Hostess of San Carlos Palace
The Hostess of San Carlos Palace was the unofficial position held by the wives of the presidents in the now-defunct states of Gran Colombia, New Granada, the Granadine Confederation, and the United States of Colombia. This role is considered the precursor to the role of First Lady of Colombia, which was formalized in 1886 with the founding of Colombia.
