was generally met with indifference or outright hostility among other sectors of society and, most importantly for future political developments, by Vice-President Santander himself. In November two assemblies met in Venezuela to discuss the future of the region, but no formal independence was declared at either. That same month, skirmishes broke out between the supporters of Páez and Bolívar in the east and south of Venezuela. By the end of the year, Bolívar was in Maracaibo preparing to march into Venezuela with an army, if necessary. Ultimately, political compromises prevented this. In January, Bolívar offered the rebellious Venezuelans a general amnesty and the promise to convene a new constituent assembly before the ten-year period established by the Constitution of Cúcuta, and Páez backed down and recognized Bolívar's authority. The reforms, however, never fully satisfied the different political factions in Gran Colombia, and no permanent consolidation was achieved. The instability of the state's structure was now apparent to all. In 1828, the new constituent assembly, the Convention of Ocaña, began its sessions. At its opening, Bolívar again proposed a new constitution based on the Bolivian one, but this suggestion continued to be unpopular. The convention fell apart when pro-Bolívar delegates walked out rather than sign a federalist constitution. After this failure, Bolívar believed that by centralizing his constitutional powers he could prevent the separatists (the New Granadians represented mainly by Francisco de Paula Santander and José María Obando, and the Venezuelans by José Antonio Páez) from bringing down the union. He ultimately failed to do so. As the collapse of the country became evident in 1830, Bolívar resigned from the presidency. Internal political strife between the different regions intensified even as General Rafael Urdaneta temporarily took power in Bogotá, attempting to use his authority to ostensibly restore order, but actually hoping to convince Bolívar to return to the presidency and the country to accept him. The federation finally dissolved in the closing months of 1830 and was formally abolished in 1831. Venezuela, Ecuador and New Granada came to exist as independent states. War with Peru Aftermath The dissolution of Gran Colombia represented the failure of Bolívar's vision. The former republic was replaced by the republics of Venezuela, Ecuador, and New Granada. The former Department of Cundinamarca (as established in 1819 at the Congress of Angostura) became a new country, the Republic of New Granada. In 1858, New Granada was replaced by
