The Central District of the Gran Colombia, known as Cundinamarca or New Granada (modern Colombia) with its capital in Bogota, did not recognize the separation of the Southern District of the Gran Colombia, with its capital in Quito, from the Gran Colombian federation on May 13, 1830. After Ecuador's separation, the Department of Cauca voluntarily decided to unite itself with Ecuador due to instability in the central government of Bogota. The Venezuelan born President of Ecuador, the general Juan José Flores, with the approval of the Ecuadorian congress annexed the Department of Cauca on December 20, 1830, since the government of Cauca had called for union with the District of the South as far back as April 1830. Moreover, the Cauca region, throughout its long history, had very strong economic and cultural ties with the people of Ecuador. Also, the Cauca region, which included such cities as Pasto, Popayán, and Buenaventura, had always been dependent on the Presidencia or Audiencia of Quito.
