In 833, Judith of Bavaria and her son Charles the Bald were placed in monasteries following a successful revolt against Louis I (the Pious) by his three eldest sons.12

During the confrontation at the "Field of Lies" near Colmar, Louis was abandoned by his followers, deposed, and forced by his son Lothar I to perform public penance. The placement of Judith and Charles in monasteries was a consequence of this power shift, as the rebellious faction sought to dismantle the influence of the emperor's second wife and secure the succession in favor of the older sons, thereby undermining the emperor's efforts to create a kingdom for Charles. This arrangement was temporary, however, as the coalition of brothers soon fractured, leading to the restoration of Louis to the throne and the eventual return of his wife and son in 834.132
