Every village and tribe around the world had a few experienced fighters who passed on their knowledge; however, it is difficult to pass on a fighting system, so almost all of these have been lost as their practical relevance has declined. A few have nonetheless survived for one reason or another, examples of this are Capoeira and some related arts in Cuba, Haiti and Trinidad and Tobago, which were preserved partly through their relationship with Candomblé, Santería, Vodun, and other syncretic religions.[citation needed] Of these, only Capoeira has risen to worldwide prominence. Archery, Boxing, Fencing, Javelin, Judo, Wrestling and Tae Kwon Do are the martial arts that are featured as events in the modern Summer Olympic Games.
