he Viceroyalty of New Spain was the name of the viceroy-ruled territories of the Spanish Empire in North America and its peripheries in Asia from 1535 to 1821.New Spain was the name that the Spanish gave to the area that today is central and southern Mexico, and since the capital city of the Viceroyalty was in Mexico City, the name was also used for the viceroyalty.

The Viceroyalty of New Spain's territory included what is the Bay Islands (until 1643), Cayman Islands (until 1670), Central America (as far as the southern border ofCosta Rica unti

Spain claimed areas as far north as British Columbia and Alaska, but the northern boundary of New Spain was redefined by the Adams-Onís Treaty of 1819. Until 1739, New Spain also included Venezuela.

In 1821, Spain lost continental territories when it recognized the independence of Mexico, as well as Santo Domingo when it was invaded by Haiti that same year. However, Cuba, Puerto Rico and Spanish East Indies (including Mariana Islands and the Philippines) remained a part of the Spanish crown until the Spanish–American War (1898).
