The United Kingdom is one of the Commonwealth realms, which are sovereign states that share the same person as monarch and the same order of succession. In 2011, the prime ministers of the then-16 realms agreed unanimously to amend the rules of succession. Male-preference (cognatic) primogeniture was abandoned, meaning that males born after 28 October 2011 no longer precede females (elder sisters) in line, and the ban on marriages to Catholics was lifted. The monarch still needs to be in communion with the Church of England. After the necessary legislation had been enacted in accordance with each realm's constitution, the changes took effect on 26 March 2015.
