"I repeat that of all I have expressed, there is nothing of so much importance at this moment as the formation of a league truly American. But this confederation must not be formed simply on the principles of an ordinary alliance for attack and for defense; it must be closer than the one lately formed in Europe against the freedom of the people. "It is necessary that our society be a society of sister nations, divided for the time being in the exercise of their sovereignty, on account of the course of human events, but united, strong and powerful, in order to support each other against aggressions of foreign powers. "It is indispensable that you should incessantly urge the necessary to establish immediately the foundations of an amphictyonic body or assembly of plenipotentiaries to promote the common interests of the American states, to settle the differences which may arise in the future between peoples which have the same habits and the same customs, and which, through the lack of such a sacred institution, may perhaps kindle deplorable wars, such as those which have destroyed other regions less fortunate." In the projected treaty carried by the same representative, the following appears: "Both contracting parties guarantee to each other the integrity of their respective territories, as constituted before the present war, keeping the boundaries possessed at that time by each captaincy general or viceroyalty of those who now have resumed the exercise of their sovereignty, unless in a legal way two or more of them have agreed to form a single body or nation, as has happened with the old captaincy general of Venezuela and the kingdom of Nueva Granada, which now form the Republic of Colombia." Similar instructions were given to the representative sent to Mexico. The treaty arranged with Perú was similar to another entered into afterwards with Chile. In both documents it was stipulated: that an assembly should be organized with representatives of the different countries; that all the governments of America, or of that part of America which had belonged to Spain, should be invited to enter into that union, league, or perpetual confederation; that the assembly of plenipotentiaries should be entrusted with the work of laying the foundation for, and of establishing, the closer relations which should exist among all of those states; and that this assembly should "serve them as a council in great conflicts, as a point of contact in the common dangers, as faithful interpreter of their public treaties when difficulties occur, and as an arbitral judge and conciliator in their disputes and differences." In this way, two great principles were sanctioned by Bolívar: the principle of _uti-possidetis_ and the principle of arbitration, which was proclaimed in America, for the first time, by Bolívar as president of Colombia.
