Pope Paul IV, C.R. (Latin: Paulus IV; 28 June 1476 – 18 August 1559), born Gian Pietro Carafa, was head of the Catholic Church and ruler of the Papal States from 23 May 1555 to his death in 1559. While serving as papal nuncio in Spain, he developed an anti-Spanish outlook that later coloured his papacy.
Lando (also known as Landus) was the pope from c. September 913 to his death c. March 914. His short pontificate fell during an obscure period in papal and Roman history, the so-called Saeculum obscurum (904–964).
