Long ago on a distant world, humans were enslaved by an ancient race, and so were spread across the galaxy to almost all the worlds of the Infinite Empire. When that empire fell, humans were just... basically everywhere. So when hyperdrives were invented, and the planets became able to interact again, humans were the majority race in the galaxy, not counting microscopic lifeforms.
