The Peloponnese, Peloponnesos or Peloponnesus (Greek: Πελοπόννησος, Pelopónnisos; see also list of Greek place names), is a large peninsula, located in a region of southernGreece, forming the part of the country south of the Gulf of Corinth. During the late Middle Agesand the Ottoman era, the peninsula was known as the Morea (Greek: Μωρέας, colloq. Μωριάς), a name still in colloquial use.
The peninsula is divided among three regions of Greece: most of it belongs to the Peloponneseregion, and parts belong to the West Greece and Attica regions.
It was here that the Greek War of Independence began; the Peloponnesians have had an almost total dominance of politics and government in Greece since then.
