My example was the implementation of the German orthography and language reforms between 1996 and 2006 (I went to elementary school in 2002, when implementing it was still in progress, and most stuff was still using the old spelling, I left high school in 2014).
But French has their Academy, which has even more power over language, and afaik, Spain supposedly has similar governing bodies.
Meh- the French Academy has power over prescriptive grammar sure, but it has almost no power over what descriptive linguistics finds. Lots of Arabic and Verlan has made its way into everyday parlance.
I'm not really sure that the French Academy is really that much more effective than Strunk & White is for English speakers. It primarily seems to be ceremonial / an expression of French pride.
