The Victorian Era, the reign of Queen Victoria from her coronation on 20 June 1837 to her death on 22 January 1901, is known as a long period of peace, prosperity and national pride for the British Empire. It was a bold transition from the Georgian era, largely defined by logic, rationalism and a progression towards romanticism and mysticism in religion, societal values and the arts. In international relations, the Georgian era was widely regarded as a period of peace and Britain involved themselves in little external conflict. However, within the American colonies there was much unrest. In British domestic relations, the political agenda became increasingly liberal and was marked by shifts toward political, industrial and social reform. During the Victorian era, Britain experienced an unprecedented economic and population growth.
