Penance is a main topic in Louis the Pious's reign, as Mayke de Jong's book on the crisis of the late 820s and early 830s brilliantly shows. The most dramatic moment is the emperor's deposition in 833, which led to vivid discussion among the political elite. This was not the first time Louis publicly acknowledged his errors, since he had already done so in 822 at Attigny, which was associated with political success in Charlemagne's time. This was the place Louis chose for a drawing of the balance of the first years of his government and the reform he initiated. Louis's penance took place at a crucial moment of his reign because he had to change his politics in consequence of his calling back to court some of Charlemagne's main counsellors.
