Who married Elisabeth of France (1602–1644)?

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, Guillaume V, through both the Bourbon-Parma collateral branch of the Spanish royal family and the main branch of Bourbon dynasty.

Philip IV (Spanish: Felipe Domingo Victor de la Cruz de Austria y Austria, Portuguese: Filipe III; 8 April 1605 – 17 September 1665), also called the Planet King (Spanish: Rey Planeta), was King of Spain from 1621 to his death and (as Philip III) King of Portugal from 1621 to 1640. Philip is remembered for his patronage of the arts, including such artists as Diego Velázquez, and his rule over Spain during the Thirty Years' War.

By the time of his death, the Spanish Empire had reached approximately 12.2 million square kilometres (4.7 million square miles) in area but in other aspects was in decline, a process to which Philip contributed with his inability to achieve successful domestic and military reform. He was succeeded on his death by his young son Charles II as King of Spain and in 1640 (with the collapse of the Iberian Union) by John IV as King of Portugal.
