The fundamental creation of the Congress was the Constitution of Cúcuta.
Cúcuta was the birthplace of Simón Bolívar's dream of uniting South America in one single federal state, and of the principles upon which the political institutions of South America would replace those inherited from the 300 years of Spanish colonial history.
Prior to 1819, Simón Bolívar, as well as others who facilitated the revolutionary establishment of the Venezuelan Republic, referred to all of South America as Colombia. Since then, Bolívar had proposed the union of what is today Venezuela, Colombia and Ecuador in a nation by the same name. Since Bolívar based the borders of the proposed nation on the principle of uti possidetis, Panama and Ecuador were included, despite having no representation at this Congress or the one in Angostura, since they had been part of the old Viceroyalty of New Granada. At the Congress of Angostura in 1819 the word "Colombia" was, therefore, used to describe this new country, when it was proposed. The cities of Bogotá, Caracas, and Quito were designated regional capitals within the new nation. Most of the territory of Gran Colombia, with the exceptions of southern Colombia and Ecuador, was largely independent from Spain at the time the Congress of Cúcuta began holding sessions.
Places that were related to the Congress of Cúcuta, together with the House of Santander (Casa de Santander), are now protected due to historic significance, and form part of the Park of the Great Colombia.
The culminating event of the Congress of Cúcuta took place on August 30, 1821, in the city of Cúcuta. A constitution had been written which established the law of the Republic of Colombia (Gran Colombia), and determined the country's capital and political boundaries. The convention, organized by Antonio Nariño and led by Simón Bolívar.
At 11 o'clock on the morning of October 3, 1821 Simón Bolívar entered the debating chamber of the Congress of Cúcuta, located at the time in the sacristy of the parish church of the town of Villa del Rosario de Cúcuta (the old name for the town). He was accompanied by a commission of deputies and the members of the joint chiefs of staff of his armed forces. He sat beside the speaker of the assembly and, whilst the entire assembly stood, was sworn in as the President of the nascent Republic of Gran Colombia, composed of Venezuela and Cundinarmaca, the republican name by which New Granada was by then known. After a speech, and the naming of Santander as Vice-President, the text of the Constitution of the new republic was read out.
The oath I have just taken in my capacity as President of Colombia represents for me an act of conscience, which further places me under the obligation to submit to the laws of my country. Only a profound sense of respect for the will of the people could compel me to submit to the onerous position of Supreme Magistrate. The gratitude for so doing which I feel emanates from the representatives of the people, moreover, imposes upon me the pleasant duty, to continue in the service of my country, to defend, with my possessions, my blood and my honour, this Constitution, which cements the Rights of Man, joining them in the cause of freedom, the public good, and glory. The Constitution of Colombia, together with her independence, will constitute the Holy Altar on which I shall make the necessary sacrifices. For her I will march to the very edge of Colombia to break the chains which bind the sons of Ecuador, and, making them free, invite them to join her.
Sir, I hope that you will authorize me to join together, in beneficence, those peoples which nature and Heaven have made our brothers. Once this work, born of our wisdom and my zeal, is done, nothing will remain for us to achieve but peace, so that we may give to Colombia its rest and its glory. Therefore, Sir, I preach you ardently, do not show yourself deaf to the call of my conscience and my honour, which bid me loudly to remain solely a citizen. I feel the necessity of quitting the Presidency of the Republic, which the people hold as the Master of their Hearts. I am the son of war; a man brought to power only by dint of combat; fortune has kept for me this rank and victory has confirmed me in it. But these are not the titles consecrated by justice, good fortune, and the will of the people. The sword which has governed Colombia is not the scales of justice, but the whip of misfortune which, sometimes, Heaven lets fall to Earth to punish tyrants and boastful nations. That sword serves no purpose when there is peace, and this should be the last time I am permitted to wield it; so I have sworn to myself, because I have promised it to Colombia, and because there can be no Republic where the people cannot wield power. A man such as myself, is a dangerous thing in a popular government; my existence is a clear and present danger to the sovereignty of the nation. I would wish to be a citizen, a free man, so that all may be free men. I prefer the name of Citizen to that of Liberator, for the latter being born of war, the former is born of law. I beseech thee, Sir, I should give up all my titles, if in exchange I could procure but one: that of The Good Citizen.
