Sophia was 27 years of age, and had already become the Queen in Prussia and a mother of many children by the time her father became King George I of Great Britain in 1714.

[4] Sophia Dorothea married her cousin (her father's sister's son), Crown Prince Frederick William of Prussia, heir apparent to the Prussian throne, on 28 November 1706.

[4] When a marriage was to be arranged for Frederick William, he was given two alternatives: Princess Ulrika Eleonora of Sweden or Sophia Dorothea of Hanover.

Though not regarded as strictly beautiful, she was seen as quite attractive at the time of her marriage and described as charming in her manners, making a good impression in Berlin.

Sophia Dorothea was interested in art, science, literature and fashion, while Frederick William was described as an unpolished, uneducated and spartan military man with rough manners.

"[4] The birth of her firstborn son, Frederick Louis, in 1707 was celebrated greatly in Prussia, and Sophia Dorothea successfully asked the king to liberate the imprisoned minister Eberhard von Danckelmann.

At the time of the accession, Prussia was at war with Sweden, and Sophia Dorothea accompanied Frederick William during the campaign of 1715, though she soon returned to Berlin to give birth to her daughter.

Sophia Dorothea's first favorite was her maid of honor, von Wagnitz, who was dismissed after an intrigue in which Kreutz[clarification needed] and her mother tried to make her the king's mistress, as well as being a spy of the French ambassador Rothenburg.

[4] Queen Sophia Dorothea was admired for her gracious manners and nicknamed "Olympia" for her regal bearing, but scarred by smallpox and overweight with time, she was not called a beauty.

She was known as extremely haughty, proud, and ambitious, but Frederick William greatly disliked her interference in politics, as it was his belief that women should be kept only for breeding, and kept submissive as they would otherwise dominate their husbands.

[4] Frederick William viewed her interests in theater, dancing, jewelry and music as frivolous and resented any sign of her living a life independently from his authority: he particularly disliked her interest in gambling, and it is reported that she and her partners would have coffee beans ready on the table during gambling, so that if the king appeared, they could pretend to be playing with them rather than money.

[6] On one occasion, the queen took the opportunity of the king being ill to host a ball at Monbijou with dancing and music, and where she herself gambled while wearing her diamond set.

[4] Within the document, she was named regent during the minority of their son, with Charles VI, Holy Roman Emperor, and King George I of Great Britain as guardians to the crown prince.

Sophia Dorothea had a very close relationship to her eldest son, Crown Prince Frederick, who was harshly treated by his father, who perceived him as effeminate.

[6][4] At the same time, the queen's favorite, Madame de Ramen, acted as a spy for the king, causing their relationship to deteriorate sharply.

In October of that year, they hosted a visit by George I in Berlin, who inspected Wilhelmine and agreed to the double marriage alliance if it was approved by Parliament.

Upon his return, he had to be prevented from beating her by her chief lady-in-waiting, Sophie von Kameke, who held his arm and told him "if he had only come there to kill his wife, he had better have kept away.

Sophia Dorothea accompanied Frederick William to meet George in Hanover to discuss the matter, and was left there to handle the negotiations when he returned to Berlin.

[4] Frederick, Prince of Wales, sent his agent Lamotte to ask whether she would permit a secret visit by him to see his intended bride, Wilhelmine.

[4] The animosity between the queen and Seckendorff was well known and commented on by the king: In 1729, negotiations for the British marriage alliance were disrupted by the activities of Frederick William's army recruiters.

[4] Sophia Dorothea spent many days talking to her eldest son in the library, and was informed of his plans to escape from his father's custody.

[4] Her decision was made against the will of her mother, who threatened to disown her for what she considered to be her daughter's lack of courage, and ordered her not to speak to her future groom when he arrived.

[4] When Frederick was liberated after his sister's wedding, Sophia Dorothea resumed negotiations with Great Britain to marry him to Princess Amelia, and her next daughter, Philippine Charlotte, to the Prince of Wales, which would complete her life project of a Prussian-British marriage alliance.

She openly declared her view when the king swore loyalty to Austria: "I shall live to make you, who are so incredulous, believe, and prove to you how you are deceived.

"[4] During the last years of the king's life, he was afflicted with fits of illness which often forced him to use a wheelchair, and Sophia Dorothea was ordered to attend to him continuously.

She seldom left his room for months before his death, save to follow him in his wheelchair; she bore with his impatience, soothed his suffering, and hers was the hand which, to the last, best smoothed the pillow, and administered the potion.

[4] On the day of his death, Frederick William ordered himself to be taken to the queen's apartment and told her: "Rise, I have but a few hours to live, and I would at least have the satisfaction of dying in your arms.

The loss of a husband, who, despite his frequent harsh treatment, had been sincerely attached to her, and who was endeared by the habitual intercourse of many years, deeply affected Sophia Dorothea.

When the Marchioness of Bayreuth revisited Berlin, she found her mother clad in deep mourning, and with an air of profound dejection impressed upon her features.

When she addressed him as "Your Majesty" after the funeral of his father, he interrupted her and told her: "Always call me your son, that title is dearer to me than the royal dignity.
