Spanish Empire is a name for the holding of the rulers of Spain in America. Expansion was at its peak during the reign of Joanna I. It is de facto controlled by the Duke of Mexico from Florida, though the capital is the ciry of New Toledo in Yucatan.
Officially the Spanish Empire came into full existence in 1520, when the Aztec Triple Alliance was annexed following the death of Montezuma II. After that all expansion was mostly toward north. By 1540s they reached Rio del Norte (Rio Grande) where their expansion changed direction to either sides. The eastern voyages made sure that by 1545 all Caribbean Islands become a part of the Empire. In 1546 Joanna I of Spain ordered a new capital to be build on the Yucatan Peninsula. Hernán Cortés died in 1547 on his invasion of Florida which was later annexed in 1548 by his successor Luis de Léon, who also lead the Mexican Campaign of 1549 against the Chumash and Apache, this was, however, a disaster. Later in 1550 the new capital called New Toledo is build on the Yucatan Peninsula and Joanna I of Spain appoints Martín Cortés the Duke of Mexico.
Spanish Empire is considered a monarchy with the Spanish Monarch as its head. However, de facto the Duke of Mexico actually rules the Empire, there is not an official power base as the Cortés' home is not in New Toledo (a special mayor lives there), but in Florida where they have huge tracks of land which generate wealth, making them the second most powerful family in the world after the Habsburgs.
Culture and Religion
Between 1520 and 1550 all of the Empire was a subject of intense Christianisation under the Spanish causing discomfort of the Aztecs. They were also expelled from their original cities which were almost entirely destroyed, this also included some written records, but some where conserved. A cathedral in New Toledo had many records until 1560, when they were carried back to Europe.
