Filippo I, Duke of Parma

Philip was Duke of Parma from 18 October 1748 until his death in 1765. A Spanish infante by birth, he was born in Madrid as the second son of King Philip V and Queen Elisabeth. He became Duke of Parma as a result of the 1748 Treaty of Aix-la-Chapelle. The duchy had earlier been ruled by Philip's elder brother, the future Charles III of Spain, and by their maternal ancestors. Philip founded the House of Bourbon-Parma, a cadet line of the House of Bourbon. He was a first cousin and son-in-law of the French king Louis XV.
