As the Galactic Empire begins its long decline, mathematician Hari Seldon uses the science of psychohistory to predict the coming dark age and establishes the Foundation on a remote planet to preserve civilization and shorten the period of chaos from thirty thousand years to one. Told through a series of linked stories spanning generations, the novel follows the Foundation's crises and political maneuverings as it navigates the collapse around it. A cornerstone of science fiction, sweeping in scope and propelled by ideas rather than action.
