Papal Names

Papal names often include a Roman numeral ordinal, parallel to royal regnal numbers. The numeral counts how many popes have taken that name; it is not a calendar year.

Ordinal reading

After a papal name, a numeral such as XII or XIV means “the twelfth” or “the fourteenth” bearer of that name. Decode the Roman letters to an integer, then express it as an ordinal in speech or prose.

The same decoding skills appear in royal names and the general guide how to read Roman numerals.

What to avoid when interpreting

  • Do not treat the numeral as a year of election or consecration.
  • Do not invent or assume who the current officeholder is from a numeral alone.
  • Do not confuse short ordinals with copyright-style years such as MMXXVI.

Year forms are covered in Roman numeral years.

Notation details

Papal ordinals use the standard seven symbols and normal subtractive pairs when needed (IV, IX, XL, and so on). Copy the letters exactly as written in the source you are reading, then convert with Roman numeral rules.

Related numbered traditions

Other institutions also number officeholders or editions with Roman numerals. For event numbering rather than personal names, see Super Bowl and Olympics topics. For general decoding, use the decoder.
