(d. 1159, born Nicholas Breakspear, the only Englishman to occupy the papal throne) did not use a personal coat of arms; Nevertheless, he was given attributed arms (showing a broken spear) in this 17th-century portrait.
Heraldry developed out of military insignia from the time of the
First Crusade. The first papal coats of arms appeared when heraldry began to be codified in the 12th to 13th centuries. At first, the popes simply used the secular coat of arms of their family. Thus,
Innocent IV (1243–1254), who was born Sinibaldo Fieschi, presumably used the Fieschi coat of arms, as did
Adrian V (Ottobuono Fieschi), the nephew of Innocent IV. According to Michel Pastoureau,
Innocent IV (1243–1254) is likely the first who displayed personal arms, but the first of whom a contemporary coat of arms survives is
Boniface VIII (1294–1303). Modern sources show
attributed arms of the popes of the second half of the 12th century; thus, editions of the
Annuario Pontificio of the 1960s presented the arms of the popes beginning with
Innocent III (1198–1216), and John Woodward gave those of the popes from
Lucius II (1144–1145) onward, though he noted that "it seems probably that many of the early popes made little if any use of their family arms". Thus, Innocent III (Lotario di Segni, 1160–1216) and Gregory IX (Ugolino di Segni, 1145–1241) may have used the coat of arms of the counts of
Segni. The following papal coat of arms should be considered
traditional, lacking contemporary attribution. For the popes of noble families, the coats of arms of the family is substituted, and for commoners, the traditional coat of arms as shown in early modern heraldic sources. ==Late Middle Ages and Renaissance==
