(pĕl'əpənē`səs) or


(pâ'lôpô`nyēsôs), formerly


(mōrē`ə), peninsula (1991 pop. 1,086,935), c.8,300 sq mi (21,500 sq km), S Greece. It is linked with central Greece by the Isthmus of Corinth, and it is washed by the Aegean Sea on the east and southeast, by the Ionian Sea on the southwest and west, and by the gulfs of Pátrai and Corinth on the north. Its deeply indented south coast terminates in Cape Matapan. Mainly mountainous, the region includes the Taygetus, Kyllene, and Erímanthos mts. The Evrótas and Alfiós are the chief rivers. Near Pátrai in the north, the Charilaos Trikoupis, or Rio–Antirrio, Bridge (2004) connects the peninusula with mainland Greece.


Predominately agricultural and pastoral, the Peloponnesus produces currants, grapes, figs, citrus fruit, olives, tobacco, and wheat. The most fertile parts of the peninsula are the coastal strips in the north and west. Sheep and goat raising, textile manufacturing, fishing, and sericulture are major sources of income. There are deposits of pyrite, manganese, lignite, and chromium. The peninsula attracts many tourists; the port cities of Pátrai, Corinth, Kalamata, and Návplion are the main modern centers of the Peloponnesus.

), the French Villehardouin family received the principality of Achaia or Achaea (i.e., the Peloponnesus) as fief, except for several ports, which passed to Venice. A French feudal state was created and enjoyed a period of great prosperity and chivalrous culture under the Villehardouin princes. Many castles remain to show the unique mixture of French feudal culture and Hellenistic civilization that flourished in the Peloponnesus in the 13th cent. After the death (1278) of William of Villehardouin, the last prince, the principality passed first to the Angevin dynasty of Naples (by marriage), later to various nobles, and in 1383 to a body of Navarrese soldier-adventurers.

The Byzantine Greeks meanwhile had gradually recovered a good part of the peninsula, and in 1432 they achieved complete control. Their triumph, however, was short-lived, for by 1460 Sultan Muhammad II had conquered the peninsula and annexed it to the Ottoman Empire. In the Turko-Venetian Wars from the 15th cent. until the Treaty of Passarowitz (1718), Venice held parts of the Peloponnesus at various times and the entire peninsula from 1687 to 1715. As a result of the Greek War of Independence (1821–29) the peninsula passed to independent Greece.



a peninsula in Greece, the southern part of the Balkan peninsula. It is connected with the mainland by the Isthmus of Corinth, which is cut by the Corinth Canal. Area, 21,500 sq km.

The Peloponnesus is washed by the waters of the Ionian and Aegean seas and their gulfs. Its shoreline is deeply indented, with many gulfs, bays, and peninsulas. Mountains predominate, composed primarily of Mesozoic and Paleogenic limestones, marbles, sandstones, conglomerates, and marls and schists. The chief mountain ranges, which have rocky limestone crests, are the Taiyetos, with elevations to 2,404 m (at Mount Ayios Ilias), and Parnon. In the central part is the Arcadian karst plateau, with karren, conical depressions, and poljes.

The Peloponnesus has a subtropical Mediterranean climate. Annual precipitation ranges from 400 mm in the east to 1,000 mm in the west; in summer there is drought. The peninsula’s vegetation is primarily scrub and evergreen (maquis) in the west and evergreen deciduous (xerophytic) in the east. On the western windward slopes are remnants of oak, fir, and pine forests. Much of the area is rocky wasteland. Olives, citrus and other fruits, tobacco, wheat, and corn are cultivated in the basins and valleys, and there are orchards. Livestock is raised, primarily sheep and goats. The cities of Sparta, Corinth, and Patras are located on the Peloponnesus, as are the ruins of Mycenae and Olympia.
