Charlemagne was crowned Emperor of the Roman People on December 25,  800 AD, by Pope Leo III, in St. Peter's Basilica, in Rome. His  empire, however, is not usually consider â¦ ed the same as the Holy  Roman Empire.    Today, the empire of which he was crowned is usually called the  Carolingian Empire.
But [38] that, too, fell, and Charlemagne entered in triumph into the capital of the Lombard kingdom. Desiderius, the last king of the Lombards, was taken prisoner, his head was shaved, and he was sent to France, there to end his days in a monastery. Thus the rule of the Lombards in Italy, which had lasted for two hundred years, came to an end. But unlike his father, Charlemagne did not hand over all his conquests to the pope. He placed the crown of Lombardy on his own head, added the kingdom to his already great territory, and henceforth called himself king of the Franks and of Lombardy. But greater than Charlemagne's conquest of the Lombards was his conquest of the Saxons.
