The Roman emperor who married his mother was Gaius Julius Caesar Augustus Germanicus, more commonly known as Caligula.
Caligula's reign was marked by a series of controversial and often brutal acts. His marriage to his mother, Agrippina the Younger, was one of the most shocking and scandalous events of his reign.
While the exact nature of their relationship is debated by historians, it is generally believed that Caligula's marriage to his mother was a political maneuver designed to consolidate his power and legitimize his rule.
Caligula's marriage to Agrippina the Younger was a highly unusual event in Roman history. Roman society placed a strong emphasis on family ties and the preservation of social order. Incest was considered a taboo and was strictly forbidden.
Caligula's reign was short-lived, and he was assassinated in 41 AD. However, his marriage to his mother remains a subject of fascination and debate among historians and the general public.
