Prince Charles is the eldest son of Queen Elizabeth II and is therefore at the front of the line of succession. Many people believe that he might, in case of the Queen’s eventual death, not take the throne after all and step aside for his firstborn son, Prince William.
Prince William is on second place in line for the throne, right behind his father, Prince Charles. He might even take the throne instead of Prince Charles, who is already almost 70 years old.
Prince George is third in line to the throne, although he might not yet be able to really grasp what his responsibilities are going to be in the future.
Prince George's little sister, Princess Charlotte, is fourth in line of the British throne.
The little Louis might be the youngest member of the royal family, but he also took on the fifth place in the line of succession for the British throne when he was born on April 23rd of 2018.
Prince William's younger brother, Prince Harry, used to be ranked third in the line of succession. After the birth of his two nephews and niece, however, he has been "demoted" to the sixth place by now.
Although Prince Andrew is the second son of Queen Elizabeth II, he is only seventh in the line of succession.
The eldest daughter of Prince Andrew, Princess Beatrice of York, is eighth in line to the throne - right after her father.
As the youngest son of the British Queen, Prince Edward ends up on the tenth place of succession.
