==Leader of the Delian League==

The excuse that the threat of Persia gave and Athens' wealth proved to be key in Athens consolidating power within the Delian league (Figure 1). This led to strife within the league, as the Greek cities began to revolt against Athens increased consolidation of power. Under the Athenian Pericles, the Athenians moved the treasury of the league to Athens. The city also continued to consolidate and take monetary resources, increasing its wealth and power. The cities and regions that followed Athens essentially formed an empire under Athens' leadership by the 450s. In fact, in 460 BCE, tensions were high and the Peloponnesian Wars began as rebellions of Greek cities against Athenian hegemony. The Athenians were initially successful in taking control much of the Peloponnese peninsula. However, costly wars against the Persians eventually led Athens to make peace with Persia, although they had lost many men and spent much of their wealth in being defeated in Egypt.
