At the age of nineteen, in the year 1671, Elizabeth Charlotte was married to Philip, Duke of Orleans, only brother of Louis XIV. It was a loveless marriage. Louis XIV. brought about the union for the sake of securing the neutrality of the Prince of the Palatinate in an approaching war between France and Holland. At the time of her marriage Elizabeth was a bright, wholesome, companionable girl. Her husband, a widower of thirty-two, was commonly suspected of being at least accessory to the poisoning of his first wife, Henrietta, a sister of Charles II. of England. In the correspondence of Elizabeth and her aunt, the Duke of Orleans is always referred to as "Monsieur."

Elizabeth's ideal of manhood was the older German ideal, an honest, fearless man, an enthusiastic hunter, a skilful horseman, a sturdy drinker, and, withal, a stout-handed Christian, ready at a moment's notice to knock down an old church and build a new one on its site, or, if his faith lay the other way, to fight to the last ditch for the old church against the new. Therefore, there must have been bitterness at the young wife's heart when she penned the following very accurate description of her bridegroom:

"Monsieur has extremely ladylike manners. He cares for nothing so rude as horses and hunting. He cares for nothing, in fact, except the Court receptions, for dainty eating, dancing, and fine toilettes. In short, his tastes are all effeminate."

She gives an equally merciless picture of herself: "I must be very ugly. I have little eyes, a short, thick nose, and a flat, broad face. I am little and thickset. Naturally, I hate mirrors and never injure my self-esteem by looking into one if I can help it." Though Elizabeth was not beautiful, she must have possessed the charm of a thoroughly honest, humorous, and impulsively kind nature. Her boy-cousins and young friends in Germany called her "Comrade" and "Bub." Louis XIV. was very fond of his German sister-in-law. She walked, rode, and hunted with him frequently. Except when he persecuted Germany, she liked the king extremely well.

Although no love existed at any time between the Duke of Orleans and his wife, one point, remarkable in that universally loose age, must be noted. They were true to each other. She writes in later years: "I never had any reason to complain of Monsieur in respect to his behavior so far as other women were concerned." She had no "love affair" in all the years she lived with him. A cabal, seeking to fasten scandal upon her in connection with the Chevalier Sincsanct, utterly failed to produce proof against her, or even to cast public suspicion upon her. She had three children, two boys and a girl. The oldest boy died at the age of three years. The struggle of Elizabeth's life was to preserve her two remaining children from the impure influences around them, and it was a long and bitter fight. Her daughter she saved. Her son, afterward Regent of France during the long minority of Louis XV., owed all that was good in him and that was much, in spite of his excesses to the prayers, the love, the admonitions of his mother. In her efforts to train the children rightly Elizabeth was constantly thwarted by her husband. Philip was entirely controlled by two bad men, the Chevalier de Lorraine and the Marquis d'Essiat. Both hated Elizabeth because of her moral influence over the king. By her efforts, many of their iniquitous plots against women were frustrated. The only way they could punish her was through her children. Madame de Maintenon, whom Elizabeth treated disdainfully, was believed by the duchess to have been an accomplice in the plan to remove her children from her influence.

Madame de Maintenon loved the children of the king's former mistress, Montespan, as if they were her own. Two of these children, Mademoiselle de Blois and the Duke of Maine, were still unmarried. It was now proposed, ostensibly by the king, that Elizabeth's son, the Duke of Chartres, should marry Mademoiselle de Blois. Also, it was planned, that her daughter Charlotte should at the same time become the wife of the young Duke of Maine. Elizabeth was furious. She refused her consent. Saint-Simon, in his Memoirs, says of her at this time:

"She belongs to a nation which abhors bastards and mesalliances. Moreover, she has a determined character which forbids all hope that she may ever consent."

The Duke of Chartres a boy of eighteen promised his mother to refuse to contract the alliance. Then, the Abbé Dubois, who had great influence over him, secured a contrary promise. When the king himself urged the duke to marry Mademoiselle de Blois, the youth became confused and said he would leave the decision to his parents. Whereupon, his father, without more ado, had the engagement announced that evening at the court dinner. Elizabeth wept throughout the meal. Louis XIV., it is said, made awkward attempts at consolation by passing her the choicest dishes. At the circle which followed, her son came up to kiss her hand. The memory of his broken promise was fresh in her mind. To the astonishment of the polished French court, she boxed the boy's ears soundly. An awful silence followed this impulsive piece of maternal discipline. The young duke, scarlet with mortification, stood abashed. His poor little pale bride-elect grew whiter than ever; Elizabeth, hardly making a reverence to the king, left the room. The people of Paris sided with the duchess. They threatened the life of Madame de Maintenon if the other proposed marriage, between Elizabeth's daughter and the Duke of Maine, was insisted upon. "I am very grateful to my friends, the Parisian mob," Elizabeth writes to her aunt.

From this time the breach between Elizabeth and her husband was complete. She was also estranged from her son. Her daughter was kept at a long distance from her amidst the most corrupt surroundings. Elizabeth became very lonely. The king, because of her opposition to the seizure of the Palatinate, now ignored her. Her husband seldom spoke to her. Her daughter was away but had been happily married. Her son, at this time, was very dissolute and avoided meeting her. She writes:

"Here in this great court I live, a hermit. Day after day I spend alone in my library. If visitors come I see them a few minutes, speak of the weather or the newspaper, then back again to my solitude."
