New Spain is not to be confused with the Spanish imperial office of the Viceroy of New Spain. New Spain was a geographical territory, whereas “viceroy” refers to the political position of a man.
Originally based out of the original colony of Buenos Aires the Viceroyalty of New Spain was created after a few decades of expansion of Buenos Aires left a sprawling series of coastal settlements which were becoming hard to individually manage as well as a conquered local nation known as the Mapuche. The Viceroy an established member of the Royal family for the most part, ruled the colony in place of the Monarch of Hispania and for the most part embarked on an aggressive coastal settlement policy aimed at reaching the Straits of Torres, and then up the east coast of Hesperia.
The Colony itself as of 1539 maintains a population of just over 200,000 and maintains a thriving economy based around ranching of cattle, and sheep, as well as a few plantations and a budding Silver exportation business. Along with this New Spain's biggest port of Buenos Aires is growing trade hub of the continent and is a major stopping point for treasure ships sailing from the Protectorate of the Inca and now more recently the Aztec and Zapotec areas in Central Borelia. The Viceroyalty of New Spain is also continuing to expand through various areas and has an expansive settlement further up the coast known as San Sorento.
In the Following years from the establishment of the colony to its expansionary and conquesting natives phases the Colony of New Spain has been not only a haven for those wishing for more freedom or economic opportunity, but an all around paradise for many of the nobility of the Spanish Empire Particularly with nearly 12 secondary or "cadet" branches of the Spanish Habsburgs living within the Colonial viceroyalty
