Queen Elizabeth was buried with her husband, Prince Philip.
Britain's Queen Elizabeth II "died peacefully" on Thursday, Sept. 8, at Balmoral Castle, the British royal family's estate in Aberdeenshire, Scotland, according to a statement from Buckingham Palace. She was 96.
Elizabeth was Britain's longest-reigning monarch. She ascended to the throne in 1952 and, in June, celebrated her Platinum Jubilee, marking 70 years as queen.
The order of service has been released for Queen Elizabeth II's state funeral Monday, including who will walk in the procession behind the queen's coffin.
According to the order, Prince George and Princess Charlotte are expected to walk behind their parents, William, Prince of Wales, and Catherine, Princess of Wales, respectively.
"Over the last ten days, my wife and I have been so deeply touched by the many messages of condolence and support we have received from this country and across the world," King Charles said in the written message issued by Buckingham Palace on Sunday.
"In London, Edinburgh, Hillsborough and Cardiff we were moved beyond measure by everyone who took the trouble to come and pay their respects to the lifelong service of my dear mother, The late Queen," he said. "As we all prepare to say our last farewell, I wanted simply to take this opportunity to say thank you to all those countless people who have been such a support and comfort to my Family and myself in this time of grief."

The White House shared two images showing what President Joe Biden and first lady Jill Biden wrote in the condolence books for Queen Elizabeth II.
In the handwritten notes the Bidens expressed their fondness for the queen and praised her commitment to service.
“Queen Elizabeth was admired around the world for her unswerving commitment to service," President Biden wrote. "She hosted everything with dignity and respect. Jill and I were honored to have met with her and feel her warmth. Our hearts go out to the Royal Family and the people of the United Kingdom.”
In a separate condolence book, Jill Biden, wrote, “Queen Elizabeth II lived her life for the people she served with wisdom and grace. We will never forget her warmth, kindness, and the conversations we shared. May God grant her eternal rest."
President Joe Biden and first lady Jill Biden paid their respects to Queen Elizabeth II on Sunday, visiting her body lying in state at Westminster Hall.
The Bidens appeared on a balcony overlooking the queen's coffin. President Biden made a sign of the cross and put his hand over his heart while he and his wife observed the coffin for about two minutes.
Jill Biden also signed a book of condolence in the Drawing Room of Lancaster House in London as her husband looked on. President Biden signed a separate book of condolences in the State Dining Room of Lancaster House.
“Our hearts go out to the royal family, King Charles and all the family," Biden said after signing the book of condolences.
He fondly recalled one of his meetings with the queen.
"When the Queen had us to the castle for tea -- and me joking krimpets, she kept offering me more. I kept eating everything she put in front of me," Biden said, adding that Queen Elizabeth was always "decent, honorable and all about service."
Biden, known for the losses he’s experienced in his own life as well and his powerful eulogies he's delivered over the years, said the queen's death "leaves a giant hole" that seems impossible to overcome.
"But, as I’ve told the king, she’s gonna be with him every step of the way, every minute, every moment and a reassuring notion," Biden said.
Biden offered a special expression of condolences to the people of the United Kingdom, saying they were blessed to have the queen on the throne for more than 70 years.
"We all were," Biden said. "The world's better for her."
Biden said the way the queen leaned over and touched people during public appearances and offered reassuring looks, reminded him of his own mother.
"It's about treating people with dignity,” Biden said. “I talked about how my mother and father thought that everyone, no matter who they were, no matter what their station, no matter where they're from, deserve to be treated with dignity. And that's exactly what she communicated."
