who was the shortest reigning monarch of england
List of British monarchy records The shortest-reigning monarch was Lady Jane Grey who ruled for 9 days from 6 July until 15 July 1553 (although she was only proclaimed queen by the Lords of the Council on 10 July). Note: Jane's reign is disputed.
Monarchy of the United Kingdom In 1714, Queen Anne was succeeded by her second cousin, and Sophia's son, George I, Elector of Hanover, who consolidated his position by defeating Jacobite rebellions in 1715 and 1719. The new monarch was less active in government than many of his British predecessors, but retained control over his German kingdoms, with which Britain was now in personal union.[58] Power shifted towards George's ministers, especially to Sir Robert Walpole, who is often considered the first British prime minister, although the title was not then in use.[59] The next monarch, George II, witnessed the final end of the Jacobite threat in 1746, when the Catholic Stuarts were completely defeated. During the long reign of his grandson, George III, Britain's American colonies were lost, the former colonies having formed the United States of America, but British influence elsewhere in the world continued to grow, and the United Kingdom of Great Britain and Ireland was created by the Acts of Union 1800.[60]
