d Conservative parties, founded in 1848 and 1849 respectively, are two of the oldest surviving political parties in the Americas.
Internal political and territorial divisions led to the secession of Venezuela and Quito (today's Ecuador) in 1830. The so-called "Department of Cundinamarca" adopted the name "Nueva Granada", which it kept until 1856 when it became the "Confederación Granadina" (Granadine Confederation). After a two-year civil war in 1863, the "United States of Colombia" was created, lasting until 1886, when the country finally became known as the Republic of Colombia. Internal divisions remained between the bipartisan political forces, occasionally igniting very bloody civil wars, the most significant being the Thousand Days' War (1899–1902).
This, together with the United States of America's intentions to influence the area (especially the Panama Canal construction and control) led to the separation of the Department of Panama in 1903 and the establishment of it as a nation. The United States paid Colombia $25,000,000 in 1921, seven years after completion of the canal, for redress of President Roosevelt's role in the creation of Panama, and Colombia recognized Panama under the terms of the Thomson-Urrutia Treaty. Colombia was engulfed in the Year-Long War with Peru over a territorial dispute involving the Amazonas Department and its capital Leticia.

Soon after, Colombia achieved a relative degree of political stability, which was interrupted by a bloody conflict that took place between the late 1940s and the early 1950s, a period known as La Violencia ("The Violence"). Its cause was mainly mounting tensions between the two leading political parties, which subsequently ignited after the assassination of the Liberal presidential candidate Jorge Eliécer Gaitán on 9 April 1948. The ensuing riots in Bogotá, known as El Bogotazo, spread throughout the country and
