She organized anti-Theban oligarchies in the Bœotian cities, with a Spartan harmost.

Lysander established in most of the cities an oligarchy of ten citizens, as well as a Spartan harmost, or governor.

He now destroyed the democratic and popular constitutions in all the Greek cities which had been subject to Athens, placing a Lacedæmonian in each as harmost or governor, with a council of ten archons under him, composed of men selected from the political clubs which he had established.

Lysander now at once subverted the constitution, establishing thirty archons in the city, and ten in Peiræus, placing also a garrison in the Acropolis under the command of Kallibius, who acted as harmost, or governor.
