Treaty of Tordesillas
Treaty between Spain and Portugal concluded at Tordesillas; June 7, 1494
Ratification by Spain, July 2, 1494.
Ratification by Portugal, September 5, 1494.

Background:
The Treaty of Tordesillas was agreed upon by the Spanish and the Portuguese to clear up confusion on newly claimed land in the New World. The early 1400's brought about great advances in European exploration. In order make trade more efficient, Portugal attempted to find a direct water route to the India and China. By using a direct water route, Arab merchants, who owned land trade routes, were not able to make a profit off of the European trade merchants. After Columbus discovered the New World in 1492, it was clear that conflict would soon arise over land claims by Spain and Portugal. The Portuguese also wanted to protect their monopoly on the trade route to Africa and felt it too threatened. It was only after the realization that Columbus had found something big that land became the important issue. The newly discovered land held great potential wealth which would benefit European nations.

On May 4, 1493 Pope Alexander VI took action to clear up any confusion that may have arisen over territorial claims. He issued a decree which established an imaginary line running north and south through the mid-Atlantic, 100 leagues (480 km) from the Cape Verde islands. Spain would have possession of any unclaimed territories to the west of the line and Portugal would have possession of any unclaimed territory to the east of the line.

After further exploration, the Portuguese grew dissatisfied with the agreement when they realized how much more land Spain had been given. In June of 1494 the line was re-negotiated and the agreement was officially ratified during a meeting in the Spanish town of Tordesillas. The Treaty of Tordesillas re-established the line 370 leagues (1,770 km) west of the Cape Verde Islands.

It was evident that there little exploration had taken place at the time the treaty was signed because Spain was granted a much larger portion of land. Portugal was only given possession of Brazil. Portugal pushed over the next several hundred years to moved the border of Brazil westward. Because the line was not very well defined, the Spanish did not put up any opposition to this Portuguese expansion.

In the name of God Almighty, Father, Son, and Holy Ghost, three truly separate and distinct persons and only one divine essence. Be it manifest and known to all who shall see this public instrument, that at the village of Tordesillas, on the seventh day of the month of June, in the year of the nativity of our Lord Jesus Christ 1494, in the presence of us, the secretaries, clerks, and notaries public subscribed below, there being present the honorable Don Enrique Enriques, chief steward of the very exalted and very mighty princes, the lord and lady Don Ferdinand and Dona Isabella, by the grace of God king and queen of Castile, Leon, Aragon, Sicily, Granada, etc., Don Gutierre de Cardenas, chief auditor of the said lords, the king and queen, and Doctor Rodrigo Maldonado, all members of the council of the said lords, the king and queen of Castile, Leon, Aragon, Sicily, Granada, etc., their qualified representatives of the one part, and the honorable Ruy de Sousa, lord of Sagres and Berenguel, Dom Juan de Sousa, his son, chief inspector of weights and measures of the very exalted and very excellent lord Dom John, by the grace of God king of Portugal and of the Algarves on this side and beyond the sea in Africa, lord of Guinea, and Ayres de Almada, magistrate of civil cases in his court and member of his desembargo, all of the council of the said lord King of Portugal, and his qualified ambassadors and representatives, as was proved by both the said parties by means of the letters of authorization and procurations from the said lords their constituents, the tenor of which, word for word, is as follows:

[Here follow the full powers granted by Ferdinand and Isabella to Don Enrique Enriques, Don Gutierre de Cardenas, and Dr. Rodrigo Maldonado on June 5, 1494; and the full powers granted by John II. to Ruy de Sousa, Joao de Sousa, and Ayres Almada on March 8, 1494.]

"Thereupon it was declared by the above-mentioned representatives of the aforesaid King and Queen of Castile, Leon, Aragon, Sicily, Granada, etc., and of the aforesaid King of Portugal and the Algarves, etc.:
[I.] That, whereas a certain controversy exists between the said lords, their constituents, as to what lands, of all those discovered in the ocean sea up to the present day, the date of this treaty, pertain to each one of the said parts respectively; therefore, for the sake of peace and concord, and for the preservation of the relationship and love of the said King of Portugal for the said King and Queen of Castile, Aragon, etc., it being the pleasure of their Highnesses, they, their said representatives, acting in their name and by virtue of their powers herein described, covenanted and agreed that a boundary or straight line be determined and drawn north and south, from pole to pole, on the said ocean sea, from the Arctic to the Antarctic pole. This boundary or line shall be drawn straight, as aforesaid, at a distance of three hundred and seventy leagues west of the Cape Verde Islands, being calculated by degrees, or by any other manner as may be considered the best and readiest, provided the distance shall be no greater than abovesaid. And all lands, both islands and mainlands, found and discovered already, or to be found and discovered hereafter, by the said King of Portugal and by his vessels on this side of the said line and bound determined as above, toward the east, in either north or south latitude, on the eastern side of the said bound provided the said bound is not crossed, shall belong to, and remain in the possession of, and pertain forever to, the said King of Portugal and his successors. And all other lands, both islands and mainlands, found or to be found hereafter, discovered or to be discovered hereafter, which have been discovered or shall be discovered by the said King and Queen of Castile, Aragon, etc., and by their vessels, on the western side of the said bound, determined as above, after having passed the said bound toward the west, in either its north or south latitude, shall belong to, and remain in the possession of, and pertain forever to, the said King and Queen of Castile, Leon, etc., and to their successors.

[2.] Item, the said representatives promise and affirm by virtue of the powers aforesaid, that from this date no ships shall be despatched-namely as follows: the said King and Queen of Castile, Leon, Aragon, etc., for this part of the bound, and its eastern side, on this side the said bound, which pertains to the said King of Portugal and the Algarves, etc.; nor the said King of Portugal to the other part of the said bound which pertains to the said King and Queen of Castile, Aragon, etc.-for the purpose of discovering and seeking any mainlands or islands, or for the purpose of trade, barter, or conquest of any kind. But should it come to pass that the said ships of the said King and Queen of Castile, Leon, Aragon, etc., on sailing thus on this side of the said bound, should discover any mainlands or islands in the region pertaining, as abovesaid, to the said King of Portugal, such mainlands or islands shall pertain to and belong forever to the said King of Portugal and his heirs, and their Highnesses shall order them to be surrendered to him immediately. And if the said ships of the said King of Portugal discover any islands and mainlands in the regions of the said King and Queen of Castile, Leon, Aragon, etc., all such lands shall belong to and remain forever in the possession of the said King and Queen of Castile, Leon, Aragon, etc., and their heirs, and the said King of Portugal shall cause such lands to be surrendered immediately.

[3.] Item, in order that the said line or bound of the said division may be made straight and as nearly as possible the said distance of three hundred and seventy leagues west of the Cape Verde Islands, as hereinbefore stated, the said representatives of both the said parties agree and assent that within the ten months immediately following the date of this treaty their said constituent lords shall despatch two or four caravels, namely, one or two by each one of them, a greater or less number, as they may mutually consider necessary. These vessels shall meet at the Grand Canary Island during this time, and each one of the said parties shall send certain persons in them, to wit, pilots, astrologers, sailors, and any others they may deem desirable. But there must be as many on one side as on the other, and certain of the said pilots, astrologers, sailors, and others of those sent by the said King and Queen of Castile, Aragon, etc., and who are experienced, shall embark in the ships of the said King of Portugal and the Algarves; in like manner certain of the said persons sent by the said King of Portugal shall embark in the ship or ships of the said King and Queen of Castile, Aragon, etc.; a like number in each case, so that they may jointly study and examine to better advantage the sea, courses, winds, and the degrees of the sun or of north latitude, and lay out the leagues aforesaid, in order that, in determining the line and boundary, all sent and empowered by both the said parties in the said vessels, shall jointly concur. These said vessels shall continue their course together to the said Cape Verde Islands, from whence they shall lay a direct course to the west, to the distance of the said three hundred and seventy degrees, measured as the said persons shall agree, and measured without prejudice to the said parties. When this point is reached, such point will constitute the place and mark for measuring degrees of the sun or of north latitude either by daily runs measured in leagues, or in any other manner that shall mutually be deemed better. This said line shall be drawn north and south as aforesaid, from the said Arctic pole to the said Antarctic pole. And when this line has been determined as abovesaid, those sent by each of the aforesaid parties, to whom each one of the said parties must delegate his own authority and power, to determine the said mark and bound, shall draw up a writing concerning it and affix thereto their signatures. And when determined by the mutual consent of all of them, this line shall be considered as a perpetual mark and bound, in such wise that the said parties, or either of them, or their future successors, shall be unable to deny it, or erase or remove it, at any time or in any manner whatsoever. And should, perchance, the said line and bound from pole to pole, as aforesaid, intersect any island or mainland, at the first point of such intersection of such island or mainland by the said line, some kind of mark or tower shall be erected, and a succession of similar marks shall be erected in a straight line from such mark or tower, in a line identical with the above-mentioned bound. These marks shall separate those portions of such land belonging to each one of the said parties; and the subjects of the said parties shall not dare, on either side, to enter the territory of the other, by crossing the said mark or bound in such island or mainland.

[4.] Item, inasmuch as the said ships of the said King and Queen of Castile, Leon, Aragon, etc., sailing as before declared, from their kingdoms and seigniories to their said possessions on the other side of the said line, must cross the seas on this side of the line, pertaining to the said King of Portugal, it is therefore concerted and agreed that the said ships of the said King and Queen of Castile, Leon, Aragon, etc., shall, at any time and without any hindrance, sail in either direction, freely, securely, and peacefully, over the said seas of the said King of Portugal, and within the said line. And whenever their Highnesses and their successors wish to do so, and deem it expedient, their said ships may take their courses and routes direct from their kingdoms to any region within their line and bound to which they desire to despatch expeditions of discovery, conquest, and trade. They shall take their courses direct to the desired region and for any purpose desired therein, and shall not leave their course, unless compelled to do so by contrary weather. They shall do this provided that, before crossing the said line, they shall not seize or take possession of anything discovered in his said region by the said King of Portugal; and should their said ships find anything before crossing the said line, as aforesaid, it shall belong to the said King of Portugal, and their Highnesses shall order it surrendered immediately. And since it is possible that the ships and subjects of the said King and Queen of Castile, Leon, etc., or those acting in their name, may discover before the twentieth day of this present month of June, following the date of this treaty, some islands and mainlands within the said line, drawn straight from pole to pole, that is to say, inside the said three hundred and seventy leagues west of the Cape Verde Islands, as aforesaid, it is hereby agreed and determined, in order to remove all doubt, that all such islands and mainlands found and discovered in any manner whatsoever up to the said twentieth day of this said month of June, although found by ships and subjects of the said King and Queen of Castile, Aragon, etc., shall pertain to and remain forever in the possession of the said King of Portugal and the Algarves, and of his successors and kingdoms, provided that they lie within the first two hundred and fifty leagues of the said three hundred and seventy leagues reckoned west of the Cape Verde Islands to the above-mentioned line-in whatsoever part, even to the said poles, of the said two hundred and fifty leagues they may be found, determining a boundary or straight line from pole to pole, where the said two hundred and fifty leagues end. Likewise all the islands and mainlands found and discovered up to the said twentieth day of this present month of June by the ships and subjects of the said King and Queen of Castile, Aragon, etc., or in any other manner, within the other one hundred and twenty leagues that still remain of the said three hundred and seventy leagues where the said bound that is to be drawn from pole to pole, as aforesaid, must be determined, and in whatever part of the said one hundred and twenty leagues, even to the said poles,-they that are found up to the said day shall pertain to and remain forever in the possession of the said King and Queen of Castile, Aragon, etc., and of their successors and kingdoms; just as whatever is or shall be found on the other side of the said three hundred and seventy leagues pertaining to their Highnesses, as aforesaid, is and must be theirs, although the said one hundred and twenty leagues are within the said bound of the said three hundred and seventy leagues pertaining to the said King of Portugal, the Algarves, etc., as aforesaid.

And if, up to the said twentieth day of this said month of June, no lands are discovered by the said ships of their Highnesses within the said one hundred and twenty leagues, and are discovered after the expiration of that time, then they shall pertain to the said King of Portugal as is set forth in the above.

The said Don Enrique Enriques, chief steward, Don Gutierre de Cardenas, chief auditor, and Doctor Rodrigo Maldonado, representatives of the said very exalted and very mighty princes, the lord and lady, the king and queen of Castile, Leon, Aragon, Sicily, Granada, etc., by virtue of their said power, which is incorporated above, and the said Ruy de Sousa, Dom Joao de Sousa, his son, and Arias de Almadana, representatives and ambassadors of the said very exalted and very excellent prince, the lord king of Portugal and of the Algarves on this side and beyond the sea in Africa, lord of Guinea, by virtue of their said power, which is incorporated above, promised, and affirmed, in the name of their said constituents, [saying that they and their successors and kingdoms and lordships, forever and ever, would keep, observe, and fulfill, really and effectively, renouncing all fraud, evasion, deceit, falsehood, and pretense, everything set forth in this treaty, and each part and parcel of it; and they desired and authorized that everything set forth in this said agreement and every part and parcel of it be observed, fulfilled, and performed as everything which is set forth in the treaty of peace concluded and ratified between the said lord and lady, the king and queen of Castile, Aragon, etc., and the lord Dom Alfonso, king of Portugal (may he rest in glory) and the said king, the present ruler of Portugal, his son, then prince in the former year of 1479, must be observed, fulfilled, and performed, and under those same penalties, bonds, securities, and obligations, in accordance with and in the manner set forth in the said treaty of peace. Also they bound themselves [by the promise]that neither the said parties nor any of them nor their successors forever should violate or oppose that which is abovesaid and specified, nor any part or parcel of it, directly or indirectly, or in any other manner at any time, or in any manner whatsoever, premeditated or not premeditated, or that may or can be, under the penalties set forth in the said agreement of the said peace; and whether the fine be paid or not paid, or graciously remitted, that this obligation, agreement, and treaty shall continue in force and remain firm, stable, and valid forever and ever. That thus they will keep, observe, perform, and pay everything, the said representatives, acting in the name of their said constituents, pledged the property, movable and real, patrimonial and fiscal, of each of their respective parties, and of their subjects and vassals, possessed and to be possessed. They renounced all laws and rights of which the said parties or either of them might take advantage to violate or oppose the foregoing or any part of it; and for the greater security and stability of the aforesaid, they swore before God and the Blessed Mary and upon the sign of the Cross, on which they placed their right hands, and upon the words of the Holy Gospels, wheresoever they are written at greatest length, and on the consciences of their said constituents, that they, jointly and severally, will keep, observe, and fulfill all the aforesaid and each part and parcel of it, really and effectively, renouncing all fraud, evasion, deceit, falsehood, and pretense, and that they will not contradict it at any time or in any manner. And under the same oath they swore not to seek absolution or release from it from our most Holy Father or from any other legate or prelate who could give it to them. And even though, proprio motu, it should be given to them, they will not make use of it; rather, by this present agreement, they, acting in the said name, entreat our most Holy Father that his Holiness be pleased to confirm and approve this said agreement, according to what is set forth therein; and that he order his bulls in regard to it to be issued to the parties or to whichever of the parties may solicit them, with the tenor of this agreement incorporated therein, and that he lay his censures upon those who shall violate or oppose it at any time whatsoever. Likewise, the said representatives, acting in the said names, bound themselves under the same penalty and oath, that within the one hundred days next following, reckoned from the day of the date of this agreement, the parties would mutually exchange the approbation and ratification of this said agreement, written on parchment, signed with the names of the said lords, their constituents, and sealed with their hanging leaden seals; and that the instrument which the said lords, the king and queen of Castile, Aragon, etc., should have to issue, must be signed, agreed to, and sanctioned by the very noble and most illustrious lord, Prince Don Juan, their son. Of all the foregoing they authorized two copies, both of the same tenor exactly, which they signed with their names and executed before the undersigned secretaries and notaries public, one for each party. And whichever copy is produced, it shall be as valid as if both the copies which were made and executed in the said town of Tordesillas, on the said day, month, and year aforesaid, should be produced.
