Teetering at the edge of the new century, the Manchester Society for Women's Suffrage found itself wanting to gain traction on a different level than before, and to discuss and share with their fellow suffragists on a more broad scale.  The invitation to join (or rather, to assist in the formation) the National Union of Women's Suffrage Societies along with 500 other bustling organizations was fondly received.  The NUWSS stayed in high regard until some of the more active women - Emmaline Pankhurst, key member of the MSWS - split to start the Women's Social and Political Union.  Regardless, the MSWS and other organizations stayed, renaming themselves the North of England Society for Women's Suffrage just to return to their original name.  As such, the NUWSS continued their efforts well into the 20th century, aided by many of those original 500 or so groups that they encompassed.
