Where I'm at, we hear a lot more about the British monarchs than any other monarchs.
For instance, I just found out that Norway, for instance, also has a monarch. So does Sweden (?), and several other countries. But they — the Nordic monarchs — are unheard of in my country, and don't seem to have the same level of influence internationally.
Is that your experience as well?
(FWIW, my country was a former British colony but the British royalty is NOT my country's head at all).
