Chronic rural disturbances have featured prominently in the modern history of Ireland. In particular, the period from the 1760s to the 1830s witnessed frequent and widespread disturbances, ranging over several counties and lasting for years. The disturbers — contemporaries sometimes called them ‘Whiteboys’ — were often sworn into secret societies which operated at night under the command of a mythical leader, known variously as Captain Right, Captain Steel or Captain Rock. Historical scholarship has shed light on many of these disturbances. However, the Rockites in the south of Ireland in the early 1820s remain somewhat mysterious. Although this was the only instance of rural unrest in Munster in the early 1820s, the Rockite movement nonetheless constituted one of the most extensive and serious rural disturbances in Ireland before the Famine. Five regiments of troops were dispatched from Britain, ‘for the purpose of putting down actual, & most formidable Danger in Ireland’, as the home secretary admitted. The Insurrection Act, with its curfew at night and trial without jury, was introduced into eight counties, and in its first year the act brought to trial more than 1,500 men in Munster, of whom more than 200 were convicted and transported. In County Cork, where the movement was at its most formidable, open engagements between thousands of the Rockites and the military occurred in several places, while incendiarism prevailed to an extent unprecedented in the history of Irish agrarian disturbances. The special commissions appointed in February 1822, specifically to try Rockites in the county, convicted thirty-six men of capital crimes.
