The historical background of this municipality dates back to the foundation in 1724 of the mission of Purísima Concepción de Nuestra Señora del Caroní. Later, in 1817, General Manuel Piar established a command and won the Battle of San Félix against the royalist General La Torre.

In 1864, the Sovereign State of Guayana divided the territory into four departments: Ciudad Bolívar, Upata, Alto and Baixo Orinoco; San Félix is ​​not mentioned. At the end of the 19th century, the name of San Félix reappears and appears as a foreign municipality in the District of Piar. In the 1950s, the Companhia Mineira do Orinoco, at the confluence of the Orinoco and Caroní, established the infrastructure to explore the iron deposits of Cerro Bolívar.

In 1952 Puerto Ordaz is founded. In 1959, the Macagua I Dam came into operation. In 1960, the CVG was created. In 1961 Matanzas, Puerto Ordaz and San Félix were merged under the name Santo Tomé de Guayana (today Ciudad Guayana).
