Morihei Ueshiba established Aikido as a contemporary Japanese martial art in the early 20th century. The phrase "way of harmony with the spirit" or "way of unifying life energy" is frequent translations.

Aikido emphasizes countering the energy and movements of the opponent as opposed to relying exclusively on one's own strength. The strategy places significant emphasis on integrating with the attacker's movements, deflecting their force, and countering assaults via throws, joint locks, and pins.

Circular motions and fluid motions are characteristic of Aikido techniques, which are intended to subdue and control an opponent without inflicting excessive damage. Achieving a condition of mental and physical harmony is the objective of practitioners; these states are frequently denoted as "ai," "ki," and "way," respectively.

Aikido instruction prioritizes mental discipline, self-improvement, and a philosophy of peaceful resolution in addition to physical techniques. As a result of its emphasis on self-defense, nonviolent conflict resolution, and personal development, Aikido is regarded as a path to spiritual and physical development in addition to a martial art.
