In page Pope Pius XII:

"

According to rumor, he asked for another ballot to be taken to ensure the validity of his election.[citation needed] After his election was indeed confirmed, he chose the name Pius XII in honor of his immediate predecessor. He was quoted as saying "I call myself Pius; my whole life was under Popes with this name, but especially as a sign of gratitude towards Pius XI."[5] In December 1937, during his last consistory, Pius XI had strongly hinted to the cardinals that he expected Pacelli to be his successor, saying "He is in your midst."[6][7]
