Succession to the British Throne is determined by a set of rules that dictate who can inherit the crown. The current line of succession is based on descent, legitimacy, and religion, with the first in line being the eldest child of the reigning monarch, currently King Charles III. Changes to the rules were made in 2013, allowing for absolute primogeniture, meaning the eldest child, regardless of gender, inherits the throne. This means that Prince William is next in line, followed by his children, Prince George, Princess Charlotte, and Prince Louis.
