Holford, Castello N. Aristopia. A Romance-History of the New World
Divergence: c 1607 CE
What if: The first settlers in Virginia discovered a reef of pure gold and set up a Utopian colony.
Summary: History of the land of Aristopia, from its founding to its final takeover of North America 300 years later.
Comments: One of a tiny number of alternate history novels published before 1900. Virtually impossible to find in print as it was apparently published by a vanity press, but is now available on-line.
Published: Arena 1895.
