Microworld

Microworld, 1970
Divergence: 1892; everyone shrinks to 1 inch tall
The now much smaller human race recovered, after a few wars of extermination against un-shrunken rats and the like. They even fought a war against expansionist Microhungary in the 1920s. They have undergone some nuclear research, but the smallest possible bomb is still very difficult for inch-tall people to build.
