Presidential elections were held in the United States of Colombia in 1865 and February 1866. The electors were elected in 1865 and elected the president the following year. The result was a victory for Tomás Cipriano de Mosquera of the Liberal Party.[1]
The 1863 constitution changed the electoral system from a direct vote to an indirect vote. The President was now elected on the basis of which candidate received the most votes in each state, with a candidate required to win in at least five of the nine states to be elected. If no candidate received a majority, Congress would elect the President from the main contenders.[2]
