Catholic priests were executed in concentration camps alongside Jews; for example, 2,600 Catholic priests were imprisoned in Dachau, and 2,000 of them were executed (cf. "Priesterblock"). A further 2,700 Polish priests were executed (a quarter of all Polish priests), and 5,350 Polish nuns were either displaced, imprisoned, or executed. Many Catholic laymen and clergy played notable roles in sheltering Jews during the Holocaust, including Pope Pius XII. The head rabbi of Rome became a Catholic in 1945 and, in honour of the actions the pope undertook to save Jewish lives, he took the name Eugenio (the pope's first name). A former Israeli consul in Italy claimed: "The Catholic Church saved more Jewish lives during the war than all the other churches, religious institutions, and rescue organisations put together."
