The family tree of the royal house of Hanover (officially known as the House of Brunswick-Lüneburg, Hanover line) that ruled Britain for 187 years (1714 - 1901). The Hanoverians were originally a long shot as the first of their British Kings, George Louis, elector of Hanover (aka George I of Great Britain), was, in 1714, only 52nd in line to the throne (although the nearest Protestant candidate according to the Act of Settlement). The dynasty went on to provide six monarchs until 1901 when Queen Victoria was succeeded by Edward VII from the house of Saxe-Coburg and Gotha (renamed the House of Windsor in 1917).
The history and lineage of the Royal House of Windsor (the reigning dynasty of the United Kingdom and the Commonwealth realms). The Windsors began when Edward, the eldest son of the last Hanover monarch, Queen Victoria, inherited the crown and the royal line changed over to the House of Saxe-Coburg-Gotha (from his father, Prince Albert). As World War One broke out in 1914, Britain, Russia, and Germany's monarchs were closely related. However, as anti-German sentiment rose at home, on July 17, 1917, George V of Britain issued a Royal proclamation changing the dynastic name to Windsor
