According to one legend, the cocktail was invented at the end of the 19th century in The American Bar in Havana, where the American military loved to relax. US Army Captain Russell often ordered his favorite drink: a mixture of Cuban rum, cola and lime juice. In response to a question from his colleagues about the name of the cocktail, Russell made a toast - “Por Cuba libre!” (“For a free Cuba!”), and since then the drink has been called that.
