Edit: a modern example of it is the introduction of arabic language in Iranian schools after the revolution because arabic is the language of the Quran. A similar thing is done by China w.r.t. uighurs, which are not allowed to teach their language, and culture in schools, it has to be only Mandarin. Or, in Turkey, where by constitution it is prohibited to use any non-Turkish language as a language of instruction in schools.

So yeah.
