Princess Charlotte was born at 08:34 BST on 2 May 2015 in St Mary's Hospital, London, during the reign of her paternal great-grandmother, Queen Elizabeth II, as the second child of Prince William and Catherine, then known as Duke and Duchess of Cambridge.

[5][6] Charlotte was christened on 5 July by the archbishop of Canterbury, Justin Welby, at St Mary Magdalene Church, Sandringham.

[11] In 2022 the family relocated to Adelaide Cottage in Windsor Home Park,[12] after which she and her brothers, George and Louis, began attending Lambrook, an independent preparatory school in Berkshire.

[21] Shopping statistics and polls among parents show that Charlotte is a major children's style icon.

[27][28] Because of the implementation of the Perth Agreement, which replaced male-preference primogeniture with absolute primogeniture, she did not move down the line of succession upon the birth of her younger brother Louis in April 2018, making her the first British princess in history to rank above a brother in the line of succession.
