5.1.1 Migration from Aegina to Epidaurus
        In 1287 BC, Aeacus, son of Actor, migrated  from Dia in Thessaly to Oenoe, and the island came to be called Aegina. [37]
        The Ionians, originally from Aegina,  migrated to Epidaurus under the leadership of the descendants of Ion, son of  Xuthus. [38]
      5.2 Migration from Attica to Epidaurus
        Ionians from Tetrapolis in Attica also  participated in the Heracleidae expedition.
        In 1102 BC, Deiphontes, son of Antimachus,  led Dorians from Argos and occupied Epidaurus. [39]
        Deiphontes settled the Ionians, who had  participated in the expedition from Tetrapolis, to Epidaurus. [40]
      5.2.1 Migration from Epidaurus to Athens
        In 1102 BC, the Ionians who had lived in  Epidaurus, which Deiphontes had occupied, migrated to Athens under the  leadership of Pityreus, a descendant of Ion, son of Xuthus. [41]
        In 1095 BC, Procles, son of Pityreus, led  the Ionians who had migrated from Epidaurus to Athens to settle in Samos. [42]
      5.3 Migration from Attica to Euboea
        Attica, which had become overpopulated  after accepting the Ionians whose lands had been seized by the Dorians, sent a  migration to Euboea.
        In 1085 BC, Xuthus' three sons, Cothus,  Aeclus, and Ellops, founded Chalcis, Eretria, and Ellopia in Euboea,  respectively. Ellops also captured the surrounding areas, including Histiaea.  [43]
        The Ionians changed their name to  Chalcidians and Eretrians.
      5.3.1 Migration from Euboea to Chios
        In 1075 BC, Amphiculus, likely the brother  of Xuthus' son Ellops, led a migration from Histiaea to Chios. [44]
        Xuthus was ethnically Phoenician, his  ancestors being Gephyraeans who had migrated to Boeotia with Cadmus and settled  around Tanagra.
        Pausanias writes that he does not  understand why Hector, a descendant of Amphiculus, was able to join the Ionian  League. Hector was able to do so because they were the Ionians who had migrated  to Chios with Amphiculus. [45]
      5.4 Migration from Megara to Attica
        In 1074 BC, the Dorians, alarmed by the  growing population of Athens, invaded the city. [46]
        The Dorians failed in their attempt to  capture Athens, but on their way back, they expelled the Ionians from Megara,  which was then part of Athens' territory, and founded the city. [47]
        The Ionians, driven from Megara, settled in  Brauron on the east coast of Attica.
        Philaeus, son of Ajax, had previously  emigrated from Megara to Brauron. [48]
      6 Colonization to Asia Minor
        In 1073 BC, Neileus, son of Codrus, led a  group of immigrants from Athens to Miletus in Asia Minor. [49]
        Colonization of Asia Minor continued for  the next 30 years, with many towns being founded.
        These towns were not only inhabited by  Ionians, but also by Abantes, Minyans, and Cadmeians. [50]
        Also included were the Dryopians, the  Phocians (excluding the Delphians), the Molossians, the Arcadians, and the  Dorians, newcomers to Epidaurus. [51]
        The region of their towns was called Ionia,  and they held a common festival at Panionium near Priene. [52]
      7 Spread of  Ionian Settlements
        In 1430 BC, the Ionians were born in  Helice, north of the Peloponnesus.
        In 1415 BC, the Ionians who  lived in Helice, led by Ion, migrated to Attica.
        In 1389 BC, the Ionians who  lived in the north of the Peloponnesus migrated to Lesbos.
        In 1102 BC, the Ionians who  lived in the north of the Peloponnesus, driven by the Achaeans,  migrated to Athens.
        In 1102 BC, the Ionians who  lived in Epidaurus in Argolis, driven by the Dorians, migrated to  Athens.
        In 1102 BC, the Ionians who  lived in Attica migrated to Epidaurus.
        In 1095 BC, the Ionians who  lived in Athens migrated to Samos.
        In 1085 BC, the Ionians who  lived in Athens migrated to Euboea.
        In 1075 BC, the Ionians who  lived in Euboea migrated to Chios.
        In 1074 BC, the Ionians who  lived in Megara migrated to Attica.
        Between 1073 and 1043 BC, Ionians migrated  from Athens to Ionia in Asia Minor.
      8 Greek Dark Ages
        The majority of Ionians lived in Ionia in  Asia Minor.
        Ionians also lived in Attica, Epidaurus,  and Euboea.
