Why did the women suffrage movement in great britain become so militant?

Because the men at this time did not want the women to become more powerful than them they felt that the women did not have the copacity to move higher up on the "scale".

Some of the suffragettes became frustrated by how long it was taking to get the vote, and believed that more aggressive tactics would help. The majority of suffragettes did not support the militant wing.

You did your part you!
