The health of Queen Elizabeth declined rapidly earlier this month and by September 8, she died, with many of her family members around her. Many royal procedures followed, including a mourning period and the late monarch lying in state before she was buried beside her husband. In the midst of all this, Queen Elizabeth's death certificate has surfaced and provides more insight into the official cause of death, time, and circumstances. Outside of official documentation, Princess Anne, the queen's 72-year-old daughter, has been one of the most informative sources of details about the queen's last day, having been by her side for much of it. She is also the informant on the queen's death certificate, meaning she provided many of the details for the document's preparation. Here is what the certificate has revealed.
