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. The village of Realengo was limited by the Senate of Rio de Janeiro, by the provision of July 18, 1814, taking over the Court of the lands tested on the Estrada da Santa Cruz (Road of Saint Cross) and depths of more than twenty fathoms. Despite the express prohibition of lease, sale or other disposition, the Senate, after a certain time, taking advantage of the charter of June 27 has all land granted for such reasons that in addition to the ordinance November 20, 1815 the Prince Regent known as royal notice, on December 20, 1815 that allowed only the tenure of the party which was tested on the Estrada de Santa Cruz (and depths of 20 fathoms the maximum, not at all Realengo). The neighborhood had its first settlers, slaves and immigrants from the Portuguese island of the
Azores, by order of the Prince Regent Dom João, later
Dom João VI. When they devoted themselves to agriculture for grazing leading products such as sugar, molasses, alcohol and rum, the port of Guaratiba. Research shows that there was only one mill in Realengo as everything was taken to undergo transformation into other properties. On April 7, 2011, 23-year-old gunman
