It is a martial art historically practiced by teenage Nguni herdboys in South Africa. Each combatant is armed with two long, hard sticks, one of which is used for defense and the other for offense with little or no armor used. Although Xhosa styles of fighting may use only two sticks, variations of Nguni stick-fighting throughout Southern Africa incorporate shields as part of the stick-fighting weaponry. Zulu stick-fighting uses an "isikhwili", an attacking stick, and "ubhoko", a defending stick or an "ihawu", a defending shield. The objective is for two opposing warriors to fight each other to establish which of them is the strongest or the "Bull" (Inkunzi). An "induna" or War Captain becomes a referee for each group of warriors, keeps his crew in check and keeps order between fighters. Warriors of similar affiliation did this when engaging in combat with one another. In modern times this usually occurs as a friendly symbolic practice part of the wedding ceremony, where warriors (participants) from the bridegroom's household welcome warriors from the bride's household. Other groups of participants may also be welcomed to join in.
