9. This Medieval Monarch Slept With His Live Sister and Dead Wife
Medieval Europe’s greatest monarch was probably Charlemagne, who unified much of western and central Europe into what became known as the Carolingian Empire. In 800, he was crowned by Pope Leo III as “Emperor of the Romans” – the first in a long line of Holy Roman Emperors that lasted for over a thousand years, until Napoleon Bonaparte abolished the Holy Roman Empire in 1806. Charlemagne was also a weirdo, who was into incest and necrophilia. He had an incestuous relationship with his sister Gillen, and fathered upon her a son/ nephew, named Roland.
Sleeping with his sister was not the worst of it: Charlemagne also reportedly had a thing for sleeping with corpses. A variety of texts from the ninth century refer to Charlemagne repeatedly engaging in, but refusing for a long time to confess to, some “unspeakable sin“. He eventually got it off his chest and sought absolution for what some modern scholars think was a predilection for necrophilia. That gave rise to legends in which Charlemagne’s partiality to corpses extended from sexually satisfying his lusts with random corpses, to sleeping with his wife’s corpse after her death.
