δεομένων γὰρ ξυμμαχίας—in 519 or 509 B.C. (see on c. 68, 5) Plataea, πιεζεύμενοι ὑπὸ Θηβαίων (Herod. VI. 108), applied to king Cleomenes to be admitted to alliance with Sparta.—Note (1) absence of noun with δεομένων, see c. 34, 3 n.: (2) gen. abs. though ἀπεώσασθε follows, a common sacrifice of form to sense in Herod. and Thuc.; for this variety cf. II. 5 ἀναχωρησάντων δὲ πάλιν (sc. αὐτῶν) ἐκ τῆς γῆς ἀποδώσειν αὐτοῖς.
ἀποικούντων—for the case here cf. II. 8 ἐς τοὺς Λακεδαιμονίους, ἄλλως τε καὶ προειπόντων.
ἐν . . τῷ πολέμῳ—viz. ‘this war,’ as often in Thuc.
οὐκ ἠθελήσαμεν—εἰ=ὅτι, hence οὐ.
ὑμῶν κελευσάντων—this occurred in 429 B.C, when the Peloponnesians marched against Plataea. The demand was that Plataea should either join the Lacedaemonian alliance or remain neutral.
εὖ παθών—what services Plataea had received from Athens before she ‘won the alliance’ of 519 (or 509) B.C. is not known.
τις of course, means the Plataeans.
πολιτείας μετέλαβεν—this passage and c. 63 clearly imply that Athenian citizenship in some form was granted to Plataeans settling at Athens since the original alliance; and Isocr. Piat. 51, Pan. 49, Lysias XXIII. 2, and [Dem.] c. Neaer. do not make this assumption impossible. But in II. Thuc. speaks only of a ξυμμαχία between Plataea and Athens, and possibly Thuc. here anticipates. It is certain that citizenship was conferred on the Plataean refugees after the destruction of Plataea. For the ὧν omitted see c. 51, 1 n.
ἃ . . ἐξηγεῖσθε—ἄ is internal accus., and ἐξηγεῖσθε, which is used of the orders issued by the head of a confederacy is imperf.
