The controversy about Wood’s Halfpence between 1722 and 1725 was an exceptional instance of Irish defiance of England’s imperial authority. In a heated public dispute, more than 100 pamphlets and broadsides in prose and verse protested against the English Government’s granting a patent for coining copper money for Ireland to an English manufacturer. Castigating the project in economic and constitutional terms, they revealed an indebtedness to traditional arguments for Ireland’s status as a free kingdom, whose people enjoyed the same liberties as the people of England. The pamphlets thus render a representative picture of Irish political thought and of the country’s relationship with its closest neighbour, and most powerful rival, England, in the early eighteenth century.
