# bio (long form, separated for readability)
bio: |
  Sergius IV became bishop of Rome on 31 July 1009, but his reign was one of the papacy's quieter humiliations: the patrician John Crescentius held the real temporal power, leaving Sergius a figurehead in his own city. Historians still debate whether he issued a summons to expel Muslims from the Holy Land—if genuine, it would predate the crusading movement by generations, though it clearly went nowhere. He died on 12 May 1012. What stuck wasn't his political impotence or his disputed letter, but the precedent: from his time forward, it became tradition for a newly elected pope to take a new name upon assuming the office.
