June 20, 1837
The new heir presumptive to the throne, the Duke of Cumberland, now the King of Hanover, spent last night at Windsor Castle, and returned to his apartments at St. James's Palace at 8 o'clock. The Duke of Cumberland was also the first person to take "the oath of allegiance" to the new Queen, who is only 18 years old.
Her Royal Highness Princess Augusta, "despatched a page express from the palace at 11 o'clock to Windsor, to inquire into the state of the Queen Dowager."
A note was placed on the door of the New National Gallery at Trafalgar Square: "In consequence of the lamented demise of the King, the Exhibition will remain closed until further notice." Theatres and other public amusements were also ordered to be closed.
