The Congress of Angostura was convened by Simón Bolívar and took place in Angostura (today Ciudad Bolívar) during the wars of independence of Colombia and Venezuela, culminating in the proclamation of the Republic of Colombia (historiographically called Gran Colombia). It met from February 15, 1819, established the new independent-from-Spain nation on December 17, was interrupted by further independentist activity, and reconvened on July 31, 1821, when the Congress of Cúcuta began its sessions. The Angostura assembly consisted of twenty-six delegates representing Venezuela and New Granada (today Colombia).
Important parts of the countries were still under Spanish rule, so elections only took place in the areas of southern Venezuela and Margarita Island controlled by the patriot forces. The delegates from New Granada were chosen from among the exiles fighting alongside the Venezuelan patriots. At its first meeting on February 19, 1819, Bolivar gave his famous Address at Angostura, but not all of the proposals contained in it were accepted (most notably the suggestions of a highly exalted ceremonial president-for-life who would govern through powerful ministers accountable to parliament and a hereditary senate, both modeled on the British example, and a "fourth" branch of government, the "moral" one, loosely modeled on the Classical Areopagus).
The Congress of Angostura is considered Venezuela's second legislative congress, the first being the one that met in 1811. Its culminating piece of legislation was the Venezuelan Constitution of 1819, officially adopted on August 15, but quickly made obsolete by the creation of the Republic of Colombia on December 17, 1819. This new nation comprised Venezuela, New Granada (today Colombia and Panamá) and Quito (today Ecuador). In order to differentiate it from the present Republic of Colombia, historians have traditionally called the nation Gran Colombia. A constitution for the new nation was created at the Congress of Cúcuta in August 1821.
The congress established three large departments for the new country: Venezuela (corresponding to the modern country of Venezuela), Cundinamarca (what today is Colombia, Panama and some parts of Central America) and Quito (today Ecuador). Simon Bolívar was elected president, Francisco Antonio Zea vice president, Juan Germán Roscio vice president of Venezuela and Francisco de Paula Santander vice president of Cundinamarca.
On December 17, 1819, the Fundamental Law of the Republic of Colombia (Ley Fundamental de Colombia,[1] in Spanish) was enacted by the congressmen in the city of Angostura (nowadays Ciudad Bolívar). It consisted of fourteen articles in which the Republic of Gran Colombia established its political structure, in consideration of the fact that "the provinces of Venezuela and New Grenada (sic)" are "united in a single republic" that could not stand if divided in two different nations, even if they are "united by the closest ties". Therefore, the birth of Gran Colombia would be created "by necessity and mutual interest".
Basically, the document explained how Colombia was going to be as an independent nation, in relation to the reasons that motivated the political union of Venezuela and New Granada. The Fundamental Law of the Republic of Colombia was thus as follows:
At the end of the Fundamental Law appeared the signatures of Francisco Antonio Zea, who was the president of the congress, and Diego de Vallenilla, a deputy and secretary. Other politicians who signed the document were: Juan Germán Roscio, Manuel Cedeño, Juan Martínez, José María Vergara y Lozano, José España, Luis Tomás Peraza, Antonio M. Briceño, Eusebio Afanador, Francisco Conde, Diego Bautista Urbaneja, Juan Vicente Cardozo, Ignacio Muñoz, Onofre Basalo, Domingo Alzuru, José Tomás Machado and Ramón García Cádiz.
Finally, Simón Bolívar approved the printing, publication and implementation of the Fundamental Law, with the stamp of the State.
