Esperanto was first developed in Europe in 1897 to be the world language it's a mix of romance and slavic languages. It's easy to learn and very fun to speak and it has many solutions to travel problems today. Say your going to France and don't know how to speak French, well if everybody know how to speak Esperanto it would be easier for tourists officials away on business meetings and would all in all bring countries closer together. Maybe one day we can use it during divine liturgy (though it's unfortunate it's associated with communism).
