title_body: Has any conlang ever replaced the use of a pidgin? I've read that being a simple, yet more expressive, substitute for a pidgin language is one of the possible applications of Toki Pona.
  
  In situations where people from multiple languages come together they need to be able to communicate with each other. Pidgins are introduced or developed in these situations, but there is a limited scope to what can be said in pidgins. Over time, pidgins creolise into full natural languages. I would like to know if a language like Toki Pona (or a similarly minimal conlang) has ever successfully replaced the use of a pidgin to allow more to be said, rather than letting the pidgin creolise naturally.
upvoted_answer: Basic English is minimal in that it limits the number of words in the language (though not as extremely as Toki Pona). It was intended to be an international auxiliary language (although it never really caught on).
  
  The language was used in 1945 in order to quickly teach Chinese sailors to understand naval orders. This was reported at the time in a Time magazine article (paywall beyond first two paragraphs; the reference to the article comes from Wikipedia).
