Byzantine emperors in the context of "Papal States"

Basileus (Ancient Greek: βασιλεύς) is a Greek term and title that has signified various types of monarchs throughout history. In the English-speaking world, it is perhaps most widely understood to mean 'monarch', referring to either a 'king' or an 'emperor'. The title was used by sovereigns and other persons of authority in ancient Greece (especially during the Hellenistic period), the Byzantine emperors, and the kings of modern Greece. The name Basileios (Basil), deriving from the term basileus, is a common given name in the Eastern Orthodox Church and Syriac Orthodox Church for the Maphrian.

The feminine forms are basileia (βασίλεια), basilissa (βασίλισσα), basillis (βασιλίς), or the archaic basilinna (βασιλίννα), meaning 'queen' or 'empress'. The related term basileia (βασιλεία) has meanings such as 'sovereignty', 'royalty', 'kingdom', 'reign', 'dominion' and 'authority'.

Autokrator or Autocrator (Ancient Greek: αὐτοκράτωρ, romanized: autokrátōr, lit. 'self-ruler', from αὐτός, autós, 'self' + κράτος, krátos, 'dominion') is a Greek epithet applied to an individual who is unrestrained by superiors. It has been applied to military commanders-in-chief as well as Roman and Byzantine emperors as the translation of the Latin title imperator. Its connection with Byzantine and Russian-style absolutism gave rise to the modern terms autocracy and autocrat.

Euphrosyne Kastamonitissa (Greek: Εύφροσύνη Κασταμονίτισσα) was a Byzantine noblewoman of the Kastamonites family, a wife of Andronikos Doukas Angelos (a cousin of the ruling Komnenos dynasty) and mother of the two future Byzantine emperors from the Angelos family: Isaac II Angelos and Alexios III Angelos.

The Byzantine Empire was ruled by the Isaurian dynasty (or Syrian dynasty) from 717 to 802. The Isaurian emperors were successful in defending and consolidating the empire against the caliphates after the onslaught of the early Muslim conquests, but were less successful in Europe, where they suffered setbacks against the Bulgars, had to give up the Exarchate of Ravenna, and lost influence over Italy and the papacy to the growing power of the Franks.

The Isaurian dynasty is chiefly associated with Byzantine iconoclasm, an attempt to restore divine favour by purifying the Christian faith from all veneration of figural Christian iconography, which resulted in considerable internal turmoil.

Pendilia (singular pendilium; from Latin pendulus, hanging) or pendoulia (the Greek equivalent), are pendants or dangling ornaments hanging from a piece of metalwork such as a crown, votive crown, crux gemmata, or kamelaukion, and are a feature of Early Medieval goldsmith work. On crosses the pendilia may include the letters alpha and omega, and on votive offerings, which were often designed to be hung over altars and where pendilia are at their largest and most spectacular, they may spell out whole words (see illustration).

The term is commonly used in coin collecting. Pendilia are depicted on coins as jewels or pearls hanging from the sides of the crown, and occur frequently on coins of Byzantine emperors. The pendilia which hung from the Emperors' crowns began with Marcian. Although the years saw the styles of crown change, the pendilia remained, at least through Manuel II Palaiologos. Surviving crowns with pendilia include the Holy Crown of Hungary and many votive crowns of the Treasure of Guarrazar from Visigothic Spain.

The Varangian Guard (Greek: Τάγμα τῶν Βαράγγων, romanized: Tágma tōn Varángōn) was an elite unit of the Byzantine army from the 10th to the 14th century who served as personal bodyguards to the Byzantine emperors. The Varangian Guard was known for being primarily composed of recruits from Northern Europe, including mainly Norsemen from Scandinavia but also Anglo-Saxons from England. The recruitment of distant fighters from outside Byzantium to serve as the emperor's personal guard was pursued as a deliberate policy, as they lacked local political loyalties and could be counted upon to suppress revolts by disloyal Byzantine factions.

The Rus' provided the earliest members of the Varangian Guard. They were in Byzantine service from as early as 874. The Guard was first formally constituted under Emperor Basil II in 988, following the Christianization of Kievan Rus' by Vladimir I of Kiev. Vladimir, who had recently taken control of Kiev with an army of Varangian warriors, sent 6,000 men to Basil as part of a military assistance agreement. Basil's distrust of the native Byzantine guardsmen, whose loyalties often shifted with fatal consequences, as well as the proven loyalty of the Varangians, many of whom had previously served in Byzantium, led the Emperor to employ them as his personal guardsmen.
