Fighting between Gran Colombia and Peru over disputed borders strained Gran Colombia’s finances and politics. The war ended with the Treaty of Guayaquil, but internal disagreements over central authority versus regional autonomy continued to sharpen. These pressures set the stage for resignations and legal breakups soon after.
In January 1830, Simón Bolívar presented his resignation during a constitutional convention convened to address the republic’s political breakdown. His departure signaled that the union’s founding leader could no longer hold the regions together. This opened the way for a new, less-stable national leadership and accelerated secession plans.
Gran Colombia held indirect presidential elections to replace Bolívar, and Joaquín Mosquera was elected president. Domingo Caycedo was elected vice president, reflecting a hurried attempt to restore constitutional order. The new leadership, however, had little leverage over regions already moving toward independence.
Venezuelan leaders assembled a constituent congress in Valencia to organize a separate national government. This move formalized Venezuela’s break with the Gran Colombia framework and shifted power toward regional institutions. The congress became the venue for adopting a new Venezuelan constitution later in 1830.
In Quito, local leaders declared the former Southern District’s separation from Gran Colombia, launching what became Ecuador. The declaration reflected both regional political identity and the practical collapse of central control from Bogotá. It also created urgency to convene a constituent assembly to give the new state a legal foundation.
Juan José Flores, acting as the southern region’s top civil and military authority, issued a decree calling for a constituent assembly. The goal was to draft a constitution and stabilize the new government after separation. This step moved Ecuador’s break from a political decision into a constitutional process.
In early September 1830, the central government in Bogotá was pushed aside under military pressure. This upheaval further weakened any remaining claim that Gran Colombia functioned as a unified constitutional state. The power vacuum made negotiated legal dissolution more likely than reunification.
General Rafael Urdaneta took control as acting president after the coup, claiming to preserve order and the union. Instead, the takeover triggered more conflict and made compromise with regional governments harder. His rule became a short-lived last attempt to keep Gran Colombia intact through centralized authority.
Ecuador’s constituent congress adopted a constitution in Riobamba, then it was promulgated later in September. The constitution unified the former southern departments under a new national framework. This made Ecuador’s separation legally durable and reduced Gran Colombia to the central region (and contested areas).
Venezuela approved its new constitution in September 1830, defining the state’s government after secession. By creating a separate constitutional order, Venezuela strengthened the legal reality that Gran Colombia could not be restored as a single republic. The constitution provided institutional permanence to Venezuela’s independence.
After fighting and political deadlock, Urdaneta and constitutional leaders reached the Apulo Agreement (Convenio de Apulo). Urdaneta recognized Domingo Caycedo as acting president, and the agreement aimed to return authority to a constitutional process. This transition cleared the way for a convention to decide the central region’s legal future after the union’s collapse.
Caycedo resumed executive power in early May 1831 and moved to convene representatives of the central departments. The aim was to create a workable state after Venezuela and Ecuador had set up their own governments. This step shifted the process from trying to save Gran Colombia to legally replacing it.
A convention in Bogotá adopted an organic law that organized the central provinces as the State of New Granada. By changing the legal identity of the remaining core, this measure effectively ended Gran Colombia as a functioning state. It provided the legal bridge from the old union to a new national framework.
New Granada promulgated a new constitution in early 1832, replacing the old Cúcuta constitution that had structured Gran Colombia. This completed the legal transition from the union to successor states with their own constitutional orders. By this point, the dissolution had moved from regional declarations to final, recognized legal arrangements.
