What was Gran Colombia? What hopes did Simon Bolivar have for this alliance?

Gran Colombia had a brief, vigorous existence during the war. Subsequent civilian and military rivalry for public office and regional jealousies led to a rebellion in Venezuela in 1826. After ruling as dictator from 1828 to 1830, Bolívar convoked a convention to frame a new constitution. It was recognized only in Nueva Granada (Colombia and Panama). Bolívar resigned and left for the northern coast, where he died, near Santa Marta, on December 17, 1830. By that time Venezuela and Ecuador had seceded from Gran Colombia. Thus Gran Colombia essentially passed into history with its principal architect.
