Mourners have flocked to the gates of Buckingham Palace to honor Queen Elizabeth II as the country prepares for a new age under a new king.

King Charles III planned to meet Friday with the prime minister and address a nation grieving the only British monarch most of the world had known. He takes the throne in an era of uncertainty for both his country and the monarchy itself.

As the United Kingdom began a 10-day mourning period, people worldwide gathered at British embassies to pay homage to the queen. She died Thursday at 96.

In Britain and its former colonies, the admiration for Elizabeth was occasionally mixed with scorn for the institution and the imperial history she represented.
