Philip, Duke of Mecklenburg Philip, Duke of Mecklenburg Philip, Duke of Mecklenburg, sometimes called "Philip I" (12 September 1514 - 4 January 1557) was a Duke of Mecklenburg-Schwerin. He was the youngest son of Henry V, Duke of Mecklenburg, and Helen of the Palatinate, a daughter of Philip, Elector Palatine. As a result of an injury at a tournament he was mentally ill for many years. After Henry V's death in 1552, he lived at the court of Duke Ulrich of Mecklenburg in Güstrow, where he died. Whether he ruled actively is questionable in the light of his disability. He was buried in the
Prince Philip, Duke of Edinburgh to celebrate a platinum wedding anniversary. On 3 April 2018, Philip was admitted to the King Edward VII Hospital for a planned hip replacement, which took place the next day. This came after the Duke missed the annual Maundy and Easter Sunday services. On 12 April his daughter, Princess Anne, spent about 50 minutes in the hospital and afterwards said her father was "on good form". He was discharged the following day. On 19 May, six weeks later, he attended the wedding of his grandson Prince Harry to actress Meghan Markle and was able to walk with the Queen unaided.
