On a global scale, I think there's an argument to be made that the fight never ended at all.

But, on a local scale, Chile comes to mind. Pinochet was ousted democratically and the military dictatorship ended. But that was only really because Pinochet was willing to relinquish control (due to external factors mostly, not just some change of heart) which isn't exactly common for fascist and authoritarian leaders, so Im not sure if that example applies much generally.
