Queen Elizabeth II has died at the age of 96 at Balmoral Castle, her estate in the Scottish Highland, in the United Kingdom.
The Queen died peacefully on Thursday afternoon, Buckingham Palace said in a statement.
With her death, her eldest son Charles will become the new King.
The Queen, who had reigned for 70 years, was placed under medical supervision on Thursday Sep. 8, with doctors being “concerned” about her health, the palace said in a statement.
Her health had appeared to deteriorate rapidly on Thursday, as she canceled a virtual meeting with members of her Privy Council on Wednesday meeting after doctors advised her to rest, according to the New York Times.
Members of the royal family, including the Queen’s children, Prince Charles, and his wife Camilla, and Princess Anne, rushed to her side on Thursday.
Her grandson, Prince William, who is second in line to the throne, had also traveled to Balmoral, as well as his brother, Prince Harry.
The Queen had just appointed Liz Truss as the new UK prime minister on Tuesday.
“The King and the Queen Consort will remain at Balmoral this evening and will return to London tomorrow,” the palace said.
