Princess Amelia (7 August 1783 – 2 November 1810) was the fifteenth and last child and sixth daughter of King George III the United Kingdom and his wife, Charlotte of Mecklenburg-Strelitz.

[6] When Amelia was only a month old, Princess Charlotte wrote to her brother William, "Our littlest sister is without exception one of the prettiest children I have ever seen".

As the youngest of the thirteen surviving children, Amelia spent most of her time with her sisters Mary and Sophia, living in various royal residences.

From the beginning, the three younger princesses did not receive as much parental attention as their elder sisters had, and spent a good deal of time away from the King and Queen, communicating with them mostly by letter.

As a consequence of her father's declining health, she never experienced the closeness and affection that had characterized the family during her elder sisters' early years.

[11] Prior to 1788, King George had told his daughters that he would take them to Hanover and find them suitable husbands[12] despite misgivings he had, which stemmed from his sisters' own unhappy marriages.

The question of matrimony was rarely raised; Queen Charlotte feared that the subject, which had always discomfited the King, would push him back into insanity.

"[16][17] The following year, Amelia temporarily recovered enough to join her family at Weymouth, where she doted upon her 3 year-old niece Princess Charlotte of Wales.

It was hoped that such discretion would prevent the King from discovering the liaison, which may have risked sending him into one of the bouts of mental illness to which he was becoming increasingly prone.

This improvement was temporary, and in August 1810 her sufferings grew sharper, while in October of that year she was seized with St. Anthony's fire (erysipelas), which cut off all hope and confined her to her bed on the 25th.

[22] The dying princess had a mourning ring made for the King, composed of a lock of her hair under crystal set round with diamonds.

Her death is credited with contributing to the decline in her father's health which resulted in his insanity[24][26][27] and the subsequent invocation of the Regency Act 1811.

[citation needed] According to his physician, Dr. Willis, the king would later cry "in a wild, monotonous, delirious way, 'Oh Emily [Princess Amelia], why won't you save your father?

I hate all the physicians..."[28] Another of King George's delusions included the belief that a healthy Amelia was only staying in Hanover with a large family of her own, where she would "never grow older and always be well.
