Feargus Edward O’Connor, advocate of the Land Plan and prominent Chartist leader who succeeds in making Chartism the first specifically working class national movement in Great Britain, is born near Castletown-Kinneigh, County Cork on July 18, 1796.

O’Connor is born into a prominent Irish Protestant family who claims to be the descendants of the 12th-century king Ruaidrí Ua Conchobair. He is educated mainly at Portarlington Grammar School and has some elementary schooling in England.

O’Connor practices law but exchanges law for politics when he enters the British Parliament in 1832 as a member for County Cork. Unseated in 1835, he turns to radical agitation in England, although he continues to press Irish grievances and to seek Irish support. As a result of his humour, invective, and energy, he becomes the best known Chartist leader and the movement’s most popular speaker. His journal, the Northern Star (founded in 1837), gains a wide circulation.

O’Connor’s methods and views alienate other Chartist leaders, particularly William Lovett, but in 1841, after spending a year in prison for seditious libel, he acquires undisputed leadership of the Chartists. Failing to lead the movement to victory and vacillating in his attitude toward the middle class and toward the People’s Charter, a six-point bill drafted and published in May 1838, he begins to lose power, although he is elected to Parliament for Nottingham in 1847. The failure of the People’s Charter in 1848 marks the beginning of the end for O’Connor, whose egocentricity is already bordering on madness.

The circulation of the Northern Star falls steadily and it loses money. O’Connor’s health is failing, and reports of his mental breakdown regularly appear in the newspapers. In the spring of 1852 he visits the United States, where his behaviour leaves no doubt that he is not a well man.

In 1852 in the House of Commons O’Connor strikes three fellow MPs, one of them Sir Benjamin Hall, a vocal critic of the Land Plan. Arrested by the Deputy Sergeant-at-Arms, he is sent by his sister to Dr. Thomas Harrington Tuke‘s private Manor House Asylum in Chiswick, where he remains until 1854, when he is moved to his sister’s house. He dies on August 30, 1855 at 18 Albert Terrace, Notting Hill Gate and is buried on September 10 in Kensal Green Cemetery. No fewer than 40,000 people witness the funeral procession. Most Chartists preferred to remember O’Connor’s strengths rather than his shortcomings.
