Frequently Asked Questions

What is the difference between primogeniture and ultimogeniture?

Primogeniture gives the inheritance to the eldest child; ultimogeniture, sometimes called borough English, gives it to the youngest. Ultimogeniture was rarer but suited households where older children had already been set up elsewhere and the youngest stayed to work the land.

What is absolute primogeniture?

Absolute primogeniture means the eldest child inherits whatever their sex, so an elder daughter is not displaced by a younger son. Several European monarchies adopted it in the late twentieth century, and the United Kingdom applied it to those born after October 2011.

Why did primogeniture exist?

It kept estates intact. Splitting land equally between all children divided a holding into unviable fragments within a couple of generations, so societies that depended on large landed estates for military service and revenue concentrated the inheritance in one heir.
