More Than 45 Years of ISDS
Founded in Belgium in 1980, the International Self Defence School has more than four decades of history in practical self-defence and martial arts training.
Throughout the years, the school has continued to develop by bringing together knowledge from different martial arts traditions while remaining focused on realistic and effective self-defence.
This rich history is reflected in the ISDS logo, which brings its core martial arts systems together within golden circles symbolising personal growth, continued learning and the wider world of martial arts.
