In addition, there were conflicting interests between the political administration and the military of the new nation, as well as tension between local leaders, who did not accept to be subordinates of the central government.
In 1826 General José Antonio Páez, an important caudillo and military leader of the department of Venezuela, rebelled against the central government in a separatist movement called La Cosiata, which is brought to a temporary but peaceful resolution by the personal intervention of Simón Bolívar in 1827, who promised to convene a constituent congress to rewrite the nation's constitution, despite the fact that Constitution of Cúcuta stated that it could not be reformed before ten years (that is, not until 1831).
On August 27, 1828, Simon Bolivar proclaimed himself dictator and signed an order revoking the powers of the deputies of Bogotá to the convention and declaring its decrees null and void.
On August 27, Bolívar promulgated an organic decree, which he called the "Fundamental Law," through which he assumed the dictatorship and left the Constitution of Cúcuta without effect, dissolving Congress and other political offices, such as the vice-presidency, which might be points of opposition to him.
A few weeks later, there would be an attempt on Bolívar's life, which he survived, but the nation remained unstable until 1831 when separatist movements won out and Gran Colombia was dissolved.
