154 HISTORY OF GREECE. reads the sad narrative of the Korkyrsean sedition, in the third book of Thucydides, together with the reflections of the historian upon it, 1 will trace the gradual exasperation of these party feuds, beginning even under democratical forms, until at length they break down the barriers of public as well as of private morality. Against this chance of internal assailants Kleisthenes had to protect the democratical constitution, first, by throwing impedi- ments in their way and rendering it difficult for them to procure the requisite support ; next, by eliminating them before any vio- lent projects were ripe for execution.
