House of Bourbon-Parma
The Bourbons of Parma are a royal family who ruled the Duchy of Parma from 1748 till 1860 when Italy was created. The family was founded by the Infante Philip of Spain, third son of Philip V of Spain and Elisabetta Farnese. The Treaty of Aix-la-Chapelle (1748) ended the War of the Austrian Succession, and gave the land to Philip.
Philip married Louise Élisabeth of France and the present pretending duke of Parma (Carlos of Parma) is a direct descendant. The duchy was taken by the House of Savoy when the state of Italy was created.
