Amphipolis was planted by a colony of Athenians and other Greeks, under the conduct of the Athenian Agnon, in 437 B.C. It was situated near the river Strymon, in Thrace, on the eastern bank, and at the spot where the Strymon resumes its river-course after emerging from the lake above. It was originally a township or settlement of the Edonian Thracians, called Ennea Hodoi, or Nine Ways,—in a situation doubly valuable, both as being close upon the bridge over the Strymon, and as a convenient centre for the ship-timber and gold and silver mines of the neighboring region,—and distant about three English miles from the Athenian settlement of Eion at the mouth of the river. The previous unsuccessful attempts to form establishments at Ennea Hodoi have already been noticed,—first, that of Histiæus the Milesian, followed up by his brother Aristagoras (about 497-496 B.C.), next, that of the Athenians about 465 B.C., under Leagrus and others,—on both these occasions the intruding settlers had been defeated and expelled by the native Thracian tribes, though on the second occasion the number sent by Athens was not less than ten thousand.[20] So serious a loss deterred the Athenians for a long time from any repetition of the attempt: though it is highly probable that individual citizens from Eion and from Thasus connected themselves with powerful Thracian families, and became in this manner actively engaged in mining, to their own great profit,—as well as to the profit of the city collectively, since the property of the kleruchs, or Athenian citizens occupying colonial lands, bore its share in case of direct taxes being imposed on Athenian property generally. Among such fortunate adventurers we may number the historian Thucydidês himself; seemingly descended from Athenian parents intermarrying with Thracians, and himself married to a wife either Thracian or belonging to a family of Athenian colonists in that region, through whom he became possessed of a large property in the mines, as well as of great influence in the districts around.[21] This was one of the various ways in which the collective power of Athens enabled her chief citizens to enrich themselves individually.

See Rotscher, Leben des Thukydides, ch. i, 4, p. 96, who gives a genealogy of Thucydidês, as far as it can be made out with any probability. The historian was connected by blood with Miltiadês and Kimon, as well as with Olorus, king of one of the Thracian tribes, whose daughter Hegesipylê was wife of Miltiadês, the conqueror of Marathon. In this manner, therefore, he belonged to one of the ancient heroic families of Athens, and even of Greece, being an Ækid through Ajax and Philæus (Marcellin. c. 2).
