Ultimogeniture, also known as postremogeniture or junior right, is the tradition of
inheritance by the last-born of the entirety of, or a privileged position in, a
parent's
wealth,
estate or office. The tradition has been far rarer historically than
primogeniture, inheritance by the first-born.Ultimogeniture serves the circumstances where the youngest is "keeping the hearth", taking care of the parents and continuing at home, whereas elder children have had time to succeed "out in the world" and provide for themselves - or having received some of their share earlier, for example when marrying and founding an own family. Remembering the then usual low age at death, the system has been relatively impractical for impartible inheritance during past centuries. Ultimogeniture has been more suitable to officeholders and owners who have themselves been adults already for several decades (such as monarchs who happen to be elderly) and are leaving children who are more or less all mature adults.
