Tychē as a Force in History

τύχη

Fortune treated not as a metaphor but as a real power actively steering the rise and fall of states.

Tyche means Fortune or chance, which Hellenistic and later historians invoked as an active agent shaping outcomes beyond human control. Polybius (2nd c. BCE) repeatedly credits Tyche with guiding Rome to world dominion — sometimes as genuine chance, sometimes as a near-providential ordering force — while later writers such as Procopius (6th c. CE) wrestle with Fortune's caprice. The concept let historians explain dramatic reversals that planning alone could never account for.
