Almost single-handedly, the future king of England, eldest son of Prince Charles and the late Princess Diana, has transformed the stale, stuffy image of the Royal Family and brought it into the 21st century. Bearing the burden of his beloved mother’s legacy, William, along with his brother, Prince Harry, have ruled through their lack of pretense and an authentic eagerness to mix with the commoners.

But it’s his marriage to Kate Middleton and the couple’s two adorable children that have revived the story-book charm that people expect from the Royals. While honoring his duties, William has dedicated himself to working for environmental causes. Protect the realm, indeed.
