During these festivities the king had shown marked courtesy to the Admiral and the Huguenot lords, and it seemed as if he had again emancipated himself from his mother's influence; and the hopes of the Protestants, that he would shortly declare war with Spain, were raised to the highest point.
Although the question was greatly debated at the time, and the belief that the massacre of the Protestants was deliberately planned long beforehand by the king and queen-mother is still generally entertained, the balance of evidence is strongly the other way.

What dark thoughts may have passed through the scheming brain of Catharine de Medici none can say, but it would certainly appear that it was not until after the marriage of Henri and Marguerite that they took form.

She saw that, in the event of a war with Spain, the Huguenots would become all powerful in France.

Already the influence of the Admiral was greater than her own, and it had become a battle of life and death with her; for Coligny, in his fearless desire to do what was right, and for the service of France, was imprudent enough over and over again to warn the king against the evil influence of the queen mother and the Duke d'Anjou; and Charles, in his fits of temper, did not hesitate to divulge these counsels.
