A democratic system in which the named “ruler” is a symbolic head of state, and power rests in the hands of elected officials is the constitutional monarchy.

Explanation:

Constitutional monarchy is a form of state in which there is separation of powers, where the monarch holds the Executive Power appointing the government, while the Legislative Power, is exercised by an assembly or parliament, usually elected by citizens.

In opposition to absolute monarchy, political science distinguishes between constitutional monarchy and parliamentary monarchy. In the constitutional monarchies, the king retains the Executive Power. On the other hand, in the parliamentary monarchies, the Executive Power comes from the Legislative, which is elected by the citizens, the monarch being an essentially symbolic figure.

Current monarchies are mostly Parliamentarians.
