The Governor-General was the highest ranked office in the North American Union. The Governor-General represented the King-Emperor (or Queen-Empress) of Britain and the Empire in the Union. Notable Governors-General oversaw the establishment of protected Red Indian nations within the Union, westward expansion of Union domains to the Pacific Ocean, the abolition of slavery and the establishment of racial equality, the defeat of Franco-Spanish and Russian conspiracies to harm the empire from without, and the suppression of white supremacist uprisings from within. The Governor-General's residence in Victoria was known as America's Number 10 after its London model.
