The Victorian era of British history was the period of Queen Victoria's reign from 20 June 1837 until her death on 22 January 1901. It was a long period of peace, prosperity, refined sensibilities and national self-confidence for Britain. Some scholars date the beginning of the period in terms of sensibilities and political concerns to the passage of the Reform Act 1832.

The era was preceded by the Georgian period and succeeded by the Edwardian period. The latter half of the Victorian age roughly coincided with the first portion of the Belle Époque era of continental Europe and the Gilded Age of the United States.

Culturally there was a transition away from the rationalism of the Georgian period and toward romanticism and mysticism with regard to religion, social values, and the arts. The era is popularly associated with the values of social and sexual restraint.

In international relations the era was a long period of peace, known as the Pax Britannica, and economic, colonial, and industrial consolidation, temporarily disrupted by the Crimean War in 1854. The end of the period saw the Boer War. Domestically, the agenda was increasingly liberal with a number of shifts in the direction of gradual political reform, industrial reform and the widening of the voting franchise.
