, 1641 By the end of the 1630s, relations between the various factions in English society had become very tense; controversies over religion, social relations, morality, and political power became more and more heated. At the same time, Mary's mother, who openly professed Catholicism, became more and more unpopular in the country. In late 1640–early 1641, King Charles I decided to renew negotiations with Prince Frederick Henry of Orange. The negotiations progressed quickly. On 10 February 1641, Charles announced to
Parliament that the betrothal of his daughter was actually concluded and that it only remained to consider this union from a political point of view. Charles himself hoped that in case of emergency, the Prince of Orange would help him to maintain royal power in England. A modest wedding ceremony took place on 2 May 1641 at the
Chapel Royal in
Whitehall Palace,
London. Queen Henrietta Maria was unable to attend the religious ceremony as it was a Protestant one; instead, she watched her daughter's wedding from a small gallery. The marriage of the King's eldest daughter was practically not celebrated in England, as the country was on the verge of a war that broke out in less than a year. The King gave her a crystal and gold casting bottle garnished with rubies and diamonds and a gold chain with the cipher "AR" which had belonged to
Anne of Denmark. Mary and William were congratulated by courtiers, and received several gifts; in addition, in honour of the newlyweds, a volley of 120 guns was fired. After the ceremony, William returned to the Netherlands. According to the marriage contract, Mary could remain in England until she was 12 years old, and her husband would provide her with 1,500
livres per year for personal expenses. In addition, in the event of the untimely death of William, Mary would receive a maintenance of 10,000 livres per year and two residences for her personal use. The marriage contract also provided that Mary and her English attendants could still worship in the manner of the
Church of England, rather than join the
Dutch Reformed Church. In early 1642, the situation in the country heated up. Mary and her parents were forced to take refuge in Hampton Court, but the situation steadily turned into open war. In February, Queen Henrietta Maria departed with her daughter to
The Hague in the Netherlands; they travelled on a Dutch fleet of fifteen ships. Mary was accompanied to the Netherlands by her governess,
Lady Stanhope, who later became her confidant and companion. From a political point of view, the marriage of Mary partially paid off in 1643, when Henrietta Maria persuaded the Dutch government to provide a ship and arms for Charles, and sent them to England. by
Gerard van Honthorst, 1647 Shortly before leaving for the Netherlands, Mary was designated by her father
Princess Royal, thus establishing the tradition that the eldest daughter of the British sovereign might bear this title. The title was created because Queen Henrietta Maria, the daughter of King
Henry IV of France, wanted her daughter to have a title comparable to "
Madame Royale", the style of the eldest daughter of the king of France. Until that time, the eldest daughters of English and Scottish kings were variously titled
lady or
princess. The younger daughters of British sovereigns were not consistently titled princesses of Great Britain and styled "Royal Highness" until the accession of
George I in 1714. In November 1643, the second marriage ceremony between the 12-year-old Mary and 17-year-old William took place in The Hague. The marriage was not consummated until 1644. In February 1644, Mary completely merged into the life of the Dutch court. She gave audiences, met with foreign ambassadors, and performed all the functions assigned to her with an importance and dignity considered astonishing for her age. In March, she participated in court celebrations of the recent alliance between
France and the Netherlands, and led the entertainment that her husband arranged for the French ambassador. Mary, who was constantly receiving news from England, sympathized with her father Charles' cause. In December 1646, she sent him a letter (via a Dutch merchant ship) urging him to flee to the Netherlands, but Charles declined. In The Hague, Mary developed a very warm relationship with her aunt,
Elizabeth, the exiled former Queen of Bohemia. However, Mary didn't develop a good relationship with her mother-in-law Amalia, so she tried to minimize contact with her. Prince Frederick Henry of Orange died on 14 March 1647. On the day of his death, the
States General of the Netherlands was convened, which proclaimed William II to be his father's heir as stadtholder and head of the army; one by one, the remaining titles of her late father-in-law were recognized for Mary's husband, and he became the new
prince of Orange. In 1648, Mary was visited by her brothers,
Charles, Prince of Wales, and
James, Duke of York. In 1649, Mary's father
King Charles was executed; subsequently, Mary helped many English Royalist exiles. Among those who were under her patronage was the family of
Anne Hyde – the future wife of the Duke of York and mother of two English Queens,
Mary II and
Anne. ==Co-regency==
