 Las Casas appointed a vicar for his diocese and set out for Europe in December 1546, arriving in Lisbon in April 1547 and in Spain on November 1547.Las Casas returned to Spain, leaving behind many conflicts and unresolved issues.Arriving in Spain he was met by a barrage of accusations, many of them based on his Confesionario and its 12 rules, which many of his opponents found to be in essence a denial of the legitimacy of Spanish rule of its colonies, and hence a form of treason.
