Which one? I sometimes wonder whether the British Empire had been much much worse, as it always had the pretense of a democracy, and being civilized, but it has to have been one of the most treacherous of empires ever. With an enormous ability to double talk. I am almost convinced that this is how the English language developed so many words that have double and triple meanings, depending how they are used. Compare this with German and Dutch words that exactly describe what they mean. I believe words in the Russian language also have a variety of meanings and can also be fickle.
The Russian Empire. Come on, they taxed people for having beards!
