Who first developed the strategy of nonviolent protest

Non-violent resistance or non-violent protests are practices where goals were to be achieved without any violence through symbolic protests, satyagraha etc.

The concept was first introduced my Mohandas Karamchand Gandhi in India, who followed Satyagraha.

These teachings and prophecies became widespread globally and were followed by Civil rights leader Rev. Martin Luther King during the American Civil Rights Movement during the fight for racial equality.
