Seldon Crisis

A Seldon Crisis is a fictional socio-historical phenomenon in Isaac Asimov's Foundation Series of science fiction novels. They are part of the field of psychohistory, and refer to a social and political situation that, to be successfully surmounted, would eventually leave only one possible, inevitable, course of action.

They are named after Hari Seldon, who founded the field of psychohistory, and who appears as a pre-recorded hologram at the climax of each crisis. Before his death, he used psychohistory to predict and manipulate each event. A Seldon Crisis usually involves both an external pressure (such as threat of attack) and an internal pressure (such as threat of revolt). Both pressures will come to a head simultaneously, and be resolved with the same action.
