India's ancient martial art feared by the British Raj

Sanatan Shastar Vidya is an ancient martial art, which has existed in northern India for thousands of years.

It was adopted by the Sikh warriors in the 17th Century and is considered a spiritual as well as a physical exercise.

Today a more modernised version is practiced, known as 'Gatka' - which predominantly involves stick fighting and tactical positioning. It is now popular as a sport or sword dance performance art.
