Monarchy is built on tradition, and naming is no exception. In Britain’s royal family, clear patterns and customs have guided the names of those crowned king.
Despite the fact that when they're born future monarchs have no power over the names they are given, they do have some say over their regal name – the name they use as king or queen.
A monarch can choose any of their given names. For example, Queen Victoria was christened Alexandrina Victoria but chose her second name, Victoria.
Some names carry historical weight or signal continuity with past rulers. Edward VII chose Edward, a name with a long history in England. George VI chose George to maintain continuity with his father, George V.
Today, monarchs often pick a name by which they are already widely known to avoid confusion. King Charles III kept his first name as his regnal name, despite Charles being historically an unlucky name for a king.
Charles I is best remembered for being overthrown by Oliver Cromwell and executed. Charles II was considered unlucky as he had no legitimate heir, and his reign saw both the Great Plague of 1665 and the Great Fire of London in 1666.
