Plenty of democratic countries have monarchs. Most of Europe still has monarchs, because they're constitutional monarchies -- which is a fairly common democratic form of government.

What matters is not whether there is a king, but the details of how the specific powers are allocated between the different parts of government. Sweden is also a constitutional monarchy, with a king.

Two of European monarchies are also peculiar in that they are elective: the Vatican and Andorra. (The Vatican is also technically a theocracy)
