The royal line of succession is the order in which members of the Royal Family would come to the throne — if the reigning king or queen died or abdicated. Williams, Prince of Wales, is first in line, followed by his son, George, and then his daughter, Charlotte. Traditionally, males came before females in the line of succession. But in 2015, the law changed so that for children born after October 28, 2011, the succession is decided by age versus gender.
