While soccer can be quite violent sometimes, we do not consider it an extreme sport. However, the original version, which dates back 600 years, could be one of the most violent sport events. This form of ancient extreme sport was practiced in ancient Florence, Italy and they called it Calcio Storico. Eventually, there are still people playing this tough game, there are even tournaments every year in Florence. It’s not for the faint hearted, the game can get really violent despite the strict rules.
