The so-called Terras originated, according to some historians, with the Carta Régia (Royal Charter) of June 27, 1814, by which John VI of Portugal, also a prince, gave land grants in the Senate of Rio de Janeiro land situated in Campo Grande (Big Field). These were called realengos, or royal lands, arising because of territorial conquest by the discovery of the country; they were not ordinary real estate. The land grant in what is now the Realengo neighborhood, center and periphery, was intended to serve only for grazing cattle, supplying meat to butchers in the city. These lands were banned from any sale by the disposition requiring that the Senate survey and prepare them to serve the purpose for which they were donated by that charter.
