What the Tupou Family Story Teaches Us

A father who reigned for forty-one years. An elder brother who reigned but had no heirs. A younger brother who served as Prime Minister before becoming King. A wife whose father was a national Baron. Three children carrying forward Pacific royal tradition.

For every family — large or small, famous or otherwise — the Tupou story carries the same lesson. Brothers sometimes succeed brothers. The Tupou royal succession passed from George V to Tupou VI because George V had no legitimate heir. Such horizontal successions are part of family history. Write them down.
