King of Spain (Anglicised name: Louis I) from 15 January 1724 until his death in August the same year. His reign is one of the shortest in history, lasting for just over seven months.
The eldest son of the reigning King Philip V of Spain and his wife Maria Luisa of Savoy, he was the heir apparent at birth but was not given the traditional title of “Prince of Asturias” until April 1709. In 1714, when Louis was seven, his mother died, leaving him and his two brothers.
As heir not only to the vast Spanish empire, but also to a new dynasty, it was decided that Louis would take a wife as soon as possible. On 20 January 1722, at Lerma, he met and married Louise Élisabeth d’Orléans, a daughter of Philippe d’Orléans, Duke of Orléans, cousin of Louis’ father and then the Regent of France. She did not fit into the religious Spanish Court well and she often refused to speak to her husband. There were no children of the marriage and Louise Élisabeth refused to even see her husband.
Louis ruled for a short period between the time his father Philip V abdicated in his favour (14 January 1724) and his death from smallpox, just over seven months later on 31 August 1724. On his death, his father returned to the throne, and reigned until his own death in 1746.
