Although his early orations were unsuccessful and reveal a lack of real conviction and of coherent strategic and political prioritisation, Demosthenes established himself as an important political personality and broke with Eubulus' faction, of which a prominent member was Aeschines. He thus laid the foundations for his future political successes and for becoming the leader of his own "party" (the issue of whether the modern concept of political parties can be applied in the Athenian democracy is hotly disputed among modern scholars).
