Martial arts are systems of coified practices and traditions of training for combat. While they maybe studied for various reasons, martial arts share a single objective: to defeat a person physically or to defend oneself from physical threat. In addition, some martial arts are linked to spiritual or religious beliefs/philosophies such as Hinduism, Buddhism, Daoism or Shinto, Confucianism, and even Islam (by Chinese Muslims) while others have their own spiritual or non-spiritual code of honour. Many arts are also practised competitively most commonly as combat sports, but may also be in the form of dance.
