Editing Pope Gregory XII (section)

==Historiography==
The ''[[Annuario Pontificio]]'' has historically recognized the decisions of the [[Council of Pisa]] (1409). Until the mid-20th century, the ''Annuario Pontificio'' listed Gregory XII's reign as 1406–1409, followed by [[Antipope Alexander V|Alexander V]] (1409–1410) and [[Antipope John XXIII|John XXIII]] (1410–1415).<ref>{{cite book |title=Annuario pontificio per l'anno 1942 |date=1942 |location=Rome |page=21 |quote=205.

Alexander V and the first John XXIII are now considered to be antipopes.
