Louis, Dauphin of France, commonly known as le Grand Dauphin, was the eldest son and heir apparent of King Louis XIV and his spouse, Maria Theresa of Spain. He became known as the Grand Dauphin after the birth of his own son, Louis, Duke of Burgundy, the Petit Dauphin. He and his son died before his father and thus never became kings. Instead, his grandson became King Louis XV at the death of Louis XIV, and his second son inherited the Spanish throne as Philip V through his grandmother.

Maria Theresa of Spain was Queen of France from 1660 to 1683 as the wife of King Louis XIV. She was born an Infanta of Spain and Portugal as the daughter of King Philip IV and Elisabeth of France, and was also an Archduchess of Austria as a member of the Spanish branch of the House of Habsburg.
