I'm not sure what you count as violence, but if you look at the history of the suffrage movement in Britain, you will find that while the movement started out as non-violent, it escalated to include campaigns of window-breaking, arson, and other destruction of property. (Women were also involved in many violent confrontations with police, but it looks like the police always initiated the violence. To what degree women responded in kind and whether that would make their movement violent is unclear to me.) The historians usually describe the vandalism campaigns as violent, militarism, or both, though maybe you meant to restrict attention to violence against persons. Of course, the women agitating for the vote suffered much more violence than they inflicted.
