established by Philip on his conquest of that country and overthrow of its
tyrants in B.C. 352, after a defeat in the previous year (Dem.
ii. p. 71.22, τὴν καθεστῶσαν

under the direction of a Spartan harmost. It always consisted of the leading
members of the aristocratical party. (Xen. Hell.
, § 8; Isocr. Panath.
Plut. Lys. 5
and 13; Grote, ch. 72

is used by Demosthenes of the Thessalian

Isocrates of the Lacedaemonian.
