Despotate of Arta
The Despotate of Arta was a despotate established by Albanian rulers during the 14th century, after the defeat of the local Despot of Epirus, Nikephoros II Orsini, by Albanian tribesmen in the Battle of Achelous in 1359. The Despotate ceased to exist in 1416, when it passed to Carlo I Tocco.
History
Creation
In the late spring of 1359, Nikephoros II Orsini, the last despot of Epirus of the Orsini dynasty, fought against the Albanians near river Acheloos, Aetolia. The Albanians won the battle under Karl Thopia and managed to create two new states in the southern territories of the Despotate of Epirus. Because a number of Albanian lords actively supported the successful Serbian campaign in Thessaly and Epirus, the Serbian Tsar granted them specific regions and offered them the Byzantine title of despotes in order to secure their loyalty.By the late 1360s, two Albanian principalities had emerged: the first with its capital in Arta under Pjetër Losha, and the second, centered in Angelokastron, under Gjin Bua Shpata. After the death of Pjetër Losha in 1374, the Albanian despotates of Arta and Angelocastron were united under the rule of Gjin Bua Shpata.
On April 1378 the Grand Master of the Knights Hospitaller, Juan Fernández de Heredia set about to take Arta but failed and was captured in battle by Gjin Bua Shpata. Herendia was sold by Shpata to the Ottoman Turks for a huge prize. Thomas II Preljubović, the Despot of Epirus offered valuable help during the battle, however this alliance didn't last for long.
The territory of this despotate at its greatest extent was from the Corinth Gulf to Acheron River in the North, neighboring with the Principality of Gjirokastër of Gjon Zenebishi, another state created in the area of the Despotate of Epirus. The Despotate of Epirus managed to control in this period only the eastern part of Epirus, with its capital in Ioannina. During this period the Despot of Epirus Thomas II Preljubović was in an open conflict with Gjin Shpata. In 1375, Gjin Bua Shpata started an offensive in Ioannina, but he could not invade the city. Although Shpata married with Thomas' sister, Helena, their war did not stop.
