Cylon of Croton
Cylon of Croton was a leading citizen of Croton, who led a revolt against the Pythagoreans, probably around 509 BC. According to Iamblichus' De Vita Pythagorae, Cylon had previously tried and failed to be accepted into the Pythagorean order ; however, the clearly pro-Pythagorean bias of Iamblichus' work means we should take this with a grain of salt. In the climactic moment of the revolt, a meeting house was set on fire as the Pythagoreans were debating inside - according, again, to Iamblichus. After the success of the rebellion, all debts owed were eliminated and property was seized for redistribution; this arguably resulted in Pythagoras being expelled from Croton.
