20th Century
On April 26, 1901, it was restored under the name of Territorio Federal Delta Amacuro, composed of the districts of Barima and Tucupita. After this year its political division varied from districts and departments to municipalities. Its capital was moved to Tucupita, a city formerly known as Cuarenta y Ocho.
During this time, multiple religious orders of Catholic affinity made their way into the region. In 1925 a new Catholic religious order, called Capuchinos del Caroní, -whose mission at that time included the Delta Amacuro Territory- founded the first of the current missions,
The Catholic missionary Barral settled in the area in the 1930s and established a mission in Guayo. In the following decades he collected information on the Warao language and published a Spanish-Warao dictionary.
From 1932 onwards, other missionaries founded new missions in San José de Tucupita, San Francisco de Guayo, Nabasanuka and Ajotejana. In 1940 the Organic Law of the Federal Territory Delta Amacuro was promulgated, which divided it into the departments of Tucupita, Pedernales and Antonio Díaz. According to the Extraordinary Official Gazette No. 4,295 of August 3, 1991, the Special Law was promulgated, giving the Territory the status of State, with the same political-territorial division as before.
On January 25, 1995, the State Legislative Assembly issued its second Law of Political Territorial Division, with the 4 current municipalities; it also annexes to the state the hamlets Nuevo Mundo, Platanal, El Triunfo and El Triunfito, previously under the jurisdiction of the State of Bolivar.
