In August, 1561, Mary left France with tears, and was received in Scotland with every mark of respect. She came, alone and unprotected, to assume the government of a country which had long been distinguished for its rebellious turbulence. Contrasted, too, with her former situation, that which she was now about to fill appeared particularly formidable. By whatever counsel she acted, the blame of all unpopular measures would be sure to rest with her. If she favored the Protestants, the Catholics were sure to renounce her, and if she assisted the Catholics, the Protestants would be again found assembling at Perth, listening, with arms in their hands, to the sermons of John Knox, pulling down the remaining monasteries, and subscribing additional covenants. Is it surprising, then, that she found it difficult to steer her course between the rocks of Scylla and the whirlpools of Charybdis? If misfortunes ultimately overtook her, the wonder unquestionably ought to be, not that they ever arrived, but that they should have been guarded against so long.

To further their political views, Mary's hand was sought for by princes of the several European courts. The princes of the house of Austria, apprehensive of the ambition of France, wished a union between the Scottish queen and the Archduke Charles. Philip II., envying the Austrians so important a prize, used all his influence to procure her hand for his son Don Carlos, heir to the extensive domains of the Spanish monarchy. Catharine de Medicis, jealous of them both, offered the hand of the Duke of Anjou, brother to her former husband, and Elizabeth, the artful queen of England, recommended Lord Robert Dudley, afterward Earl of Leicester.

Mary shunned all their intrigues, and followed the bent of her own inclination in marrying Henry Stuart, Lord Darnley, eldest son of the Earl of Lennox. Darnley, at this time in the bloom of youth, was distinguished for the beauty and grace of his person, and accomplished in every elegant art; and he also professed the Catholic religion. Darnley's qualifications, however, were superficial, and abandoning himself to pleasure and the vices of youth, he became gradually careless and indifferent toward the queen, whose disappointments and mortifications were in proportion to the fervor of her former sentiments. Her French secretary was one David Rizzio, who was possessed of musical talents, and to whom she became much attached. Darnley became jealous of Rizzio, and he, with a number of conspirators, took possession of the palace on March 9, 1566, while the queen was at supper with the Countess of Argyle and Rizzio. The latter clung to the queen for protection, but he was torn from her and dragged to the next apartment, where the fury of his enemies put an end to his existence, by piercing his body with fifty-six wounds. The conspirators put Mary under guard, but she escaped, and by the aid of Bothwell and others, she was soon enabled to put her enemies at defiance. This event served to alienate Mary's affections from Darnley.

On June 19, 1566, the queen gave birth to a son; an event more fortunate to the nation than to his unhappy mother, whose evil destiny received aggravation from a circumstance which appeared so flattering to her hopes.

Darnley, neglected by the queen, and despised by the people, remained in solitude at Stirling, but alarmed by the rumor of a design to seize his person, he thought fit to retire to his father at Glasgow. On his way thither he was seized with a dangerous illness. Mary visited him, and it is said prevailed on him to be removed to the capital, where she would attend on him. Kirk of Field, a house belonging to the provost of a collegiate church, was prepared for his reception. The situation, on a rising ground and in an open field, was recommended for the salubrity of its air.

At two o'clock on the morning of February 10, 1567, the city was alarmed by a sudden explosion. The house in which Darnley resided was blown up with gunpowder. The dead body of Henry and a servant, who slept in his room, were found lying in an adjacent garden, without marks of violence, and untouched by fire. Thus perished Henry Stuart, Lord Darnley, in his twenty-first year, a youth whom the indulgence of nature and fortune had combined to betray to his ruin.

This execrable deed gave rise to various suspicions and conjectures, which, while they glanced at the queen from her new sentiments with regard to her husband, were, with a general consent, directed toward Bothwell. A proclamation was issued from the throne, offering a considerable reward for the murderer. Neither the power and greatness of Bothwell, nor his favor with the queen, secured him from the indignant sentiment of the nation. He had a mock trial, in which he was acquitted.

The queen, on a journey from Edinburgh to Stirling, to visit her son, was seized by a party of Bothwell's and conducted a prisoner to his castle at Dunbar. Here he prevailed on her to marry him, and on her subsequent appearance in public she was received with a sullen and disrespectful silence by the people.

The transactions which had passed during the last three months in Scotland were beheld by Europe with horror and detestation. The murder of the king, the impunity with which his assassins were suffered to escape, and the marriage of the queen with the man accused of being their chief, were a series of incidents, which, for their atrocity and rapid succession, were scarcely to be paralleled in the pages of history. A general infamy fell upon the Scotch nation, which was regarded, from these circumstances, as a people void of decency, humanity, and honor.
