Sec. to Paris embassy 1749 – 51, minister at The Hague 1751 – 61, ambassador 1761 – 80; P.C. 29 June 1768.
Entering the army, Joseph Yorke received rapid promotion, becoming a lieutenant-colonel before he was of age, and a.-d.-c. to the King, as a result of heavy pressure from his father,1Yorke, Hardwicke, ii. 91-92, 169-71. at 25. Deciding after the peace of Aix-la-Chapelle to exchange a military for a diplomatic career, he was appointed minister to The Hague at the age of 26. Brought into Parliament by the Duke of Dorset2Hardwicke to Newcastle, 1 June 1750, Add. 32721, f. 3. shortly before his appointment, he kept up his membership throughout his 30 years at The Hague, for the prestige which it brought him there, but there is no evidence that he ever attended.
He died 2 Dec. 1792.
