Nuevespañolan War

The Nuevespañolan War was fought between the British Empire and the Franco-Spanish Holy Alliance in the early 1860s. It resulted in American annexation of territory from Nueva España which became the Provinces of Cranmer, Phoenix, Upper California, and Lower California. The international borders established at the end of this war remained in force in the late 20th century. Although the Nuevespañolans still expressed some bitterness about the long-ago loss, they never made any serious effort at reconquest, expressing their discontent only by petty acts of subversion and sabotage.

Literary comment
The authors of The Two Georges do not give this war a name. "Nuevespañolan War" is a designation of convenience. Nor are the precise dates given, however the opening chapter says that, as of 1995, it is "a century and a third" since New Liverpool, née Los Angeles, was incorporated into the NAU.
