We need to consult a historian. I think they'd say yes - there's also a few historians who would go further and say that suffragettes actually didn't do much at all - that it was politicians within the system who changed things. This seems uncharitable to me and slightly fishy also because the same (conservative) experts write that it's the left wing who tend to over emphasise the effects of on-the-streets protests and riots.

For me, I think it's a complimentary thing not an exclusive thing. For change to occur there's protests without and change within.
