The young royal is second-in-line to the throne after his father, Prince William and we've seen him pass many milestones over the years.
From George's public debut to the world on the steps of the Lindo Wing where he was born in 2013, to his first royal tour and first day at school.
To prepare him for his future role, the young Prince has made more public appearances in recent years.
George played a major part at King Charles's coronation in May 2023 as one of his grandfather's Pages of Honour.
And he shares a love of sport with his parents, particularly football, recently travelling to Germany for his first match abroad at the Euro 2024 final.

Prince George's public debut
The lead-up to Prince George's birth on a hot summer's day sparked the #GreatKateWait as it was dubbed in the new social media age, with the media and fans eagerly waiting for news outside the Lindo Wing at St Mary's Hospital in Paddington for over three weeks.

First royal tour
Prince George attended his very first public engagement at Government House in Wellington, New Zealand where he enjoyed a special playdate with a group of children all born around the same time as him. The eight-month-old looked cute as ever as he played with toys while wearing a pair of navy Rachel Riley dungarees.

First day at school
A nervous-looking George arrived in his new uniform for his first day of school at Thomas's Battersea in September 2017.

First overseas football match
