Victoria (Alexandrina Victoria) (24 May, 1819 – 22 January, 1901) was the eminent Queen of the United Kingdom of Great Britain and Ireland from 20 June, 1837, and Empress of India from 1 January, 1877, until her death in 1901. Her reign lasted more than sixty-three years, longer than that of any other British monarch. As well as being Queen of the United Kingdom of Great Britain and Ireland, she was also the first monarch to use the title Empress of India. The reign of Victoria was marked by a great expansion of the British Empire. The Victorian Era was at the height of the Industrial Revolution, a period of significant social, economic, and technological change in the United Kingdom. In that period the United Kingdom became the largest superpower the world had ever seen. Victoria, who was largely of German descent, was the last monarch of the House of Hanover; her successor belonged to the House of Saxe-Coburg and Gotha.
