Martial art had were used in the past ages but they continue their acme until today.
They were used in the past to help the weak and improve the powerful men. Men like Kings and Nobles learnt one martial art at least to defend themselves when they had to deal with a difficult situation.But knights and warriors were obliged to learnt a martial art too to defend themselves when they fought against their enemy and they learnt it to be more sure for their lives. Ofcourse all martial arts have their own equipment that you have to buy and take care.
Today police officers are obliged to know one martial art at least to do their duty to their country.The most usual martial art is Karate. But ordinary people learn a martial art too to protect themselves or just to improve their lifestyle, because martial arts are a way of life that you have to follow otherwise you break the rules of the speciffic martial art.
