It is difficult to answer because the world is such a different place now than it was even fifty years ago, let alone two-hundred years ago. The concept of a non-violent revolution is a distinctly modern, later half twentieth-century one. The idea was not a possibility previously, and as such, violent revolutons have been far more successful throughout history.
However, in recent times, it can be very easily argued that the non-violent type have been as successful, if not more so. Sell all of the 'color' revolutions as evidence.
