Theme (Byzantine district) in the context of "Chaldia"

The Uprising of Asen and Peter (Bulgarian: Въстание на Асен и Петър) was a revolt of Bulgarians and Vlachs living in Moesia and the Balkan Mountains, then the theme of Paristrion of the Byzantine Empire, caused by a tax increase. It began on 26 October 1185, the feast day of St. Demetrius of Thessaloniki, and ended with the restoration of Bulgaria with the creation of the Second Bulgarian Empire, ruled by the Asen dynasty.

Isaac II Angelus, in order to raise money for his wedding with the daughter of King Béla III of Hungary, levied a new tax which fell heavily on the population of the Haemus Mountains. They sent two leaders (Peter and Asen) to negotiate with the emperor at Kypsella (now İpsala) in Thrace. They asked to be added to the roll of the Byzantine army and to be granted land near Haemus to provide the monetary income needed to pay the tax. This was refused, and Peter and Asen were treated roughly. Their response was to threaten revolt.

The Theme of Cherson (Greek: θέμα Χερσῶνος, Thema Chersōnos), originally and formally called the Klimata (Greek: τὰ Κλίματα), was a Byzantine theme (a military-civilian province) located in the southern Crimea, headquartered at Cherson.

The theme was officially established in the early 830s and was an important centre of Black Sea commerce. Despite the destruction of the city of Cherson in the 980s, the theme recovered and prospered, enduring until it became a part of the Empire of Trebizond after the dissolution of the Byzantine Empire in 1204.

Peter II, born Theodor, also known as Theodor-Peter (Bulgarian: Теодор-Петър; died in 1197), was the first emperor or tsar of the restored Bulgarian Empire from 1185 to 1197. He hails from the Byzantine theme of Paristrion, although his exact place and date of birth are unknown.

He and his younger brothers, Asen and Kaloyan, were mentioned as Vlachs in most foreign contemporaneous sources but they were probably of a mixed Vlach, Bulgarian, and Cuman origin. In 1185, Theodor and Asen approached the Byzantine Emperor Isaac II Angelos in Thrace, demanding an estate in the Balkan Mountains. After the Emperor refused and humiliated them, they decided to incite a rebellion, taking advantage of the discontent that a new tax had caused among the Bulgarians and Vlachs. To convince their compatriots to join them, they had native prophets declare that Saint Demetrius of Thessalonica had abandoned the Romans in favour of the Bulgarians and Vlachs. Before the end of the year, Theodor was crowned Emperor of Bulgaria, taking the name Peter and adopting the insignia used only by emperors.

Ivan Asen I, also known as Asen I or John Asen I (Bulgarian: Иван Асен I; died in 1196), was emperor or tsar of Bulgaria from 1187/1188 to 1196 as co-ruler with his elder brother, Peter II. Hailing from the Byzantine theme of Paristrion, his exact place and date of birth are unknown. Most contemporaneous chronicles describe Asen and his brothers, Theodor (Peter) and Kaloyan, as Vlachs but they were probably of mixed Bulgarian, Cuman and Vlach ancestry.

In 1185, Asen and Theodor went to see the Byzantine Emperor Isaac II Angelos in Thrace to demand an estate in the Balkan Mountains. After the Emperor refused and humiliated them, the brothers persuaded their Bulgarian and Vlach compatriots to rise up against the Byzantine Empire. Before the end of the year, Theodor was crowned Emperor of Bulgaria, taking the name Peter. After Isaac II defeated them in early 1186, Asen and Peter fled north over the Danube but returned in the autumn, accompanied by Cuman reinforcements. They captured Paristrion and began pillaging the nearby Byzantine territories.

Hierocles (Greek: Ἱεροκλῆς Hierokles) was a Byzantine geographer of the sixth century and the attributed author of the Synecdemus or Synekdemos, which contains a table of administrative divisions of the Byzantine Empire and lists of the cities of each. The work is dated to the reign of Justinian but prior to 535, as it divides the 912 listed cities in the Empire among 64 Eparchies. The Synecdemus is thus one of the most invaluable monuments which we have to study the political geography of the sixth century East. The work of Hierocles along with that of Stephanus of Byzantium were the principal sources of Constantine VII's work on the Themes (De Thematibus). Hierocles was published by Parthey (Hieroclis Synecdemus; Berlin, 1866) then in a corrected text, by A. Burckhardt in the Teubner series (Hieroclis Synecdemus; Leipzig, 1893). The most recent major publication was by E. Honigmann (Le Synekdèmos d'Hiéroklès et l'opuscule géographique de Georges de Chypre; Brussels, 1939).

The Synecdemus of Hierocles should not be confused with a Greek Orthodox prayer book by the same name.

The Theme of Dalmatia (Greek: θέμα Δαλματίας/Δελματίας, thema Dalmatias/Delmatias) was a Byzantine theme (a military-civilian province) on the eastern coast of the Adriatic Sea in Southeastern Europe, headquartered at Jadera (later called Zara, today's Zadar).

The Theme of Mylasa and Melanoudion (Greek: θέμα Μυλά[σ]σης και Μελανουδίου) was a Byzantine province (thema) in southwestern Asia Minor (modern Turkey) in the 12th and 13th centuries.

It is first attested in 1127/1128, and was probably created sometime after 1110, either by Alexios I Komnenos (r. 1081–1118) or by his son and successor John II Komnenos (r. 1118–1143), out of territory regained from the Seljuk Turks during the 1090s. Originally named simply the Theme of Mylasa, it was renamed after its seat moved from Mylasa (modern Milas) to the town of Melanoudion – as yet not conclusively identified, it lay south of Miletus – sometime in ca. 1150–1175.
