Simón Bolívar became president of Gran Colombia in 1819 after the region gained independence from Spain. He led a military-controlled state. Citizens did not like the government's position under Bolívar: The people in the military were unhappy with their roles, and the civilians were of the opinion that the military had too much power. After the dissolution of Gran Colombia, New Grenada continued to have conflicts between conservatives and liberals. These conflicts were each concentrated in particular regions, with conservatives particularly in the southern mountains and the Valley of Cauca. In the mid-1840s some leaders in Caracas organized a liberal opposition. Antonio Leocadio Guzman was an active participant and journalist in this movement and gained much popularity among the people of Caracas.
