  The "constitution" of the Empire still remained largely unsettled at the beginning of the 15th century. Feuds often happened between local rulers. The " robber baron " (Raubritter) became a social factor.
  
  Simultaneously, the Catholic Church experienced crises of its own, with wide-reaching effects in the Empire. The conflict between several papal claimants (two anti-popes and the "legitimate" Pope) ended only with the Council of Constance (1414–1418); after 1419 the Papacy directed much of its energy to suppressing the Hussites. The medieval idea of unifying all Christendom into a single political entity, with the Church and the Empire as its leading institutions, began to decline.
  
  With these drastic changes, much discussion emerged in the 15th century about the Empire itself. Rules from the past no longer adequately described the structure of the time, and a reinforcement of earlier Landfrieden was urgently needed.
  
  The vision for a simultaneous reform of the Empire and the Church on a central level began with Sigismund (reigned 1433–1437, King of the Romans since 1411), who, according to historian Thomas Brady Jr., "possessed a breadth of vision and a sense of grandeur unseen in a German monarch since the thirteenth century". But external difficulties, self-inflicted mistakes and the extinction of the Luxembourg male line made this vision unfulfilled.
  
  Frederick III was the first Habsburg to be crowned Holy Roman Emperor, in 1452. He had been very careful regarding the reform movement in the empire. For most of his reign, he considered reform as a threat to his imperial prerogatives. He avoided direct confrontations, which might lead to humiliation if the princes refused to give way. After 1440, the reform of the Empire and Church was sustained and led by local and regional powers, particularly the territorial princes. In his last years, he felt more pressure on taking action from a higher level. Berthold von Henneberg, the Archbishop of Mainz, who spoke on behalf of reform-minded princes (who wanted to reform the Empire without strengthening the imperial hand), capitalized on Frederick's desire to secure the imperial election for his son Maximilian. Thus, in his last years, he presided over the initial phase of Imperial Reform, which would mainly unfold under his Maximilian. Maximilian himself was more open to reform, although naturally he also wanted to preserve and enhance imperial prerogatives. After Frederick retired to Linz in 1488, as a compromise, Maximilian acted as mediator between the princes and his father. When he attained sole rule after Frederick's death, he would continue this policy of brokerage, acting as the impartial judge between options suggested by the princes.
