Queen Victoria surpasses her grandfather King George III as the longest reigning monarch in British history (later surpassed by her great-great-granddaughter Elizabeth II on 9 September 2015).

Victoria was Queen of the United Kingdom of Great Britain and Ireland from 20 June 1837 until her death in 1901. Her reign of 63 years and 216 days, which was longer than those of any of her predecessors, constituted the Victorian era. It was a period of industrial, political, scientific, and military change within the United Kingdom, and was marked by a great expansion of the British Empire. In 1876, the British parliament voted to grant her the additional title of Empress of India.

Elizabeth II was Queen of the United Kingdom and other Commonwealth realms from 6 February 1952 until her death. She had been queen regnant of 32 sovereign states during her lifetime and was the monarch of 15 realms at her death. Her reign of 70 years and 214 days is the longest of any British monarch, the second-longest of any sovereign state, and the longest of any queen regnant in history.

September 22 is the 265th day of the year in the Gregorian calendar; 100 days remain until the end of the year.
