Monemvasia is a town and a municipality in Laconia, Greece. The town is located on a small island off the east coast of the Peloponnese. The island is linked to the mainland by a short causeway 200m in length. Its area consists mostly of a large plateau some 100 metres above sea level, up to 300 m wide and 1 km long, the site of a powerful medieval fortress. The town walls and many Byzantine churches remain from the medieval period. The seat of the municipality is the town Molaoi.

The town's name derives from two Greek words, mone and emvasia, meaning "single entrance". Its Italian form, Malvasia, gave its name to Malmsey wine. Monemvasia's nickname is the Gibraltar of the East or The Rock.he town and fortress were founded in 583 by inhabitants of the mainland seeking refuge from the Slavic and the Avaric invasion of Greece. A history of the invasion and occupation of the Peloponnese was recorded in the medieval Chronicle of Monemvasia. From the 10th century AD, the town developed into an important trade and maritime centre. The fortress withstood the Arab and Norman invasions in 1147; farm fields that fed up to 30 men were tilled inside the fortress. William II of Villehardouin took it in 1248, on honourable terms, after three years of siege; in 1259 William was captured by the Greeks after the battle of Pelagonia and in 1262 it was retroceded to Michael VIII Palaiologos as part of William's ransom.

It remained part of the Byzantine Empire until 1460, becoming the seat of an imperial governor, a landing place for Byzantine operations against the Franks, the main port of shipment (if not always production) for Malmsey wine, and one of the most dangerous lairs of corsairs in the Levant. The Emperors gave it valuable privileges, attracting Roger de Lluria who sacked the lower town in 1292. The town welcomed the Catalan Company on its way eastward in 1302. In 1397 the Despot of the Morea, Theodore I Palaiologos, deposed the local dynast of Monemvasia, who appealed to Sultan Bayezid I and was reinstated by Turkish troops. In 1419 the rock appears to have come into the possession of Venice, though it soon returned to the Despot. About 1401, the historian George Sphrantzes was born in the town. After the fall of Constantinople in 1453 Monemvasia held out against the threats of Sultan Mehmed II in 1458 and 1460, when it became the only remaining domain of the Despot of the Morea, Thomas Palaiologos, claimant of the Imperial throne. He had no forces to defend it; he offered it to the Sultan, and finally sold it to the Pope.

By 1464 the inhabitants found the Pope's representative feeble and the Pope unable to protect them; they admitted a Venetian garrison. The town was fairly prosperous under Venetian rule until the peace of 1502-3, in which it lost its farm lands, source of its food supply and of Malmsey wine. The food had to come by sea or from Turkish-held lands, and the cultivation of wine languished under Turkish rule. The rock was governed by the Venetians until the treaty of 1540, which cost the Republic Nauplia and Monemvasia, her last two possessions on mainland Greece. Those inhabitants who did not wish to live under Turkish rule were given lands elsewhere. The Ottomans then ruled the town until the brief Venetian recovery in 1690, then again from 1715 to 1821. It was known as "Menekşe" ("Violet" in Turkish) during Ottoman rule and was a sanjak (province) centre in the MoreaEyalet.

The commercial importance of the town continued until the Orlov Revolt (1770) in the Russo-Turkish War, which saw its importance decline severely. The town was liberated from Ottoman rule on July 23, 1821 by TzannetakisGrigorakis who entered the town with his private army during the Greek War of Independence.

Mystras or Mistras also known as Myzithras (Μυζηθρᾶς) in the Chronicle of the Morea, is a fortified town and a former municipality in Laconia, Peloponnese, Greece. Situated on Mt. Taygetos, near ancient Sparta, it served as the capital of the Byzantine Despotate of the Morea in the 14th and 15th centuries, experiencing a period of prosperity and cultural flowering. The site remained inhabited throughout the Ottoman period, when it was mistaken by Western travellers for ancient Sparta. In the 1830s, it was abandoned and the new town of Sparti was built, approximately eight kilometres to the east.

Since the 2011 local government reform it is part of the municipality Sparti, of which it is a municipal unit.In late 1248, William II of Villehardouin, ruler of the Frankish Principality of Achaea, captured Monemvasia, the last remaining Byzantine outpost on the Morea. This success was soon followed by the submission of the restive Tsakones on Mount Parnon, the Slavic Melingoi tribe of Mount Taygetos, and the inhabitants of the Mani peninsula, thereby extending his sway over all of Laconia and completing the conquest of the peninsula, which had begun in 1205, in the aftermath of the Fourth Crusade.[5] Laconia was incorporated into the princely domain, and the young prince passed the winter of 1248–49 there, touring the country and selecting sites for new fortifications such as Grand Magne and Leuktron; finally, near his residence of Lacedaemon (ancient Sparta), on a spur of Mount Taygetos, he built the fortress that came to be known as Mystras.

In September 1259, William of Villehardouin was defeated and captured, along with many of his nobles, at the Battle of Pelagonia, by the forces of the Nicaean emperor Michael VIII Palaiologos. Two years later, the Nicaeans recaptured Constantinople, putting an end to the Latin Empire and restoring the Byzantine Empire. At this point, the emperor concluded an agreement with the captive prince: William and his men would be set free in exchange for an oath of fealty, and for the cession of Monemvasia, Grand Magne, and Mystras. The handover was effected in 1262, and henceforth Mystras was the seat of the governor of the Byzantine territories in the Morea. Initially this governor (kephale) was changed every year, but after 1308 they started being appointed for longer terms.

Initially this governor (kephale) was changed every year, but after 1308 they started being appointed for longer terms.

Almost immediately on his return to the Morea, William of Villehardouin renounced his oath to the emperor, and warfare broke out between Byzantines and Franks. The first Byzantine attempts to subdue the Principality of Achaea were beaten back in the battles of Prinitsa and Makryplagi, but the Byzantines were firmly ensconced in Laconia. Warfare became endemic, and the Byzantines slowly pushed the Franks back.[8] The insecurity engendered by the raids and counter-raids caused the inhabitants of Lacedaemon to abandon their exposed city and settle at Mystras, in a new town built under the shadow of the fortress.

From 1348 until its surrender to the Ottoman Turks on 31 May 1460, Mystras was the residence of a Despot who ruled over the Byzantine Morea, known as the "Despotate of the Morea". This was the city's golden age; according to the Oxford Dictionary of Byzantium, Mystras "witnessed a remarkable cultural renaissance, including the teaching of Plethon [..], and attracted artists and architects of the highest quality".

The frescos in the Peribleptos Monastery Church, dating between 1348 and 1380, are a very rare surviving late Byzantine cycle, crucial for the understanding of Byzantine art.

Mystras was also the last centre of Byzantine scholarship; the Neoplatonist philosopher George GemistosPlethon lived there until his death in 1452. He and other scholars based in Mystras influenced the Italian Renaissance, especially after he accompanied the emperor John VIII Palaiologos to Florence in 1439. The last Byzantine emperor, Constantine XI Palaiologos, was despot at Mystras before he came to the throne. Demetrius Palaeologus the last despot of Morea, surrendered the city to the Ottoman emperor Mehmed II in 1460. As Mezistre, it was the seat of a Turkish sanjak. The Venetians occupied it from 1687 to 1715, but otherwise the Ottomans held it until 1821 and the beginning of the Greek War of Independence. It was abandoned under King Otto for the newly rebuilt town of Sparta.
