what's grao-para supposed to be?
The Captaincy of Grão-Pará, or just Pará, has its origins in the context of the conquest of the Amazon River, a period of conflict with foreign forces. The region was first called with the terminology of Conquista do Pará, but the term Rio das Amazonas is also used. The oldest document that mentions the term captaincy, to name the region of conquest, dates back to the year 1620. Therefore, the legitimacy of the territory as Captaincy only occurs in parallel with the creation of the State of Maranhão, in the year of 1621.
The Province of Grão-Pará, which at the time was commonly called Pará (from the Tupi-Guarani, Sea River or Great River), was an administrative unit from the end of the colonial period and the Brazilian imperial period, originated from the captaincies of the Grão- Pará and the Rio Negro. It existed from 1821 to 1889. The Portuguese initially called the territory "Terra de Feliz Lusitânia" (Land of Happy Lusitania) , soon replaced by Grão-Pará, and finally became just Pará in 1889.
The process of political rupture between Brazil and Portugal created, in the province of Grão-Pará, a situation of uncertainty. In 1821, the captaincy of Rio Negro was elevated to a province, like all other captaincies. However, the Rio Negro was not included among the provinces of the Empire in the Constitution of 1824. Its situation would only be defined in 1833, when the Criminal Code demoted it to the legal status of a district subordinate to the province of Pará. The region would only regain its autonomy in 1850, with the creation of the province of Amazonas.
Grão-Pará was the main starting point and support for the irradiation of Portuguese penetration in the north coast of Brazil, expanding and acquiring, especially between 1580 and 1616, the date of the expulsion of the French and the definitive incorporation of these territories to the crown of Portugal.
