19th century Anglo-French conflicts during the French Revolutionary and Napoleonic Wars, which lasted from 1793 until 1815, saw the rise of anti-Catholicism as an underlying method to unify the Protestant populations of England, Scotland and Wales. Permeating through all social classes, antagonism towards Catholicism became firmly enmeshed with British national identity. As noted by English historian Linda Colley in her seminal work Britons: Forging of a Nation 1707–1837, the "defensive unity brought on by war with a Catholic French 'other' helped transform Great Britain from a new and largely artificial polity into a nation with a strong self-image rooted in Protestantism." Catholics in Ireland gained the right to vote in the 1790s but they were politically inert for another three decades. Finally, they were mobilized by Daniel O'Connell into majorities in most of the Irish parliamentary districts. They could only elect, but Catholics could not be seated in parliament. The Catholic emancipation issue became a major crisis. Previously anti-Catholic politicians led by the Duke of Wellington and Robert Peel reversed themselves to prevent massive violence. All Catholics in Britain were "emancipated" in the Roman Catholic Relief Act 1829. That is, they were freed from most of the penalties and restrictions they faced. Anti-Catholic attitudes continued, however. Since 1945 Since World War II, anti-Catholic feeling in England has abated somewhat. Ecumenical dialogue between Anglicans and Catholics culminated in the first meeting between an Archbishop of Canterbury and a Pope since the Reformation when Archbishop Geoffrey Fisher visited Rome in 1960. Since then, the dialogue has continued through envoys and standing conferences. Meanwhile, both the nonconformist churches such as the Methodists, and the established Church of England, have dramatically declined in membership. Membership in the Catholic Church continues to grow in Britain, thanks to the immigration of Irish and more recently, the immigration of Polish workers. Conflict and rivalry between Catholicism and Protestantism since the 1920s, especially since the 1960s, has centered on the Troubles in Northern Ireland. Anti-Catholicism in Britain was long represented by the burning of an effigy of the Catholic conspirator Guy Fawkes during widespread celebrations of Guy Fawkes Night every 5 November. However, this celebration has lost most of its anti-Catholic connotations. According to Clive D. Field, only faint remnants of anti-Catholicism are found today. Ireland As punishment for the rebellion of 1641, almost all of the lands which were owned by Irish Catholics were confiscated and given
