Alternate history

THE BEST OF TODAY’S ALTERNATE HISTORY ISN’T LIKELY TO CHEER YOU UP. BUT IT CERTAINLY WON’T BORE YOU.

People have been writing alternate history since at least the early nineteenth century, but for most of that time, it was a tiny sub-genre of popular fiction. Now it’s being produced in industrial quantities.

Conjectural or speculative history can be a silly game, as in “What if the Roman legions had machine guns?” But this historian argues that to enlarge our knowledge and understanding it sometimes makes very good sense to ask …

What if any of the pre-Civil War Presidents had gone mad? What if Andrew Johnson had been successfully impeached? What if William McKinley had not been assassinated?
