Overview
Engelberga (or Angilberga, died between 896 and 901) was the wife of Emperor Louis II and thus Carolingian empress to his death on 12 August 875. As empress, she exerted a powerful influence over her husband.
Engelberga was probably the daughter of Adelchis I of Spoleto and a member of one of the most powerful families in the Kingdom of Italy at that time, the Supponids.
Born around 830, Engelberga probably spent her youth in Pavia. She married Louis II in 860, after being his concubine for roughly ten years, but did not play a role in political life until after the death of his father, Lothair I, in 855. Upon his death, Lothair's kingdom was divided between his three sons and, as the eldest, Louis received Italy and the title of emperor. Engelberga had far more political influence than was usual of a queen, partially due to Louis' love for her. Engelberga's active participation in politics was unusual, when queens were typically consigned to the domestic sphere.
In 856, the imperial couple were hosted in Venice by Doge Pietro Tradonico and his son Giovanni Tradonico. A few years later, Engelberga began to exert her influence in a conflict between Pope Nicholas I and Archbishop John of Ravenna. Seen as insubordinate by the Pope, John was thrice summoned to appear before a papal tribunal. Instead, he took refuge in the imperial court at Pavia, where Engelberga attempted to intervene with Rome on his behalf. Though ultimately unsuccessful, the incident was the beginning of Engelberga's efforts to assert her influence as empress.
