House of Bourbon-Parma in the context of "Grand Duchy of Luxembourg"

The Duchy of Parma and Piacenza (Italian: Ducato di Parma e Piacenza, Latin: Ducatus Parmae et Placentiae) was an Italian state created in 1545 and located in northern Italy, in the current region of Emilia-Romagna.

Originally a realm of the Farnese family after Pope Paul III made it a hereditary duchy for his son, Pier Luigi Farnese, it was ruled by the dynasty until 1731, when the last duke, Antonio Farnese, died without direct heirs. After a decade of Habsburg rule, the duchy passed to the House of Bourbon-Parma.

Infanta Alicia of Spain née Princess Alicia of Bourbon-Parma (Alicia Maria Teresa Francesca Luisa Pia Anna Valeria; 13 November 1917 – 28 March 2017) was a Spanish infanta. A member of the House of Bourbon-Parma, she became Duchess of Calabria through her marriage to Infante Alfonso, Duke of Calabria. She occasionally undertook official duties on behalf of the Spanish monarchy. She was the maternal aunt-in-law of King Juan Carlos I of Spain. She was the longest-lived Infanta 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, Guillaume V, through both the Bourbon-Parma collateral branch of the Spanish royal family and the main branch of Bourbon dynasty.

The House of Luxembourg-Nassau is the current royal house of Luxembourg. It was founded in 1921. It descends from the House of Nassau-Weilburg and from the House of Bourbon-Parma (agnatically), and consists of the extended family of the reigning Grand Duke. There have been three monarchs from the House of Luxembourg-Nassau: Jean, Henri, and Guillaume V.
