And that being authorized by the privilege of the Apostolic grace, you may the more freely and boldly take upon you the enterprise of so great a matter, we of our own motion, and not either at your request nor at the instant petition of any other person, but of our own mere liberality and certain science, and by the fulness of Apostolic power, do give, grant, and assign to you, your heirs and successors, all the firm lands and islands found or to be found, discovered or to be discovered toward the west and south, drawing a line from the pole Arctic to the pole Antarctic (that is) from the north to the south:  containing in this donation, whatsoever firm lands or islands are found or to be found toward India or toward any other part whatsoever it be, being distant from, or without the aforesaid line drawn a hundred leagues toward the west and south from any of the islands which are commonly called De Los Azores and Cabo Verde.  All the islands, therefore, and firm lands, found and to be found, discovered and to be discovered, from the said line toward the west and south, such as have not actually been heretofore possest by any other Christian king or prince until the day of the nativity of our Lord Jesus Christ last passed, from the which beginneth this present year.

We, by the authority of almighty God granted unto us in Saint Peter, and by the office which we bear on the earth in the stead of Jesus Christ, do forever, by the tenure of these presents, give, grant, assign, unto you, your heirs, and successors (the kings of Castile and Leon), all those lands and islands, with their dominions, territories, cities, castles, towers, places, and villages, with all the right and jurisdictions thereunto pertaining:  constituting, assigning, and deputing, you, your heirs, and successors the lords thereof, with full and free power, authority, and jurisdiction.  Decreeing nevertheless by this, our donation, grant, and assignation, that from no Christian Prince which actually hath possest the aforesaid islands and firm lands unto the day of the nativity of our Lord beforesaid, their right obtained to be understood hereby to be taken away, or that it ought to be taken away.

Furthermore, we command you in the virtue of holy obedience (as you have promised, and we doubt not you will do upon mere devotion and princely magnanimity), to send to the said firm lands and islands honest, virtuous, and learned men, such as fear God, and are able to instruct the inhabitants in the Catholic faith and good manners, applying all their possible diligence in the premises.
