Jean du Tillet, sieur de La Bussière

Jean du Tillet also began compiling a dossier meant to justify a break with Rome if such occurred, but Henry II reconciled with the papacy in 1552.

Following Henry's death in 1559, and in spite of the support of Anne de Montmorency, du Tillet was forbidden to publish his findings by Charles, Cardinal of Lorraine.

Instead, he was paid to write against the Amboise conspirators, led by his personal enemy, Jean du Barry [fr].

[1] Although Francis II ordered du Tillet to bring organization to the royal archives, he seems to have been too busy using them to have advanced far in that task.

In these short works—Pour la majorité du roi treschrestien contre les escrits des rebelles and Pour l'entiere majorité du roi treschrestien contre le legitime conseil malicieusement inventé par les rebelles—he argued that Roman law did not control the French monarchy, which was based on customary law.

[2] Jean du Tillet's most famous work is Recueil des rois de France [fr], which was first published posthumously by his nephew in 1577, having first been suppressed by the cardinal of Lorraine.
