Persona Grata facts
While investigating facts about Persona Grata, I found out little known, but curios details like:
Spanish footballer Diego Costa was actually born and raised in Brazil, even earning 2 caps for Brazil, until he switched allegiance to Spain after being granted citizenship in 2013. This led him to be branded a traitor and declared "persona non grata" at the Brazil national team.
Former Austrian President and United Nations Secretary-General Kurt Waldheim was declared Persona Non Grata in several countries due to his work as a Nazi Intelligence Officer
In my opinion, it is useful to put together a list of the most interesting details from trusted sources that I've come across. Here are 2 of the best facts about Persona Grata I managed to collect.
