 Although Papal coronation was not necessary to confirm the Imperial title, Charles V was crowned in the city of Bologna by Pope Clement VII in the medieval fashion.Charles V accumulated a large number of titles due to his vast inheritance of Burgundian, Spanish, and Austrian realms.Following the pacts of Worms (21 April 1521) and Brussels (7 February 1522), he secretely gave the Austrian lands to his younger brother Ferdinand and elevated him to the status of Archduke.
