Francis I. did not allow the magnificent reception accorded to him at Alençon to pass unrewarded. He presented his sister with the duchy of Berry, where she henceforward exercised temporal control, though she does not appear to have ever resided there for any length of time. In 1521, when her husband started to the relief of Chevalier Bayard, attacked in Mézières by the Imperial troops, she repaired to Meaux with her mother so as to be near to the Duke. Whilst sojourning there she improved her acquaintance with the Bishop, William Briçonnet, who had gathered around him Gerard Roussel, Michael d’Arande, Lefèvre d’Etaples, and other celebrated disciples of the Reformation. The effect of Luther’s preaching had scarcely reached France before Margaret had begun to manifest great interest in the movement, and had engaged in a long correspondence with Briçonnet, which is still extant. Historians are at variance as to whether Margaret ever really contemplated a change of religion, or whether the protection she extended to the Reformers was simply dictated by a natural feeling of compassion and a horror of persecution. It has been contended that she really meditated a change of faith, and even attempted to convert her mother and brother; and this view is borne out by some passages in the letters which she wrote to Bishop Briçonnet after spending the winter of 1521 at Meaux. Whilst she was sojourning there, her husband, having contributed to the relief of Mézières, joined the King, who was then encamped at Fervacques on the Somme, and preparing to invade Hainault. It was at this juncture that Clement Marot, the poet, who, after being attached to the person of Anne of Brittany, had become a hanger-on at the Court of Francis I., applied to Margaret to take him into her service.

Shortly afterwards we find him furnishing her with information respecting the royal army, which had entered Hainault and was fighting there.
