In 1839, Cuffay was involved in the campaign which led to the Chartists presenting a petition to the parliament, which called for universal adult suffrage, no property qualification, annual parliaments, equal representation, payment of members, and vote by ballot. However, despite containing over a million signatures, the House of Commons rejected the petition by 235–46. There was widespread unrest after this motion, and about 500 Chartists were arrested. At the Newport Rising in November, several thousand Chartists attacked the Westgate Hotel and clashed with troops, who opened fire and killed 22 Chartists. Several Chartists leaders were arrested, including John Frost. Cuffay addressed a meeting of the Metropolitan Tailors' Charter Association, in which he spoke out in support of Frost. In response to the protests, the government commuted the sentences against Frost and his colleagues from death to transportation for life to Tasmania. In 1842, Cuffay was one of the Chartist leaders who presented another petition to parliament, containing the original six points, but also calling for Irish independence. This petition had over three million signatures, but it suffered the same fate, being rejected by 287–49. A series of strikes broke out as a result of the rejection of this petition. About 1500 Chartists were arrested, and approximately 600 were put on trial. Cuffay signed a letter to the Northern Star newspaper, seeking to raise funds for the prisoners on behalf of the Metropolitan Chartists. In 1843, at a Chartist meeting in High Holborn, Cuffay addressed the crowd, and thanked the working classes, on behalf of his relatives who were now freed slaves, for their support in helping to abolish slavery in the colonies. He said that he now dedicate himself to assist the working classes of Britain to gain their freedom.
Feargus O'Connor, the MP for
Nottingham, set up the
National Land Company, with the support of the Chartist movement. Cuffay was one of the auditors of the Land Company. Cuffay was one of the organisers of the large
Chartist rally on
Kennington Common on 10 April 1848, but was dismayed by the timidity of other leaders, such as O'Connor, who had rejected the idea that the rally should be a show of force. Cuffay's radical faction soon became involved in plans for a display of "physical force". Several hostile newspapers, including the
Times, the
Illustrated London News, and the
Standard used racist language in their attempts to denigrate the activism of Cuffay. It is also reported that Cuffay was a good singer, and sang at a number of Chartist events. He was often listed as a performer of the
Laughing Song by
William Blake for Chartist fund-raising events. ==Arrest and transportation==
