Thursday was a big day for Prince William, who was installed as a Knight of the Order of the Thistle by his grandmother, Queen Elizabeth II during a ceremony in Scotland. The honor is considered the highest available in the country.
"It is our pleasure that His Royal Highness the Prince William, Earl of Strathearn, be installed a Knight of the most ancient and most noble Order of the Thistle," the Queen, 86, announced during the ceremony, which is part of her Diamond Jubilee celebrations in Scotland. (Her engagements in England wrapped in early June.)
The 30-year-old prince joins his father, Prince Charles, his grandfather, Prince Philip and his aunt, Princess Anne as part of the Order's Extra Knights and Ladies. As an "Extra Knight," he will not count toward the Order's 16-member limit (consisting of several politicians, doctors and scholars) but will be recognized as The Earl of Strathearn.
This isn't William's first appointment as Knight. In 2008, he was invested as Royal Knight Companion of the Most Noble Order of the Garter, making him the thousandth to receive the highest British honor of chivalry, which recognizes his seniority within the royal family, since the Order was formed in 1348.
