Creator Omnium
Creator Omnium was a papal bull issued by Pope Eugene IV on 17 December 1434 that condemned the enslavement of the inhabitants of the Canary Islands and ordered, under pain of excommunication, that all such slaves be set free within 15 days of its publication.
The bull is also known as Sicut Dudum with the date of 13 January 1435, a title that is the incipit of the third paragraph of Creator Omnium, echoing the abbreviated version reported by Cardinal Cesare Baronius in his Annales Ecclesiastici.
