Morihei Ueshiba (1883–1969) was the founder of Aikido. At age eighteen, Ueshiba joined the Japanese military, during which time he also developed his skills in the martial arts. He eventually left the military, deeply discouraged by the death and destruction that results from combat. Ueshiba continued to experiment with a variety of martial arts, finding particular joy in the spiritual aspects of martial arts. He came to believe that a real warrior was one who was rooted in love, and it was in this spirit that he began to develop Aikido, a martial art that emphasizes harmony and the peaceful resolution of conflict.
