The king appointed, as his preachers, four of the most violent advocates of persecution.

The De Montmorencys, for a time, struggled successfully against the influence of the Cardinal of Lorraine; who sought supreme power, under cover of Henry of Anjou's name.

Three of the marshals of France--Montmorency, his brother Danville, and Vielleville--supported by Cardinal Bourbon, demanded of the council that D'Anjou should no longer hold the office of lieutenant general.

Catharine at times aided the Guises, at times the Montmorencys; playing off one party against the other, but chiefly inclining to the Guises, who gradually obtained such an ascendency that the Chancellor L'Hopital, in despair, retired from the council; and thus removed the greatest obstacle to the schemes and ambition of the Cardinal of Lorraine.
At the commencement of August the king despatched, to all parts of his dominions, copies of an oath that was to be demanded from every Huguenot.

It called upon them to swear never to take up arms, save by the express command of the king; nor to assist with counsel, money, or food any who did so; and to join their fellow citizens in the defence of their towns against those who disobeyed this mandate.
