uchronian adj.

All Times Possible is a uchronian novel about America as it could easily have been had there been some slight divergencies [sic] in the political currents of the past few decades.

[‘]History refashioned logically as it could/might have been.’ In English uchronia and uchronian will do for the thing described, by analogy with utopia.

Uchronian sf thus developed independently of the tradition of time travel and time paradoxes in Anglo-American sf; indeed, the first important work on the time travel-theme is found in Rene Barjavel’s Future Times Three (1943), in which the paradox of a man’s killing his ancestor is developed rather laboriously.

We would be dealing not with a historical novel, apparently, but with one of those stories that are called uchronian—”that take place in a historical time all upside down, where Julius Caesar fights a duel with Napoleon, and Euclid finally manages to demonstrate Fermat’s theorem.

Finally, Conner slyly plays the uchronian game by inserting several references to the fates of Gertrude Stein, Ernest Hemingway, and Scott Fitzgerald, among others.
