Isthmus Department
The Isthmus Department, or Department of Panama, was one of the departments of the Republic of Gran Colombia and later of the Republic of Colombia. It was created in 1824 and named after the Isthmus of Panama. It covered the territory of what is now the country of Panama and some coastal territories farther northward along the Caribbean shoreline of present-day Costa Rica and Nicaragua.
After the Thousand Days' War and the influence of the United States to build the Panama Canal the former Department of Gran Colombia separated from Colombia and became the Republic of Panama.History
The region of Panama was part of the Spanish empire during the wars of independence against the Spanish. After the patriot victory at the Battle of Carabobo, Panamanians decided to join Gran Colombia. Up until this point, Panama had remained within the Spanish monarchy and had avoided the troubles afflicting the rest of the Viceroyalty of New Granada. On November 28, 1821 Panama was voluntarily annexed to Gran Colombia under the Constitution of Cúcuta, which had been promulgated on August 30, 1819.
Francisco de Paula Santander as vice president on duty gave birth to the first Department of Panama which he also divided into two provinces: Panamá and Veraguas.
