It is supposed that they were partly induced to make this declaration by finding the sons of Codrus evince an inclination to involve the country in a civil war regarding the succession to the throne. The Athenians therefore abolished royalty altogether, and appointed Medon, Codrus’s eldest son, under the title of _Archon_, as chief magistrate of the republic for life; the office to be hereditary in his family as long as its duties should be performed to the satisfaction of the people. And as Attica was overcrowded with the Peloponnesian refugees, these, together with a large body of Athenians, were sent into Asia Minor, under the charge of Androclus and Neleus, the younger sons of Codrus, to plant colonies to the south of those already formed in Æolia. The settlers founded twelve cities, some of which afterwards rose to great wealth and splendor. _Ionia_ was the name bestowed upon the district, in reference to the Ionic stock from which the Athenians drew their descent.
Several Dorian colonies in Caria, a province still farther south than Ionia, completed the range of Grecian settlements along the western coast of Asia Minor. Cyprus, Rhodes, the coast of Thrace, and the islands of the Ægean Sea, together with a considerable portion of Italy and Sicily, and even of France and Spain, were also colonized by bands of adventurers, who at various periods emigrated from Greece; so that, in process of time, the Grecian race, language, religion, institutions, and manners, instead of being confined to the comparatively small country constituting Greece proper, were diffused over a very extensive region, comprising the fairest portions of Europe and of western Asia.
While this work of colonization was going forward, the parent states of Greece were torn with internal dissensions, and were perpetually harassing each other in wars, of which the objects and incidents are now equally uncertain. Almost all that is known of the history of the two centuries immediately following the death of Codrus is, that they were characterized by great turbulence and confusion, and that, during their lapse, many of the Grecian states and colonies followed the example of Athens by abolishing monarchy. Others did not, till a later period, become republican, and Sparta long retained the singular form of regal government established there at the accession of the twin brothers Eurysthenes and Procles, the descendants of whom continued for several centuries to reign jointly in Lacedæmon, though, practically speaking, no state of Greece was more thoroughly republican in many important respects.
