Prince William is largely known for his illustrious military career, his marriage to Catherine, the Duchess of Cambridge, and for being second-in-line to the throne of England.

However, before he became the charitable royal we all know and love, he was also a veritable heartthrob in the early 2000s.

Here are 15 photos of a young Prince William that will make you swoon.

Dubbed the “sport of kings,” polo is a family tradition for the Mountbatten-Windsors – both Prince William and Prince Harry have played it since they were very young.

While on a family ski trip in Switzerland circa 2005, Prince William posed alongside his father, Prince Charles.

Prince William also brought his then-girlfriend Kate Middleton on the family ski trip after rumours of their relationship first emerged two years earlier.

They were spotted by paparazzi cruising the slopes, although the royal family often organizes official photo-calls like this one to avoid getting snapped by other photographers on their vacations.

Prince William looked especially dashing at his father’s wedding ceremony to Camilla Parker Bowles on April 9, 2005.

Prince William is a surprisingly good polo player, especially given the fact that he’s left-handed and polo is required to be played using the right hand.

Prince William had just turned 24 a few days prior.

Before officially beginning his military career in January 2006, Prince William attended a Christmas Day service in a smart navy sport coat and a blue tie.

Prince William has had an illustrious military career.

In 2006, he was made Commodore-in-Chief of the Royal Navy Submarine Service.

Prior to this two-month-long attachment, Prince William completed a similar attachment training with the Royal Air Force.

Despite training with other sects of the British armed forces, Prince William spent the majority of his military career as a pilot with the Royal Air Force Search and Rescue Force.

Though the Prince of Wales began his training in 2008, he was officially stationed at a search-and-rescue base on the remote Welsh island of Anglesey in 2010.

According to CNN, he lived at the base along with Catherine, the Duchess of Cambridge.

Prince William still took time, however, to attend charity events and give back to his community.

While we usually see Prince William clean-shaven, he looked undeniably more grown-up with facial hair. It’s rumoured that the Prince of Wales grew the beard to disguise his identity during a Special Boat Service mission prior to beginning his RAF pilot training, according to The Telegraph.
