George V (George Frederick Alexander Charles Ernest Augustus; German: Georg Friedrich Alexander Karl Ernst August; 27 May 1819 – 12 June 1878) is King of Hanover, the only child of Ernest Augustus I, and a grandchild of King George III of the United Kingdom.

In the peerage of Great Britain, he is 2nd Duke of Cumberland and Teviotdale, 2nd Earl of Armagh.

He was the fifth and final King of Hanover.

George V, a first cousin of Queen Victoria, inherits the Hanoverian realm (which could not pass to Victoria because of Salic law) through his father, who had ascended the throne of Hanover in place of Victoria.

George spends his childhood in Berlin and in Britain, losing the sight of one eye following a childhood accident and illness in 1828.

He loses the sight in the other eye in 1833.

His uncle, William IV, creates him a Knight of the Garter on August 15, 1835.

His father had hoped that the young prince might marry his cousin Victoria, thus keeping the British and Hanoverian thrones united, but nothing ever came of that desire and on King William's death, Victoria becomes Queen of the United Kingdom and George becomes 1st in line to the Hanoverian throne and 2nd in line to the British throne (after his father).
