William Lamport, Emperor of Mexico

[numberone]

William Lamport, aka El Zorro, tried to convince Mexicans to establish him as emperor. His attempt to install himself failed, and he ws executed.

But, how could he become the Emperor; and what would have changed historically?

Information on him is on Wikipedia, if one needs a place to look him up.

Edit: He tried to convince the New Spanish, as modern day Mexico was still under Spain's control.
