Books like Aix-la-Chapelle in the age of Charlemagne by Richard E. Sullivan

Jeff Sypeck’s *Becoming Charlemagne* retraces how the Frankish king Karl, crowned by Pope Leo III in 800, built a medieval empire through warfare, diplomacy, and alliances with leaders from Byzantium, the Abbasid Caliphate, and Jewish communities.

"When Charlemagne died in 814 CE, he left behind a dominion and a legacy unlike anything seen in Western Europe since the fall of Rome. Distinguished historian and author of The Middle Ages Johannes Fried presents a new biographical study of the legendary Frankish king and emperor, illuminating the life and reign of a ruler who shaped Europe's destiny in ways few figures, before or since, have equaled. Living in an age of faith, Charlemagne was above all a Christian king, Fried says. He made his court in Aix la Chapelle the center of a religious and intellectual renaissance, enlisting the Anglo Saxon scholar Alcuin of York to be his personal tutor, and insisting that monks be literate and versed in rhetoric and logic. He erected a magnificent cathedral in his capital, decorating it lavishly while also dutifully attending Mass every morning and evening. And to an extent greater than any ruler before him, Charlemagne enhanced the papacy's influence, becoming the first king to enact the legal principle that the pope was beyond the reach of temporal justice a decision with fateful consequences for European politics for centuries afterward. Though devout, Charlemagne was not saintly. He was a warrior king, intimately familiar with violence and bloodshed. And he enjoyed worldly pleasures, including physical love. Though there are aspects of his personality we can never know with certainty, Fried paints a compelling portrait of a ruler, a time, and a kingdom that deepens our understanding of the man often called "the father of Europe."-- Provided by publisher.

"In 476 AD, the last of Rome's emperors, known as 'Augustulus' was deposed by a barbarian general, the son of one of Attila the Hun's henchmen. With the imperial vestments dispatched to Constantinople, the curtain fell on the Roman empire in Western Europe, its territories divided among successor kingdoms constructed around barbarian military manpower. But, if the Roman Empire was dead, Romans across the old empire still lived, holding on to their lands, the values of their civilization, and their institutions. The conquering barbarians, witnessing the continuing psychological dominance of Rome, were ready to reignite the imperial flame and enjoy the benefits of its civilization. As Peter Heather shows in dazzling biographical portraits, each of the three greatest contenders--Theoderic, Justinian, and Charlemagne--operated with a different power base but was astonishingly successful in his own way. Though each in turn managed to put back together enough of the old Roman West to stake a plausible claim to the Western imperial title, none of their empires long outlived their founders' deaths. Not until the reinvention of the papacy in the eleventh century would Europe's barbarians find the means to establish a new Roman Empire, one that has lasted a thousand years"--
