It has been put that the people of Oldham became radical in politics in the early part the 19th century , and movements suspected of sedition found patronage in the town . Oldham was frequently disturbed by bread and labour riots , facilitated by periods of scarcity and the disturbance of employment following the introduction of cotton-spinning machinery . On 20 April 1812 , a " large crowd of riotous individuals " compelled local retailers to sell foods at a loss , whilst on the same day Luddites numbering in their thousands , many of whom were from Oldham , attacked a cotton mill in nearby Middleton . John Lees , a cotton operative , was one of the victims of the '' Peterloo Massacre '' of 1819 , and the ' Oldham inquest ' which followed was anxiously watched ; the Court of King 's Bench , however , decided that the proceedings were irregular , and the jury were discharged without giving a verdict . Annie Kenney , born in nearby Springhead , and who worked in Oldham 's cotton mills , was a notable of the Suffragette movement credited with sparking off suffragette militancy when she heckled Winston Churchill , and later ( with Emmeline Pankhurst ) the first Suffragist to be imprisoned . Oldham Women 's Suffrage Society was established in 1910 with Margery Lees as president and quickly joined the Manchester and District Federation of the National Union of Women 's Suffrage Societies . The Chartist and Co-operative movements had strong support in the town , whilst many Oldhamers protested against the emancipation of slaves . The Riot Act was read in 1852 on election day following a mass public brawl over the Reform Act , and irregularities with parliamentary candidate nominations
