After the death of Morihei Ueshiba, aikido gradually stopped developing as a single technical environment.
Different lines, organizations and interpretations began to appear inside the art itself.
Some attempted to preserve the hardness of the early period.
Others focused on Ki, weapons practice, flowing movement, or the connection between aikido and classical budo.
As aikido spread beyond Japan, the art also began to change through different cultures, national federations and teaching systems.
This book explores the postwar evolution of aikido through:
historical lines,
organizations,
regional schools,
technical disagreements,
and the people who attempted to preserve Morihei Ueshiba's legacy in different ways.
Without trying to define a "correct" version of aikido.
Only history,
facts,
and the evolution of a system that became far more complex after leaving Japan.
