Byzantine Emperor in the context of "Council of Hieria"

Shkodër (/ˈʃkoʊdər/ SHKOH-dər, Albanian: [ˈʃkɔdəɾ]; Albanian definite form: Shkodra; historically known as Scodra or Scutari) is the fifth-most-populous city of Albania and the seat of Shkodër County and Shkodër Municipality. Shkodër has been continuously inhabited since the Early Bronze Age (c. 2250–2000 BC), and has roughly 2,200 years of recorded history. The city sprawls across the Plain of Mbishkodra between the southern part of Lake Shkodër and the foothills of the Albanian Alps on the banks of the Buna, Drin and Kir rivers. Due to its proximity to the Adriatic Sea, Shkodër is affected by a seasonal Mediterranean climate with continental influences.

An urban settlement called Skodra was founded by the Illyrian tribe of Labeatae in the 4th century BCE. It became the capital of the Illyrian kingdom under the Ardiaei and Labeatae and was one of the most important cities of the Balkans in ancient times. It has historically developed on a 130 m (430 ft) hill strategically located in the outflow of Lake Shkodër into the Buna. The Romans annexed the city after the third Illyrian War in 168 BC, when the Illyrian king Gentius was defeated by the Roman force of Anicius Gallus. In the 3rd century AD, Shkodër became the capital of Praevalitana, due to the administrative reform of the Roman Emperor Diocletian. With the spread of Christianity in the 4th century AD, the Archdiocese of Scodra was founded and was assumed in 535 by Byzantine Emperor Justinian I.

The Arab Muslim conquest of Sicily began in June 827 and lasted until 902, when the last major Byzantine stronghold on the island, Taormina, fell. Isolated fortresses remained in Byzantine hands until 965, but the island was henceforth under Arab Muslim rule until conquered in turn by the Normans in the 11th century.

Although Sicily had been raided by the Muslim Arabs since the mid-7th century, these raids did not threaten Byzantine control over the island, which remained a largely peaceful backwater. The opportunity for the Aghlabid emirs of Ifriqiya (present-day Tunisia) came in 827, when the commander of the island's fleet, Euphemius, rose in revolt against the Byzantine Emperor Michael II. Defeated by loyalist forces and driven from the island, Euphemius sought the aid of the Aghlabids, an Arab dynasty. The latter regarded this as an opportunity for expansion and for diverting the energies of their own fractious military establishment and alleviating the criticism of the Islamic scholars by championing jihad, and dispatched an army to aid him. Following the Arab landing on the island, Euphemius was quickly sidelined. An initial assault on the island's capital, Syracuse, failed, but the Muslims were able to weather the subsequent Byzantine counter-attack and hold on to a few fortresses. With the aid of reinforcements from Ifriqiya and Umayyad al-Andalus, in 831 they took Palermo, which became the capital of the new Arab-Muslim province.

The Corpus Juris (or Iuris) Civilis ("Body of Civil Law") is the modern name for a collection of fundamental works in jurisprudence, enacted from 529 to 534 by order of Byzantine Emperor Justinian I. It is also sometimes referred to metonymically after one of its parts, the Code of Justinian.

The work as planned had three parts: the Code (Codex) is a compilation, by selection and extraction, of imperial enactments to date; the Digest or Pandects (the Latin title contains both Digesta and Pandectae) is an encyclopedia composed of mostly brief extracts from the writings of Roman jurists; and the Institutes (Institutiones) is a student textbook, mainly introducing the Code, although it has important conceptual elements that are less developed in the Code or the Digest. All three parts, even the textbook, were given force of law. They were intended to be, together, the sole source of law; reference to any other source, including the original texts from which the Code and the Digest had been taken, was forbidden. Nonetheless, Justinian found himself having to enact further laws; today these are counted as a fourth part of the Corpus, the Novellae Constitutiones (Novels, literally New Laws).

The Battle of Kleidion (Ancient Greek: Κλειδίον; or Clidium, after the medieval name of the village of Klyuch, lit. 'key'; also known as the Battle of Belasitsa) took place on 29 July 1014, between the Byzantine Empire and the Bulgarian Empire. It was the culmination of the nearly half-century struggle between the Byzantine Emperor Basil II and the Bulgarian emperor Samuel in the late 10th and early 11th centuries. The result was a decisive Byzantine victory.

The battle took place in the valley between the mountains of Belasitsa and Ograzhden, near the modern Bulgarian village of Klyuch. The decisive encounter occurred on 29 July with an attack in the rear by a force under the Byzantine general Nikephoros Xiphias, who had infiltrated the Bulgarian positions. The ensuing battle was a major defeat for the Bulgarians. Thousands of Bulgarian soldiers were captured and blinded by order of Basil II, who would subsequently be known as the "Bulgar-Slayer". Samuel survived the battle, but died two months later from a heart attack, reportedly brought on by the sight of his blind soldiers.

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.

Romanos II (Greek: Ῥωμανός, romanized: Rōmanos; 938 – 15 March 963) was Byzantine Emperor from 959 to 963. He succeeded his father Constantine VII at the age of twenty-one and died suddenly and mysteriously four years later. His wife Theophano helped their sons Basil II and Constantine VIII ultimately succeed him in 976.

Byzantine Anatolia refers to the peninsula of Anatolia (located in present-day Turkey) during the rule of the Byzantine Empire. Anatolia was of vital importance to the empire following the Muslim invasion of Syria and Egypt during the reign of the Byzantine Emperor Heraclius in the years 634–645 AD. Over the next two hundred and fifty years, the region suffered constant raids by Arab Muslim forces raiding mainly from the cities of Antioch, Tarsus, and Aleppo near the Anatolian borders. However, the Byzantine Empire maintained control over the Anatolian peninsula until the High Middle Ages (years 1080s), when imperial authority in the area began to collapse.

The Byzantine Empire re-established control over parts of Anatolia during the First Crusade, and following the sack of Constantinople during the Fourth Crusade, Anatolia became the heartland of the successor states of the Empire of Nicaea and Empire of Trebizond. Following the retaking of Constantinople in 1261, the region gradually passed out of Byzantine control and into the hands of the Ottoman Turks as the empire gradually crumbled. The last Byzantine fortress of Philadelphia fell in 1399, and the last Byzantine presence in the area at Trapezus ended in 1461 with the fall of Trebizond.

Isaac II Angelos or Angelus (Greek: Ἰσαάκιος Κομνηνός Ἄγγελος, romanized: Isaákios Komnēnós Ángelos; September 1156 – 28 January 1204) was Byzantine Emperor from 1185 to 1195, and co-Emperor with his son Alexios IV Angelos from 1203 to 1204. In an 1185 revolt against the Emperor Andronikos Komnenos, Isaac seized power and rose to the Byzantine throne, establishing the Angelos family as the new imperial dynasty.

His father Andronikos Doukas Angelos was a military leader in Asia Minor (c. 1122 – aft. 1185) who married Euphrosyne Kastamonitissa (c. 1125 – aft. 1195). Andronikos Doukas Angelos was the son of Constantine Angelos and Theodora Komnene (b. 15 January 1096/1097), the youngest daughter of Emperor Alexios I Komnenos and Irene Doukaina. Thus Isaac was a member of the extended imperial clan of the Komnenoi.
