Who is the eldest son of the Queen?

Okay, let's talk about the line of succession to the British throne. It's a system that's been evolving for centuries, and it basically determines who becomes the next monarch. The key principle is primogeniture, meaning the eldest child inherits the throne, regardless of gender since 2013. Queen Elizabeth II had four children: Charles, Anne, Andrew, and Edward. Because Charles is the eldest, he is first in line to the throne. So, Prince Charles is the eldest son of the Queen, making him the heir apparent. While Prince William is also very prominent and popular, he's actually Charles's eldest son and therefore second in line. Prince Andrew and Prince Edward are further down the line of succession because they are younger than Charles. It's all about birth order!
