Lothair was accompanied by a modest troop contingent as most men were garrisoned in Germany to counter Staufer aggression. He carefully avoided hostilities but attempted to besiege Milan, which, however, failed. Eventually he arrived in Rome. As Anacletus controlled St. Peter, Lothair's imperial coronation took place in the Lateran Basilica on 4 June 1133. Emperor Lothair continued to avoid explicit resistance against papal impediments on his royal office. He ignored Innocent's bull, in which he advocated imperial authority derived from him and Lothair recognized papal claims to the vast Matildine estates in Northern Italy (formerly owned by Countess Matilda of Tuscany), although he was able to secure the territorial fiefs.
