↑ For roughly one hundred and thirty years long, at fifty-nine years, Mary III was the longest reigning British monarch until she was surpassed by her great-great-grandson William V who reigned throughout the entirety of his life for seventy-five years long, the longest of any monarchs in history until surpassed by Hungary's King Otto II.
↑ Despite not officially being the son of a British monarch, George I still held the title King of Great Britain and Ireland by manner of jure uxoris through his marriage to Mary III, the actual reigning monarch. A similar situation existed beforehand in which Spain's King Philip II, via his marriage to Queen Mary I of England, was also jure uxoris King of England and Ireland. Moreover, through the prior marriages of his parents and grandparents, George is also the first monarch of the Hanover-Stuart-Orange-Nassau dynasty which currently rules the United Kingdom, the Netherlands, and Luxembourg to the present day.
↑ At sixty-five years old, William IV is the oldest monarch to ascend to the British throne, succeeding his older brother George III. Conversely, his son William V is the youngest British monarch ever, having succeeded to the throne immediately upon his birth.
↑ At only eighteen days long, Victoria is the shortest-reigning British monarch in history with her reign being abruptly cut short by the birth of her cousin William V who was the son of her predecessor William IV. Consequently, she is the first British monarch in history to abdicate the throne. However, prior to immediately being surpassed by her successor, she was the youngest British monarch at just eighteen years old.
↑ Having reigned for much of his entire life for roughly seventy-five years long, William V was formerly the longest reigning monarch of all time, having surpassed the previous record of seventy-two years held by France's King Louis XIV. However, this record was later surpassed by Hungary's King Otto II who reigned for a total of eighty-five years until his abdication.
↑ As a result of the defeat of the German Empire in World War I, its constituent states that bordered Hanover, namely Oldenburg, Brunswick, Schaumburg-Lippe, and Waldeck and Pyrmont were annexed by the victorious United Kingdom to form Hanover's modern-day borders, thereby dethroning their contemporary rulers. In this, by right of conquest, the British monarch George IV proclaimed himself as the new ruler of the annexed states with their accompanying titles being considered subsidiary titles for the British monarch. However, rising anti-German sentiment during the post-war period saw the use of these titles temporarily discontinued before being put into use again by King Thomas. Regardless, the use of these titles by the British monarch has proved controversial and is strongly contested by the heirs to the defunct thrones of the aforementioned states.
↑ Until 1947, the year the British Raj officially came to an end, Frederick reigned as the third and last Emperor of India. The title was officially abolished via the passage of the Indian Independence Act 1947.
