Louis X of France

Louis X (1289–1316), called the Quarrelsome, was the eldest son of Philip IV and Joan I of Navarre, inheriting Navarre in 1305 and ruling France from 1314. His reign saw noble tensions over his father's reforms; he let serfs buy their freedom and readmitted the Jews.

His queen Margaret of Burgundy was convicted of adultery in the 1314 Tour de Nesle affair and died imprisoned, and he then wed Clementia of Hungary. Louis died in 1316 after a game of real tennis, leaving Clementia pregnant. Their posthumous son John I lived only five days, and after a disputed succession Louis's brother became Philip V.
