"William Cavendish, 1st Duke of Newcastle upon Tyne, KG, KB, PC (c. 16 December 1593 – 25 December 1676) was an English courtier and supporter of the arts. He was a renowned horse breeder, as well as being patron of the playwright Ben Jonson, and the intellectual group known as the Welbeck Circle.
Despite spending the then enormous sum of £15,000 entertaining Charles I in 1634, he failed to gain a significant political post. In the early stages of the First English Civil War, he was appointed Royalist Captain-General in Northern England; he financed much of the war effort himself, later claiming this totalled in excess of £1,000,000. After the defeat at Marston Moor in July 1644, a battle fought against his advice, he went into exile in Europe." - (en.wikipedia.org 28.05.2022)
