Inter caetera divinai and Inter caetera I – establishes rights of discovery and conversion of non-Christians by Christian nations.

Inter caetera II – draws line of demarcation between Spanish and Portuguese "possessions" in New World. Combines and slightly expands content of the first two:

[O]ur beloved son, Christopher Columbus . . . 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, after earnest consideration of all matters, especially of the rise and spread of the Catholic faith, as was the fashion of your ancestors, kings of renowned memory, you have purposed with the favor of divine clemency to bring under your sway the said mainlands and islands with their residents and inhabitants and to bring them to the Catholic faith. Hence, heartily commending in the Lord this your holy and praiseworthy purpose, and desirous that it be duly accomplished, and that the name of our Savior be carried into those regions, we exhort you very earnestly in the Lord and by your reception of holy baptism, whereby you are bound to our apostolic commands, and by the bowels of the mercy of our Lord Jesus Christ, enjoin strictly, that inasmuch as with eager zeal for the true faith you design to equip and despatch this expedition, you purpose also, as is your duty, to lead the peoples dwelling in those islands and countries to embrace the Christian religion. . . .

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 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 south, by drawing and establishing a line from the Arctic pole, namely the north, to the Antarctic pole, namely the south.
