TL;DR: Mathematician Hari Seldon uses “psychohistory,” a science of predicting mass human behavior, to foresee the fall of the Galactic Empire and 30,000 years of chaos. To shorten the dark age to 1,000 years, he creates the Foundation on the distant planet Terminus. Over generations, its leaders face crises that Seldon predicted.

What Happens, Part by Part (Contains Spoilers)
The Psychohistorians
Gaal Dornick arrives on Trantor, the Empire's capital, to work with Hari Seldon. Seldon is on trial for predicting the Empire's fall. He persuades the authorities to exile his followers to Terminus, at the edge of the galaxy, to compile an Encyclopedia Galactica.
The Encyclopedists
Fifty years later, Terminus is threatened by the breakaway kingdom of Anacreon. The Encyclopedists are powerless. Salvor Hardin takes control. A recorded hologram of Seldon reveals that the encyclopedia was a cover and that the Foundation's true purpose is to rebuild civilization.
The Mayors
Thirty years later, Hardin keeps the surrounding kingdoms in check by giving them advanced technology but wrapping it in mystical ritual, so that they depend on the Foundation's trained technicians. When Anacreon attacks, the technicians refuse to obey, and the threat collapses.
The Traders
Foundation traders spread technology and influence through commerce. A trader named Limmar Ponyets uses clever trade to free a captured colleague.
The Merchant Princes
Hober Mallow faces the Republic of Korell, which has advanced weapons from the remains of the Empire. He builds economic dependence on Foundation gadgets and wins without a battle, because when trade stops, Korell's people demand peace. Mallow becomes the Foundation's leader.
