Prince Philip died on Friday at the age of 99.
Buckingham Palace did not give a cause when announced his death, but it followed a long history of health issues.
Philip, also known as the Duke of Edinburgh, had been released from the hospital on March 16 after a month-long stay.
He had been admitted after feeling poorly, and later had what was described as a successful procedure for a pre-existing heart condition.
This was his longest ever stay in hospital. But the duke had had a series of hospital stays over the past decade, during some of which he missed important public engagements.
In 2011, at age of 90, Prince Philip spent four nights in hospital after experiencing chest pains. He underwent an operation to place a stent to treat a blocked coronary artery at Papworth Hospital in Cambridgeshire on Christmas Eve 2011.
The Duke also suffered from bladder infections, which made him miss the some of the queen's Diamond Jubilee celebrations in 2012 and the opening ceremonies of the 2012 Paralympic Games.
In 2013, he spent 11 days in hospital for planned exploratory surgery on his abdomen.
He was also admitted to hospital in 2017 "as a precautionary measure" for treatment of an "infection arising from a pre-existing condition."
In a statement, the Palace said Prince Philip was "disappointed" to be missing the Queen's speech which marked the opening of parliament that year.
In 2019, he was admitted to hospital for 5 days for a "pre-existing condition," although it wasn't clear if this was related to his heart condition.
Prince Philip would have turned 100 in June. He once said he couldn't imagine anything worse than reaching that age, Insider's Mikhaila Friel reported.
He passed away "peacefully this morning at Windsor Castle", Buckingham Palace said in its statement on Friday.
