Succession to the British throne is determined by descent, gender (for people born before October 2011), legitimacy, and religion. The line of succession was changed in 2013.
Under the Succession to the Crown Act, princes no longer take precedence over their sisters, bringing an end to the system of male preference primogeniture which had been in place since the Act of Settlement of 1701.
