Caroline Matilda of Great Britain (22 July 1751 – 10 May 1775) was by birth a Princess of Great Britain and member of the House of Hanover and by marriage Queen consort of Denmark and Norway from 1766 to 1772.
The youngest and posthumous daughter of Frederick, Prince of Wales, by Princess Augusta of Saxe-Gotha
, Caroline Matilda was raised in a secluded family atmosphere away from the royal court.
At the age of fifteen, she was married to her first cousin, King Christian VII of Denmark and Norway, who suffered from a mental illness and was cold to his wife throughout the marriage.
She had two children: the future Frederick VI and Louise Augusta, whose biological father may have been the German physician Johann Friedrich Struensee.
In 1769, Struensee entered the service of the Danish king; initially Caroline Matilda treated him coldly, but he quickly won the Queen's heart and they began a love affair.
Struensee gained more and more power and instituted a series of reforms that Caroline Matilda supported.
Struensee's reforms and his relationship with the Queen generated powerful enemies, who included Christian VII's stepmother Queen Dowager Juliana Maria and her son Prince Frederick.
Juliana Maria directed a plot to overthrow the lovers, which ended with the execution of Struensee and Caroline Matilda's divorce and banishment.
She died in Celle, Hanover, at the age of twenty-three from scarlet fever.
