The Victorian Age in Britain lasted from 1837 to 1901, during which Queen Victoria reigned for 64 years as a constitutional monarch. This was a period of British imperial expansion that saw the empire grow to include Australia, India, and many other territories. It was also a time of rapid industrialization, urbanization, and cultural development, though there were also challenges like the Irish Famine and demands for independence from parts of the empire. Overall, the Victorian Age marked a major period of transition as Britain transformed into a modern industrial and imperial world power.
