The Duke of Kent died quite suddenly in 1820, followed quickly by his father, King George III.
Victoria's uncle, the Prince Regent, ascended the throne as King George IV.
Victoria was now third in line to the throne, after her uncles the Duke of York and the Duke of Clarence, both of whom were well past middle age and neither of whom had legitimate heirs.
As the likely eventual heir, Victoria had to be educated accordingly.
Feodora was now 14, and no longer required the services of a governess.
After the dismissal of nursemaid Mrs. Brock, Lehzen – as she was always known in the household – took over five-year-old Victoria's care in 1824.
The Duchess and her comptroller, John Conroy made the appointment not only because Lehzen was German (rather than English), but also because they believed she was unlikely to operate independently of their wishes.

The historian Christopher Hibbert describes Lehzen as "a handsome woman, despite her pointed nose and chin, clever, emotional, humourless."
Though she at first feared Lehzen's stern manner, "dear, good Lehzen" soon came to occupy a place in Victoria's heart that superseded all others, including her own mother, the Duchess of Kent.
Lehzen encouraged the princess to distrust her mother and her mother's friends, and to maintain her independence.
The governess was uninterested in money and lacked ambition for herself, instead choosing to devote her time and energy to the princess.
Victoria took to calling Lehzen "Mother" and "dearest Daisy" in private, writing Lehzen was "the most affectionate, devoted, attached, and disinterested friend I have."
As part of the controlling Kensington System devised by Conroy, after 1824 Victoria was to be accompanied by Lehzen at all times during the day; consequently Lehzen was not allowed out to leave Victoria's side until the Duchess dismissed her at nighttime, and was required to hold the princess' hand when Victoria descended a staircase.
