Certainly influenced by Alexander the Great, Mithridates VI extended his propaganda from "defender" of Greece to the "great liberator" of the Greek world as war with the Roman Republic became inevitable. The Romans were easily translated into "barbarians", in the same sense as the Persian Empire during the war with Persia in the first half of the 5th century BC and during Alexander's campaign. How many Greeks genuinely bought into this claim will never be known. It served its purpose; at least partially because of it, Mithridates VI was able to fight the First War with Rome on Greek soil, and maintain the allegiance of Greece. His campaign for the allegiance of the Greeks was aided in no small part by his enemy Sulla, who allowed his troops to sack the city of Delphi and plunder many of the city's most famous treasures to help finance his military expenses.
