Frederick Augustus, Prince, Duke of York and Albany, 1763-1827

Prince Frederick, Duke of York and Albany (Frederick Augustus; 16 August 1763 – 5 January 1827), was the second son of George III, King of the United Kingdom and Hanover, and his consort Charlotte of Mecklenburg-Strelitz. A soldier by profession, from 1764 to 1803 he was Prince-Bishop of Osnabrück in the Holy Roman Empire. From the death of his father in 1820 until his own death in 1827, he was the heir presumptive to his elder brother, George IV, in both the United Kingdom of Great Britain and Ireland and the Kingdom of Hanover. Had he lived three more years, he would have become King of the United Kingdom and Hanover, rather than his younger brother, William IV. Frederick was thrust into the British Army at a very early age and was appointed to high command at the age of thirty, when he was given command of a notoriously ineffectual campaign during the War of the First Coalition, a continental war following the French Revolution. Later, as Commander-in-Chief during the Napoleonic Wars, he oversaw the reorganisation of the British Army, establishing vital structural, administrative and recruiting reforms for which he is credited with having done "more for the army than any one man has done for it in the whole of its history".
