The Viceroyalty of New Spain (Spanish:
Virreinato de Nueva España), was the political unit of Spanish territories in North America and Asia-Pacific. The territory included a fort on Vancouver Island, the present-day Southwestern United States, Mexico, Central America (except Panama), the Caribbean, the Philippines, Guam and the Mariana Islands, and most of Micronesia.
It was ruled by a viceroy from Mexico City who governed on behalf of the King of Spain. The Viceroyalty of New Spain lasted from 1535 to 1821.
