Themistocles, with his power-base firmly established among the poor, moved naturally to fill the vacuum left by Miltiades's death, and in that decade became the most influential politician in Athens. However, the support of the nobility began to coalesce around the man who would become Themistocles's great rival—Aristides. Aristides cast himself as Themistocles's opposite—virtuous, honest and incorruptible—and his followers called him "the just". Plutarch suggests that the rivalry between the two had begun when they competed over the love of a boy: "... they were rivals for the affection of the beautiful Stesilaus of Ceos, and were passionate beyond all moderation."
