Panama was one of the Departments of Colombia, created under the 1886 constitution.

Its predecessor was Panama State of the Republic of New Granada (1855–1858), the Granadine Confederation (1858–1863) and United States of Colombia (1863–1886).

In 1903, it achieved independence as the modern Republic of Panama with the concession of the Panama Canal Zone to the United States.

Colombia did not formally recognize the sovereignty of Panama until 1909.
