Despotes in the context of "Despotate of the Morea"

Béla III (Hungarian: III. Béla, Croatian: Bela III., Slovak: Belo III.; c. 1148 – 23 April 1196) was King of Hungary and Croatia between 1172 and 1196. He was the second son of King Géza II and Géza's wife, Euphrosyne of Kiev. Around 1161, Géza granted Béla a duchy, which included Croatia, central Dalmatia and possibly Sirmium. In accordance with a peace treaty between his elder brother, Stephen III, who succeeded their father in 1162, and the Byzantine Emperor Manuel I Komnenos, Béla moved to Constantinople in 1163. He was renamed to Alexios, and the emperor granted him the newly created senior court title of despotes. He was betrothed to the Emperor's daughter, Maria. Béla's patrimony caused armed conflicts between the Byzantine Empire and the Kingdom of Hungary between 1164 and 1167, because Stephen III attempted to hinder the Byzantines from taking control of Croatia, Dalmatia and Sirmium. Béla-Alexios, who was designated as Emperor Manuel's heir in 1165, took part in three Byzantine campaigns against Hungary. His betrothal to the emperor's daughter was dissolved after her brother, Alexios, was born in 1169. The emperor deprived Béla of his high title, granting him the inferior rank of kaisar.

Stephen III died on 4 March 1172, and Béla decided to return to Hungary. Before his departure, he pledged that he would never make war against the Byzantine Empire. Although the Hungarian prelates and lords unanimously proclaimed Béla king, Lucas, Archbishop of Esztergom opposed his coronation because of Béla's alleged simony. Finally, the Archbishop of Kalocsa crowned him king on 18 January 1173, with Pope Alexander III's approval. Béla fought with his younger brother, Géza, whom he held in captivity for more than a decade. Taking advantage of the internal conflicts in the Byzantine Empire after Emperor Manuel's death, Béla reoccupied Croatia, Dalmatia and Sirmium between 1180 and 1181. He occupied the Principality of Halych in 1188, but it was lost within two years.

The Treaty of Edirne and the Peace of Szeged were two halves of a peace treaty between Sultan Murad II of the Ottoman Empire and King Vladislaus of the Kingdom of Hungary. Despot Đurađ Branković of the Serbian Despotate was a party to the proceedings. The treaty brought an end to the Christian crusade against the Ottomans with significant gains. Within a month Vladislaus abjured his oath at the urging of the papacy and the crusade continued. On 10 November 1444 it ended in disaster at the Battle of Varna where the crusaders were wiped out and Vladislaus killed.

The treaty was started in Edirne with discussions between Murad and Vladislaus' ambassador. Within a few days, it was sent to Szeged with Murad's ambassador, to be finalized and ratified by Vladislaus. Once it arrived, complications caused the negotiations to continue for several more days, and oaths were eventually given in Várad. The ratification took place on 15 August 1444 in Várad.

Maria Komnene (or Comnena) (Greek: Μαρία Κομνηνή, Maria Komnēnē; Constantinople, March 1152 – July 1182) was the eldest daughter of the Emperor Manuel I Komnenos by his first wife, Bertha of Sulzbach. She was known as the Porphyrogennete (Πορφυρογέννητη) or Porphyrogenita because she had been "born in the Purple Chamber", i.e. born in the Palace at Constantinople to the wife of a reigning emperor.

Maria was probably born in March 1152. According to Cinnamus, she was given the title Augusta at her birth. In 1163 she was engaged to the future King Béla III of Hungary; Manuel, no longer expecting to father a legitimate son, was at that time ready to designate Béla (whom he had given the new court dignity of despotes and had renamed "Alexios") as his eventual successor. This engagement was broken off in 1169, soon after Manuel's son Alexios was born. Maria was then engaged to King William II of Sicily, but this engagement, too, was broken off by her father. Finally, in 1179, Maria was married to Renier of Montferrat, who was renamed "John" and given the title of Caesar.

Princess Milica Hrebeljanović née Nemanjić (Serbian: Милица Немањић Хребељановић · ca. 1335 – November 11, 1405) also known as Empress (Tsaritsa) Milica, was a royal consort of Serbia by marriage to Prince Lazar, who fell in the Battle of Kosovo. After her husband's death, she took the role as queen regent of Serbia from 1389 to 1393, until her son, despot Stefan Lazarević came of age.

She later became a Serbian Orthodox nun under the name Jevgenija. She is the author of "A Mother's Prayer" (Serbian: Молитва матере) and a famous poem of mourning for her husband, My Widowhood's Bridegroom (Serbian: Удовству мојему женик).

Jovan Uglješa (Serbian Cyrillic: Јован Угљеша; fl. 1346–1371) was a Serbian medieval nobleman of the Mrnjavčević family and one of the most prominent magnates of the Serbian Empire. He held the title of despot, received from Serbian Emperor Stefan Uroš V, whose co-ruler - Serbian King Vukašin was Uglješa's brother.

Uglješa was the son of Mrnjava, a treasurer of Helen, the queen consort of Stephen Uroš I of Serbia. He held Travunija in 1346, during the rule of Stefan Dušan (1331–1355). Uglješa married Jelena (later nun Jefimija), daughter of Vojihna, the kesar of Drama. This boosted the power of Uglješa, who would later govern the region alongside his father-in-law. Vojihna died in 1360, and his lands were inherited by Uglješa. He was given the title of despotes by the widowed Serbian empress, Helena of Bulgaria, in 1365. His domain, the Principality of Serres [bg], was situated along the lower course of the Struma with Serres as seat, eventually replacing Helena in its possession. From 1368, his territory was under the religious jurisdiction of the Ecumenical Patriarchate of Constantinople. The Patriarch mentioned the "master of Raška" (another name for Serbia), Jovan Uglješa, in a letter from 1371. With the Ottoman threat rising in the Balkans, Uglješa and his brothers Vukašin Mrnjavčević and Gojko Mrnjavčević tried to oppose the Turks. Uglješa was killed on 26 September 1371 in the Battle of Maritsa. Their troops were defeated by those of Ottoman commanders Lala Shahin Pasha and Gazi Evrenos at the Battle of Maritsa in 1371. The defeat resulted in large portions of the region of Macedonia falling under Ottoman power. Additionally, Uglješa's two brothers were killed during the fight. Their courage made them heroes of Bulgarian and Serbian epic poetry.
