form of government.
There are contemporary [federal] constitutional monarchies in
some countries (Malaysia, Bhutan, United Arab Emirates, United
Kingdom), and unitary constitutional monarchies in others
(Australia, Belize, Belgium, Solomon Islands).
It is more of a technicality whether or not you can classify

SHORT ANSWER-a descendent/birth Many different systems for succession are in use. In hereditary monarchies (most common), the successor is a descendent or other relative of the sitting monarch. In elective monarchies (Malaysia, United Arab Emirates, Vatican City State), the successor is elected or appointed (such as by an electoral college) for life. Some monarchs are appointed by their predecessors.
In constitutional monarchies, the rules for succession may be under the control of a legislative assembly such as a Parliament (eg Commonwealth Realms).
