Elisabeth of France, Queen of Spain

Elisabeth of France, also known as Isabel or Elisabeth of Bourbon (22 November 1602 – 6 October 1644) was Queen of Spain from 1621 to her death and Queen of Portugal from 1621 to 1640, as the first spouse of King Philip IV & III. She served as regent of Spain during the Catalan Revolt in 1640–42 and 1643–44. As the mother of the Queen of France Maria Theresa, wife of Louis XIV, she was the great-grandmother of the Duke of Anjou, who became king of Spain as Philip V. Through her daughter, Elisabeth is the progenitor of the Spanish branch of the House of Bourbon, which still rules over Spain to this day, as all future kings of Spain after the War of Spanish Succession descend from her. She's also the ancestor of the current Grand Duke of Luxembourg, Henri, through both the Bourbon-Parma collateral branch of the Spanish royal family and the main branch of Bourbon dynasty, as he is a descendant of the last Duke of Parma, Robert I, and his mother Louise of Artois, the granddaughter of Charles X of France, through Robert's son Felix.
