Aikido, extraordinary martial art;

Aikido (Japanese: 合気道 Hepburn: Aikidō^?) [a.i.ki.doː] is a modern Japanese martial art developed by Morihei Ueshiba as a synthesis of his martial studies, philosophy, and religious beliefs. Aikido is often translated as "the way of unifying (with) life energy"^[1] or as "the way of harmonious spirit."^[2] Ueshiba's goal was to create an art that practitioners could use to defend themselves while also protecting their attacker from injury.^[3][4]

Aikido techniques consist of entering and turning movements that redirect the momentum of an opponent's attack, and a throw or joint lock that terminates the technique.^[5]

Aikido derives mainly from the martial art of Daitō-ryū Aiki-jūjutsu, but began to diverge from it in the late 1920s, partly due to Ueshiba's involvement with the Ōmoto-kyō religion. Ueshiba's early students' documents bear the term aiki-jūjutsu.^[6]

Ueshiba's senior students have different approaches to aikido, depending partly on when they studied with him. Today aikido is found all over the world in a number of styles, with broad ranges of interpretation and emphasis. However, they all share techniques formulated by Ueshiba and most have concern for the well-being of the attacker
