1. 800: Carolingians at Aachen
Aachen (Aix-la-Chapelle) is a city and a district in Rhenish Prussia, situated in a fertile hollow watered by the Wurm River, 39 miles southwest of Cologne.   The western boundaries of this district adjoin with Belgium and Holland.
Aachen is known for its excellent mineral springs and central to a coal and manufacturing region and rich in historical associations.
Charlemagne (Carolus Magnus), meaning Charles the Great) was King of the Franks  from 768 to his death. He expanded the Frankish kingdoms into an Empire that incorporated much of Western and Central Europe. During his reign, he conquered Italy and was crowned Imperator Augustus by Pope Leo III in 800 in an attempted revival of the Roman Empire of the West.  Through his foreign conquests and internal reforms, Charlemagne helped define Western Europe.   He  spent the first portion of his reign extending his rule, conquering the Avars, Pannonia, Britanny, northern Spain, and Bavaria. In 800 the pope crowned Charlemagne Holy Roman Emperor in the West. Throughout his reign Charlemagne was an advocate of the papacy, mentor of reformers, friend of monasticism, and a patron of learning. His palace school at Aachen became a center for training civil administrators and ecclesiastical reformers. In view of this modern scholars often speak of a Carolingian renaissance. Several synods held during the reign of Charlemagne sought to combat heresy and standardize faith and piety
The end of his reign was troubled by raids by the norsemen. His son, Louis I, was named co-emperor in 813 and succeeded on his father's death. Charlemagne's legend soon enhanced and distorted his actual achievements, and he became the central figure of a medieval romance cycle.
Charlemagne, who was likely born in Aachen, (777- 786) built a palace within the city, and made it one of the most important cities in the empire.
German emperors were crowned at Aachen, from Louis the Pious (813), to Ferdinand I (1531).
