English is a business language because one European power took over after another.
The global domination of European civilization was already a fact at the time.
And by the way Romans and Slavs are European too.
The irony is that because of all the refugees who are coming to Europe, most of whom speak English, the host countries may be forced to adopt English as an official language, because let’s face it, somebody from Africa, isn’t going to be highly motivated to learn Swedish if they already speak English.
I know Romans and Slavs are Europeans - and their air traffic controllers speak English, not Latin or Russian. I said “the course of European history” was determined by northern Europe and the British Isles.
