The art of Aikido was founded by Morihei Ueshiba. Morihei devoted himself to hard physical conditioning. He practiced martial arts; earning certificates of mastery in several styles of Jiu-Jitsu, fencing, and spear fighting. By combining his martial arts training with his religious and political ideologies, he founded modern Aikido. He decided on the name “Aikido” in 1942. Before that this style was known as “Aikibudo” and “Aikinomichi”.
Aikido is rooted in several styles of Jiu-Jitsu. It is also from the arts of sword and spear fighting. Many of the Aikido techniques are the result of master Ueshiba’s own innovation.
There is no unified philosophy of Aikido. The techniques of Aikido are either shared by word of mouth or found in scattered publications of Aikido.
