Coenwulf Of Mercia
Coenwulf (; also spelled Cenwulf, Kenulf, or Kenwulph; la, Coenulfus) was the King of Mercia from December 796 until his death in 821. He was a descendant of King Pybba, who ruled Mercia in the early 7th century. He succeeded Ecgfrith, the son of Offa; Ecgfrith only reigned for five months, and Coenwulf ascended the throne in the same year that Offa died. In the early years of Coenwulf's reign he had to deal with a revolt in Kent, which had been under Offa's control. Eadberht Præn returned from exile in Francia to claim the Kentish throne, and Coenwulf was forced to wait for papal support before he could intervene. When Pope Leo III agreed to anathematise Eadberht, Coenwulf invaded and retook the kingdom; Eadberht was taken prisoner, was blinded, and had his hands cut off. Coenwulf also appears to have lost control of the kingdom of East Anglia during the early part of his reign, as an independent coinage appears under King Eadwald. Coenwulf's coinage reappears in 805, indic ...

Lothair I
Lothair I or Lothar I (Dutch and Medieval Latin: ''Lotharius''; German: ''Lothar''; French: ''Lothaire''; Italian: ''Lotario'') (795 – 29 September 855) was emperor (817–855, co-ruling with his father until 840), and the governor of Bavaria (815–817), King of Italy (818–855) and Middle Francia (840–855). Lothair was the eldest son of the Carolingian emperor Louis the Pious and his wife Ermengarde of Hesbaye, daughter of Ingerman the duke of Hesbaye. On several occasions, Lothair led his full-brothers Pepin I of Aquitaine and Louis the German in revolt against their father to protest against attempts to make their half-brother Charles the Bald a co-heir to the Frankish domains. Upon the father's death, Charles and Louis joined forces against Lothair in a three-year civil war (840–843). The struggles between the brothers led directly to the breakup of the Frankish Empire assembled by their grandfather Charlemagne, and laid the foundation for the development of moder ...

Thionville (; ; german: Diedenhofen ) is a city in the northeastern French department of Moselle. The city is located on the left bank of the river Moselle, opposite its suburb Yutz. History Thionville was settled as early as the time of the Merovingians. After the fall of the Western Roman Empire, the region was inhabited by the Germanic Alamanni. It was known in the Latin of that era as ''Theudonevilla'' or ''Totonisvilla''. King Pepin the Short had a royal palace constructed here. The Synod of Thionville was held here beginning on February 2, 835. It reinstated Emperor Louis the Pious and reversed his former conviction on crimes — none of which he actually committed — and deposed the Archbishop of Rheims, Ebbo. The Synod was composed of 43 bishops. On February 28, 835, in Mainz, Ebbo admitted that Louis had not committed the crimes of which he had been indicted and for which he had been deposed as Holy Roman Emperor. From the 10th century onward, the area ...

Abbasid Caliphate
The Abbasid Caliphate ( or ; ar, الْخِلَافَةُ الْعَبَّاسِيَّة, ') was the third caliphate to succeed the Islamic prophet Muhammad. It was founded by a dynasty descended from Muhammad's uncle, Abbas ibn Abdul-Muttalib (566–653 CE), from whom the dynasty takes its name. They ruled as caliphs for most of the caliphate from their capital in Baghdad in modern-day Iraq, after having overthrown the Umayyad Caliphate in the Abbasid Revolution of 750 CE (132  AH). The Abbasid Caliphate first centered its government in Kufa, modern-day Iraq, but in 762 the caliph Al-Mansur founded the city of Baghdad, near the ancient Babylonian capital city of Babylon. Baghdad became the center of science, culture and invention in what became known as the Golden Age of Islam. This, in addition to housing several key academic institutions, including the House of Wisdom, as well as a multiethnic and multi-religious environment, garnered it a worldwide reputation as the ...
