In the revived democracy established in 403 BC, Thrasybulus became a major and prestigious leader, although he was soon superseded at the head of the state by Archinus.
Thrasybulus largely faded from view for several years as Conon led the Athenian fleet to a series of victories, but in 392 BC Conon was imprisoned by the Persian satrap Tiribazus while attending a peace conference at Sardis; although released, he died in Cyprus without returning to Athens.
