I understand that the official court language of Imperial Russia was
French.

Were there other countries that had an official court language that was
not the common tongue of the people?

England was the same in earlier times.

How Prussia under Frederick the Great?

Instead of Bohemia and Hungary one would rather say the court of Vienna
(much depending of Bohemians of German tongue) and of Hungary (strong
influence of Latin). There is hardly a common tongue. Every soical,
professional, etc group has its own language, that can be used such,
that the other does not understand.

Turenne...

I believe that the language spoken in the Japanese court was completely
different to that spoken by the hoi polloi.
