The
United States of Colombia was the name adopted in 1861 through the Rionegro Constitution for the
Granadine Confederation, following years of civil war. Colombia became a federal state itself composed of nine "sovereign states". It comprised the present-day nations of
Colombia and
Panama and parts of northwestern
Brazil. After several more years of intermittent civil wars, it was replaced by the more centralist
Republic of Colombia in 1886.
