King Charles' family remembers his father Prince Philip on birthday

The British royal family on Tuesday celebrated the birthday of the late Prince Philip, the father of King Charles III, who died in 1921 at the age of 99.

While the official social media accounts of the royal family didn't share any post to mark the birthday, the Royal Collection Trust paid a tribute to the husband of the late Queen Elizabeth II.

However, a like from Royal Family's Instagram account was visible on the Royal Collection Trust.

The trust shared a photo of the late royal's paining with a brief statement on his family and his roots.

According to the caption that accompanied the Instagram post, "Prince Philip, Duke of Edinburgh was born on this day in 1921. This portrait was painted by Ralph Heimans, to mark the Prince’s retirement from public duties in 2017 at the age of 96. Prince Philip was married to Queen Elizabeth II for 73 years."

In the painting he can be seen wearing Windsor Uniform, with the pale blue sash and badge of the Danish Order of the Elephant.

The caption read, "The impressive background setting of the Grand Corridor at Windsor Castle and the order make close reference to the sitter’s ancestry. Prince Philip was born a prince of Greece and Denmark; his grandfather, George I of Greece, was brother to Queen Alexandra."

"His maternal grandmother, Princess Victoria of Hesse, and his mother, Princess Alice of Battenberg, were both born in the Tapestry Room situated at the end of the Corridor. Princess Victoria was a granddaughter of Queen Victoria."
