If you're following LeBron James on social media, then you could probably tell your friends that both his Instagram and Twitter handles are @KingJames. However, King James is more than just the name he uses online. That's also his most famous nickname.
Anyone who's familiar with history will know that King James was a ruler of both Scotland and England, who lived from 1566 to 1625, according to the BBC. As History.com notes, there's even a King James Version of the Bible. However, while the basketball player's nickname may be a play on the famous biblical figure, his nickname doesn't really have anything to do with the ancient royal.
Instead, Essentially Sports explains that although there are plenty of claims when it comes to how the athlete first earned his moniker, there's a general assumption that he gave it to himself. It was apparently his confidence in his playing ability that led him to deem himself as the king of the (basketball) court. Others think that it was members of the media who came up with the catchy name. Either way, it's stuck and has definitely become his most famous nickname, although it's certainly not the only one.
