Not to mention in same said document

In 1493 Pope Alexander VI issued the Bull Inter caetera stating one Christian nation did not have the right to establish dominion over lands previously dominated by another Christian nation. Together, the Dum Diversas, the Romanus Pontifex and the Inter Caetera have been interpreted as serving as a justification for the Age of Imperialism. They were also early influences on the development of the slave trade of the 15th and 16th centuries, even though the papal bull Sublimus Dei of 1537 forbade the enslavement of non-Christians. The executive brief for Sublimus Dei was withdrawn by the Pope after protests by the Spanish monarchy. Paul III publicly sanctioned slavery in Rome in 1545, the enslavement of Henry VIII in 1547 and the purchase of Muslim slaves in 1548.[11]

Norman Housley observes that "it would be unfair to criticize the papal court exclusively for its failure to be more discriminating in its grants or to take more frequently the kind of action which Eugenius IV adopted in 1454 over the Canaries".[12] The idea of discovery, and the conversion and enslavement that accompanied it, were identified with hard-held concepts of crusade and chivalry at that time.
