 In a letter of 1 September 1077, Pope Gregory VII wrote to the bishops, clergy, civil leaders, and people of Corsica, acknowledging his responsibility for oversight of their well-being as part of the lands of S. Peter, but admitting that he was unable to do so personally and effectively.He had therefore appointed Bishop-elect Landulfus of Pisa to be his legate in Corsica.On 30 November 1078, Pope Gregory confirmed all the privileges that belonged to the Church of Pisa, as well as the legateship of Corsica.
