The Papal bull Inter Caetera Alexander VI May 4 1493Alexander, bishop, servant of the servants of God, to the illustrious sovereigns, our very dear son in Christ, Ferdinand, king, and our very dear daughter in Christ, Isabella, queen of Castile
. . . . We have indeed learned that you, who for a long time had intended to seek out and discover certain islands and mainlands remote and unknown and not hitherto discovered by others, to the end that you might bring to the worship of our Redeemer and the profession of the Catholic faith their residents and inhabitants, having been up to the present time greatly engaged in the siege and recovery of the kingdom itself of Granada were unable to accomplish this holy and praiseworthy purpose; but the said kingdom having at length been regained, as was pleasing to the Lord, with a wish to fulfill your desire, chose our beloved son, Christopher Columbus . . . whom you furnished with ships and men equipped for like designs, not without the greatest hardships, dangers, and expenses, to make diligent quest for these remote and unknown mainlands and islands through the sea, where hitherto no one had sailed; and they at length with divine aid and with the utmost diligence sailing in the ocean sea, discovered certain very remote islands and even mainlands that hitherto had not been discovered by others; wherein dwell very many peoples living in peace, and, as reported, going unclothed, and not eating flesh. . . . Wherefore, as becomes Catholic kings and princes , . . you have purposed . . . to bring under your sway the said mainlands and islands. . . . And in order that you may enter upon so great an undertaking with greater readiness and heartiness endowed with the benefit of our apostolic favor, we, of our own accord, not at your instance nor the request of anyone else in your regard, but out of our own sole largess and certain knowledge and out of the fullness of our apostolic power, by the authority of Almighty God conferred upon us in blessed Peter and of the vicarship of Jesus Christ, which we hold on earth, do by tenor of these presents, should any of said islands have been found by your envoys and captains, give, grant, and assign to you and your heirs and successors, kings of Castile and Leon, forever, together with all their dominions, cities, camps, places, and villages, and all rights, jurisdictions, and appurtenances, all islands and mainlands found and to be found, discovered and to be discovered towards the west and the south, by drawing and establishing a line from the Arctic pole, namely the north, to the Antarctic pole, namely the south, no matter whether the said mainlands and islands are found and to be found in the direction of India or towards any other quarter, the said line to be distant one hundred leagues towards the west and south from any of the islands commonly known as the Azores and Cape Verde. With this proviso, however, that none of the islands and mainlands, found and to be found, discovered and to be discovered, beyond that said line towards the west and south, be in the actual possession of any Christian king or prince up to the birthday of our Lord Jesus Christ just past from which the present year 1493 begins. . . . Furthermore, under penalty of excommunication late sententie to be incurred ipso facto, should anyone thus contravene, we strictly forbid all persons of whatsoever rank, even imperial and royal, or of whatsoever estate, degree, order, or condition, to dare without your special permit or that of your aforesaid heirs and successors, to go for the purpose of trade or any other reason to the islands or mainlands . . . apostolic constitutions and ordinances and other decrees whatsoever to the contrary notwithstanding. . . . Let no one therefore, infringe, or with rash boldness contravene, this our recommendation, exhortation, requisition, gift, grant, assignment, constitution, deputation, decree, mandate, prohibition, and will. Should anyone presume to attempt this, be it known to him that he will incur the wrath of Almighty God and of the blessed apostles Peter and Paul.
Given at Rome, at St. Peter's,
in the year of the incarnation of our Lord 1493,
the fourth of May,
