In the history of the United Kingdom, the Victorian era was the period of Queen Victoria's reign, from 20 June 1837 until her death on 22 January 1901. The era followed the Georgian period and preceded the Edwardian period, and its later half overlaps with the first part of the Belle Époque era of Continental Europe. In terms of moral sensibilities and political reforms, this period began with the passage of the Reform Act 1832. There was a strong religious drive for higher moral standards led by the nonconformist churches, such as the Methodists, and the Evangelical wing of the established Church of England. Britain's relations with the other Great Powers were driven by the colonial antagonism of the Great Game with Russia, climaxing during the Crimean War; a Pax Britannica of international free trade was maintained by the country's naval and industrial supremacy. Britain embarked on global imperial expansion, particularly in Asia and Africa, which made the British Empire the largest empire in history. National self-confidence peaked.
