A decree signed on 26 April 1822 signed by the Marquis of Torre Tagle, transformed what once was the General Command of Maynas into the Quijos Department, allowing it to also choose deputies. In 1925, Maynas was integrated into the Department of La Oroya.
In 1822, Joaquín Mosquera travelled on behalf of Colombia to request the restitution of the province. On July 25, 1824, the Congress of Gran Colombia issued a law of territorial division intending to include the Canton of Quijos in the Pichincha Province of the Department of Quito, according to the limits it had at the time of creation as the Viceroyalty of New Granada. It also intended to incorporate the Provinces of Jaén, Matamoros and Maynas into the Department of Azuay. The Peruvian refusal to give up the territories escalated tensions between the two countries, culminating in the Gran Colombia–Peru War.
Due to a law made effective on November 21, 1832, Maynas was integrated into the territory of the new Peruvian department of Amazonas, from which it separated in 1853, when a political government was created in the Loreto region.
According to the 1993 Census, the Maynas Province has a population of 393,496 inhabitants, 50.6% of which (199,209) are male and 49.4% (194,287) are female.
The majority of the province's residents (96%) speak Spanish at home; other languages spoken are Quechua (2%), Aymara (150 speakers, 0.0%), other indigenous languages (0.8%) and foreign languages (0.2%).
Immigration
Persons originating from other regions of the country make up 8.4% of the population and 0.3% of residents were born abroad.
Secondary education has been attended by 28.8% of the population and 2.5% also have graduated from non-university higher education, while 2.6% have complete university studies. 46.7% only have attended primary education and 8.5% have not had any education.
The province is divided into eleven districts (Spanish: distritos, singular: distrito), each of which is headed by a mayor (alcalde). The districts, with their capitals in parentheses, are:
