Leo Rhabduchus
Leo Rhabdouchos or Rhabduchus ( el, ; fl. 917) was a Byzantine nobleman and diplomat. Biography Leo was apparently a relative to the ruling Macedonian dynasty, and a brother-in-law of the famed diplomat Leo Choirosphaktes. In 917, he was governor (''strategos'') of the theme of Dyrrhachium, and was sent to the Serbian ruler Petar Gojniković (r. 892–917) to persuade him to attack Simeon I of Bulgaria (r. 893–927), with whom the Byzantines were at war. Leo was successful, but the Serbian attack failed and Petar was taken captive. From the ''De Administrando Imperio'' of Emperor Constantine VII Porphyrogennetos (r. 913–959), it is also known that Leo was later promoted from his rank of ''protospatharios'' to that of ''magistros'', and became Logothete of the Drome The ( gr, λογοθέτης τοῦ δρόμου), in English usually rendered as Logothete of the Course/Drome/ or Postal Logothete, was the head of the department of the Public Post ( la, cursus publicus, gr ...

Byzantine
The Byzantine Empire, also referred to as the Eastern Roman Empire or Byzantium, was the continuation of the Roman Empire primarily in its eastern provinces during Late Antiquity and the Middle Ages, when its capital city was Constantinople. It survived the fragmentation and fall of the Western Roman Empire in the 5th century AD and continued to exist for an additional thousand years until the fall of Constantinople to the Ottoman Empire in 1453. During most of its existence, the empire remained the most powerful economic, cultural, and military force in Europe. The terms "Byzantine Empire" and "Eastern Roman Empire" were coined after the end of the realm; its citizens continued to refer to their empire as the Roman Empire, and to themselves as Romans—a term which Greeks continued to use for themselves into Ottoman times. Although the Roman state continued and its traditions were maintained, modern historians prefer to differentiate the Byzantine Empire from Ancient Rome a ...

De Administrando Imperio
''De Administrando Imperio'' ("On the Governance of the Empire") is the Latin title of a Greek-language work written by the 10th-century Eastern Roman Emperor Constantine VII. The Greek title of the work is ("To yown son Romanos"). It is a domestic and foreign policy manual for the use of Constantine's son and successor, the Emperor Romanos II. It is a prominent example of Byzantine encyclopaedism. Author and background The emperor Constantine VII “Porphyrogenitus” (905–959) was only surviving son of the emperor Leo VI the Wise (886–912). Leo VI gave the crown to young Constantine VII in 908 and he became the co-emperor. Leo VI died in May 912, and his brother and co-emperor Alexander became the ruler of Constantinople, but Alexander died in 913. Constantine VII was too young to rule on his own, and the governorship was created. Later in May 919 Constantine VII married Helena Lekapene, daughter of Romanos Lekapenos. In December 920, Romanos I Lekapenos (920–944) wa ...

10th-century Byzantine People
1 (one, unit, unity) is a number representing a single or the only entity. 1 is also a numerical digit and represents a single unit of counting or measurement. For example, a line segment of ''unit length'' is a line segment of length 1. In conventions of sign where zero is considered neither positive nor negative, 1 is the first and smallest positive integer. It is also sometimes considered the first of the infinite sequence of natural numbers, followed by  2, although by other definitions 1 is the second natural number, following  0. The fundamental mathematical property of 1 is to be a multiplicative identity, meaning that any number multiplied by 1 equals the same number. Most if not all properties of 1 can be deduced from this. In advanced mathematics, a multiplicative identity is often denoted 1, even if it is not a number. 1 is by convention not considered a prime number; this was not universally accepted until the mid-20th century. Additionally, 1 is ...

Logothete Of The Drome
The ( gr, λογοθέτης τοῦ δρόμου), in English usually rendered as Logothete of the Course/Drome/ or Postal Logothete, was the head of the department of the Public Post ( la, cursus publicus, gr, δημόσιος δρόμος, demosios dromos, or simply , ), and one of the most senior fiscal ministers (logothetes) of the Byzantine Empire. History and functions The office of the is explicitly attested for the first time in circa 762, but traces its origins to the officials supervising the Public Post in Late Antiquity. Until the late 4th century, the administration of the Roman Empire's Public Post was a responsibility of the praetorian prefectures. Due to the abuse of the Post and its privileges by the officials of the praetorian prefecture, in the late 4th century the oversight over the Post passed to the , while the day-to-day administration remained in the hands of the praetorian prefecture. As a result, an official known as the , the inspector of the Publi ...

Magistros
The ''magister officiorum'' (Latin literally for "Master of Offices", in gr, μάγιστρος τῶν ὀφφικίων, magistros tōn offikiōn) was one of the most senior administrative officials in the Later Roman Empire and the early centuries of the Byzantine Empire. In Byzantium, the office was eventually transformed into a senior honorary rank, simply called ''magistros'' (μάγιστρος), until it disappeared in the 12th century. History and functions Late Roman Empire Although some scholars have supported its creation under Emperor Diocletian (), the office can first be definitely traced to the year 320, during the reign of Roman emperor Constantine the Great (), but was probably created sometime soon after 312–13, probably as part of an effort to limit the power of the praetorian prefect (''praefectus praetorio'') the Roman emperor's chief administrative official. The ''magister'' was first given command of the palace guard, the ''Scholae Palatinae''. He was ...

Protospatharios
''Prōtospatharios'' ( el, πρωτοσπαθάριος) was one of the highest court dignities of the middle Byzantine period (8th to 12th centuries), awarded to senior generals and provincial governors, as well as to foreign princes. History The meaning of the title, "first ''spatharios''", indicates its original role as leader of the order (''taxis'') of the ''spatharioi'', the imperial bodyguards, was already attested in the 6th century. Probably under the Heraclians, the rank became an honorary dignity (Greek: δια βραβείου ἀξία, ''dia brabeiou axia''), and was henceforth bestowed to high-ranking theme commanders, senior court officials, and allied rulers.. The first concrete reference to a ''prōtospatharios'' occurs in the ''Chronicle'' of Theophanes the Confessor, who records "Sergios, ''prōtospatharios'' and '' stratēgos'' of Sicily" in 718. In the late 9th century, the ''prōtospatharios'' is recorded as ranking below the ''patrikios'' and above the ''di ...

Constantine VII Porphyrogennetos
Constantine VII Porphyrogenitus (; 17 May 905 – 9 November 959) was the fourth Emperor of the Macedonian dynasty of the Byzantine Empire, reigning from 6 June 913 to 9 November 959. He was the son of Emperor Leo VI and his fourth wife, Zoe Karbonopsina, and the nephew of his predecessor Alexander. Most of his reign was dominated by co-regents: from 913 until 919 he was under the regency of his mother, while from 920 until 945 he shared the throne with Romanos Lekapenos, whose daughter Helena he married, and his sons. Constantine VII is best known for the ''Geoponika'' (τά γεοπονικά), an important agronomic treatise compiled during his reign, and three, perhaps four, books; '' De Administrando Imperio'' (bearing in Greek the heading Πρὸς τὸν ἴδιον υἱὸν Ῥωμανόν), '' De Ceremoniis'' (Περὶ τῆς Βασιλείου Τάξεως), '' De Thematibus'' (Περὶ θεμάτων Άνατολῆς καὶ Δύσεως), and ''Vita Basilii'' ...

Bulgarian–Serbian Wars Of 917–924
The Bulgarian–Serbian wars of 917–924 ( bg, Българо–сръбски войни от 917–924) were a series of conflicts fought between the Bulgarian Empire and the Principality of Serbia as a part of the greater Byzantine–Bulgarian war of 913–927. After the Byzantine army was annihilated by the Bulgarians in the battle of Achelous, the Byzantine diplomacy incited the Principality of Serbia to attack Bulgaria from the west. The Bulgarians dealt with that threat and replaced the Serbian prince with a protégé of their own. In the following years the two empires competed for control over Serbia. In 924 the Serbs rose again, ambushed and defeated a small Bulgarian army. That turn of events provoked a major retaliatory campaign that ended with the annexation of Serbia in the end of the same year. Prelude Soon after Simeon I (r. 893–927) ascended to the throne, he successfully defended Bulgaria's commercial interests, acquired territory between the Black Sea and ...
