Glarentza (Greek: Γλαρέντζα), also known as or Clarenia, Clarence, or Chiarenza, was a medieval town located near the site of modern Kyllini in Elis, at the westernmost point of the Peloponnese peninsula in southern Greece.
Glarentza was founded in the mid-13th century by William II of Villehardouin (ruled 1246–78), the ruler of the Principality of Achaea,[1] a Frankish state established after the Fourth Crusade and encompassing the Peloponnese or Morea peninsula in southern Greece.
[2] Its Frankish foundation is evident in its name, Clarence or Clairence in French, Chiarenza[3] or Clarenza in Italian, Clarentia or Clarencia in Latin, rendered Κλαρέντσα (Klarentsa), Κλαρίντζα (Klarintza), or Γλαρέντζα (Glarentza) in contemporary Greek documents.
[4] The medieval town was located a bit further west of the modern village of Kyllini, on the northern tip of a headland that forms the westernmost point of the Peloponnese.
[5] As described in the town's Greek Ministry of Culture website, Glarentza "rapidly established itself as the most important financial and urban centre of the Crusader principality, with an international renown",[1] while according to the medievalist Antoine Bon, it was "the agglomeration which should most resemble, by its activity, a city in the modern sense of the word".
[12] In June 1315, Glarentza was captured by the Aragonese troops of the infante Ferdinand of Majorca, who claimed the princely title of Achaea for himself by virtue of his marriage to Isabella of Sabran, granddaughter of William II of Villehardouin.
Ferdinand made Glarentza his residence, and soon seized all of Elis, aided by the defection of several Achaean barons dissatisfied with the Principality's rule by the Angevins of Naples.
[13][14] Ferdinand began minting coins with his name—the rarest issues of the Glarentza mint—but his reign was cut short with the arrival of the legitimate claimants, Matilda of Hainaut and Louis of Burgundy.
[1] At that time, Achaea, under Prince Centurione II Zaccaria (ruled 1404–30), found itself endangered by the attacks of the Byzantines of the Despotate of the Morea on the one hand and the expansionist designs of the Tocco family of Cephalonia and Zakynthos on the other.
A truce was concluded in 1418, but in the same year, an Italian adventurer, Olivier Franco, seized the town, which in 1421 he sold to Carlo I Tocco, Leonardo's elder brother.
[19][20] With Glarentza in their hands, the Tocchi now began to openly pursue their aspirations in the Peloponnese, and attacked the territories of the Latin Archbishop of Patras Stephen Zaccaria, Centurione's brother.
[1] Although nearby Chlemoutsi continued to play a role as a military stronghold until the 19th century—it was garrisoned by the Venetians during the Ottoman–Venetian War of 1463–79, and attacked by the Knights of Malta in 1620[26]—Glarentza itself seems to have rapidly fallen into obscurity under the Ottomans, apparently declining as the maritime links with Italy were severed.
[29] However, this view was conclusively rejected already in 1846 by the military officer and antiquarian William Martin Leake, who pointed out that at no time did English royalty hold Moreote titles, and that "Clarence" originates from Clare, Suffolk, and not Glarentza.
