Prince William was very impressed with his dad, Prince Charles, when he was a kid.

The Duke of Cambridge was very proud that his father would be king one day that he often asserted his dad’s status up to a point where he got into fights.

In Katie Nicholl’s 2010 book “William and Harry,” she delved into the early lives of the Prince and late Princess of Wales’ sons. According to the royal expert, when Prince William started nursery school in 1985 he instantly became popular with his new friends because he would always take charge.

“When it came to playtime, William was already aware of his princely status," Nicholl wrote.

“When he got into a scrap, a common event for the boisterous youngster, he would draw his play sword and challenge his opponent: ‘My daddy’s a real prince, and my daddy can beat up your daddy,’ he would shout,” the Vanity Fair royal correspondent added.

Prince William was also considered a terror in class. He would reportedly push his way to the front of refreshment queues. Due to Prince William’s attitude, he gained the nickname “the Basher.”

Nicholl added that it was Princess Diana’s idea to send Prince William to a west London nursery. The People’s Princess wanted both of her children to mix with other kids their own age. However, Queen Elizabeth II was hoping to educate the Duke of Cambridge at home to keep the royal tradition.

Queen Elizabeth II wanted Prince William to be ready by the time he takes over the throne after his father, Prince Charles. In fact, Her Majesty has been preparing Prince William for the monarchy since he was a teenager.

Royal historian Robert Lacey revealed that when Prince William was a teen, the monarch would have him at Windsor Castle and they would open the state boxes. Queen Elizabeth II would guide her grandson through the papers.

Prince William and Prince Harry are both aware of what the former’s future role in the monarchy entails. When they were kids, the Duke of Sussex already acknowledged his older brother’s kingship and even boasted that he could do anything because he won’t be king.
