In July 983, Pope Benedict VII, a longtime Ottonian supporter, died of natural causes after having reigned for almost ten years. Otto II returned to Rome in September to name a new Pope, selecting the Bishop of Pavia Pietro Canepanova (who reigned as Pope John XIV) in November or early December. While Otto II was in Rome, a malaria outbreak in central Italy prevented the resumption of military activity in southern Italy. The outbreak ultimately led to the death of the Emperor himself in his palace at Rome on December 7, 983, at the age of 28, after having reigned for just over a decade. Otto II's money and possessions were divided among the Catholic Church, the poor of the Empire, his mother Adelaide and sister Matilda, and those nobles loyal to him. Otto II was then buried in the atrium of St. Peter's Basilica.
