At this period Marguerite de Valois began to divide her existence between the most exaggerated devotional observances and the most sensual and degrading pleasures.  Humbly kneeling before the altar, she would assist at several masses during the day; but at twilight she cast off every restraint, and careless of what was due, alike to her sex and to her rank, she plunged into the grossest dissipation; and after having played the guest at a riotous banquet, she might be seen sharing in the disgraceful orgies of a masquerade.[4] A short time after the marriage of the Duc de Guise, the hand of the Princess was demanded by Don Sebastian, King of Portugal; but the Queen-mother, who witnessed with alarm the increasing power of the Protestant party, and the utter impossibility of inspiring confidence in their leaders save by some bold and subtle stroke of policy, resolved to profit by the presence of the Huguenot King of Navarre, in order to overcome the distrust which not even the edict of 1570 had sufficed to remove; and to renew the project which had been already mooted during the lifetime of Jeanne d’Albret, of giving Marguerite in marriage to the young Prince, her son.

The consciousness that she was sacrificing her daughter by thus bestowing her hand upon the sovereign of a petty kingdom might perhaps have deterred Catherine, had she not already decided upon the means by which the bonds of so unequal an alliance might be rent assunder; and it is even possible that the hatred which she bore to the reformed faith would in itself have sufficed to render such an union impossible, had not the crafty and compunctionless spirit by which she was animated inspired her with a method which would more than expiate the temporary sin.  It is at all events certain that having summoned Henry of Navarre to her presence, she unhesitatingly, and with many professions of regard for himself, informed him of the overtures of the Portuguese monarch, assuring him at the same time, that although the King of Spain was opposed to the alliance from motives of personal interest, it was one which would prove highly gratifying to Gregory xiii; but adding that both Charles IX and herself were so anxious to perform the promise which they had made to his mother, and to prove their good faith to his own person, that they were willing to refuse the crown of Portugal and to accept that of Navarre for the Princess.

Henry of Bearn hesitated.  He was aware that the chiefs of the Protestant party, especially the Admiral de Coligny, whom he regarded as a father, were desirous that he should become the husband of Elizabeth of England.  Past experience had rendered them suspicious of the French, while an alliance with the English promised them a strong and abiding protection.  Nor was Henry himself more disposed to espouse Marguerite de Valois, as her early reputation for gallantry offended his sense of self-respect, while a strong attachment elsewhere rendered him insensible to her personal
