Louis' uncle—Charles of Valois, leader of the feudalist party—managed to convince the king to execute Enguerrand de Marigny.
Louis allowed serfs to buy their freedom (which was the first step towards the abolition of serfdom), abolished slavery, and readmitted French Jews into the kingdom.

In 1315, Louis married Clementia of Hungary, who gave birth to John I of France a few months after the king's death.
