Dum Diversas

Papal bull concerning imperialism

Dum Diversas is a papal bull issued on 18 June 1452 by Pope Nicholas V. It authorized King Afonso V of Portugal to fight, subjugate, and conquer “those rising against the Catholic faith and struggling to extinguish Christian Religion”— namely, the "Saracens (Muslims) and pagans" in a militarily disputed African territory. The document consigned warring enemies that lost to "perpetual servitude". This and the subsequent bull, issued by Nicholas in 1455, gave the Portuguese what they saw as moral justification to freely acquire slaves along the African coast by force or trade. The edicts are thus seen as having facilitated the Portuguese slave trade from West Africa and as having legitimized the European colonization of the African continent.
