Manchester Female Reform Society was formed in July 1819 to spread democratic ideals.
In early July 1819 the Blackburn Female Reform Society was established. They sent a circular to other districts, inviting the wives and daughters of the workmen in the different branches of manufacturing to form themselves into similar societies. So on 20 July 1819 numerous women of Manchester formed themselves into a Society of Female Reformers. The secretary was Susanna Saxton and the President was Mary Fildes who was on the platform with Henry Hunt, the key orator at the Peterloo Massacre. The Society flag had the figure of Justice on it. In the first week of the formation of the Society 1000 members joined it. Little is known about the progress of the Society. The next mention of Mary Fildes is in the Poor Man's Guardian in 1833 that she co-founded, with Mr Broadhurst, the Female Political Union of the Working Classes.
