Spain effectively lost its monarchy status by popular will, and it took a violent and very bloody coup to reinstate it - but even then, as a ceremonial puppet. Similarly the UK. I am not familiar with Sweden but from what I occasionally read, the Swedish crown lost pretty much all its power too. Monarchy as an institution is fundamentally bad in the long run, because belonging to a certain family is no guarantee of competence in government - something that the Romans had already discovered.
