Overview

The United States of Colombia was the radically federalist republic created by the Liberal-dominated Rionegro Convention and its Constitution of 8 May 1863. It represented the high tide of 19th-century Colombian liberalism and federalism: it granted the nine constituent sovereign states extensive autonomy, established a very weak central government with a short (two-year) presidential term, and enshrined sweeping individual liberties, freedom of the press, and anticlerical measures.

History

This period, sometimes called the "Radical Olympus," was marked by ambitious liberal reforms but also by chronic instability. The sovereign states maintained their own armies and fought frequent regional civil wars. The weak central government struggled to maintain order, and the extreme decentralization hampered national development, even as railways, education reform, and export agriculture advanced in places.

Decline and legacy

The era ended when the political tide turned against radical federalism. Rafael Núñez, a former Liberal who moved toward a movement of "Regeneration," allied with Conservatives and, after defeating a Liberal rebellion in 1885, declared the 1863 constitution defunct. The new Constitution of 1886 abolished the federal system, re-established a strongly centralized state, restored the power of the Catholic Church, and renamed the country the Republic of Colombia — the name it bears today.
