History
The Peloponnese was the heart of Bronze Age Greece. Between about 1600 and 1200 BC the palaces of Mycenae, Tiryns and Pylos ruled the plains around them, and the clay tablets found at Pylos preserve some of the earliest written Greek. In the classical centuries Sparta held the peninsula through its league of allies and its Messenian helots, Corinth grew rich on the portage across the Isthmus, and every four years from, by tradition, 776 BC the Greek world met at Olympia. Thebes ended Spartan power in 371 BC and freed Messenia; Rome razed Corinth in 146 BC, and after winning the sea battle of Actium off the Acarnanian coast in 31 BC Octavian refounded Patras as a Roman colony.
After the Fourth Crusade of 1204 French knights made the peninsula the Principality of Achaea, governed from Andravida and guarded by castles such as Chlemoutsi. The Byzantines returned in 1262, and their Despotate of the Morea, ruled from Mystras above Sparta, became the last centre of Byzantine art and learning. The Ottomans took the Morea in 1460, while Venice clung to Methoni, Koroni, Nafplio and Monemvasia and came back to rule the whole peninsula from 1687 to 1715. The Holy League destroyed the Ottoman fleet off Lepanto, today's Nafpaktos, in 1571.
The revolution of 1821 began here. The Maniots rose at Areopoli on 17 March, Kalamata fell six days later, and Kolokotronis took Tripoli later that year. Byron died at Messolonghi in April 1824, and the town's starving defenders broke out through the Ottoman lines in April 1826; an allied fleet sank the Ottoman-Egyptian navy in Navarino Bay in October 1827, and Nafplio was the capital of the new state until the court moved to Athens in 1834. German troops shot the men of Kalavryta on 13 December 1943, and the Rio–Antirrio bridge joined the two halves of the region in 2004.
