For his entire life, Louis was third in line of succession to the throne behind his father and grandfather. As the grandson of the Dauphin, he was a petit-fils de France. He was styled Duke of Brittany, the first to hold the title since Henry II, nearly 200 years prior. He was placed in the care of the royal governess Louise de Prie.

On 13 April 1705, Louis died of convulsions at the age of nine and a half months. Had he lived, he would have succeeded his great-grandfather as King of France at age eleven.
