The Achaeans constitute one of the collective names for the Greeks in Homer's Iliad and Odyssey. The other common names are Danaans and Argives while Panhellenes and Hellenes both appear only once; all of the aforementioned terms were used synonymously to denote a common Greek civilizational identity. In the historical period, the Achaeans were the inhabitants of the region of Achaea, a region in the north-central part of the Peloponnese. The city-states of this region later formed a confederation known as the Achaean League, which was influential during the 3rd and 2nd centuries BC.
