Nonviolence

Explanation:

Nonviolent resistance is a way of protest and social action that relies on the acts of civil disobedience and political noncooperation that do not include any violent act.

Gandhi's salt march is one of the more famous examples. It was the nonviolent resistance that urged for India’s independence and against the colonial rule of the British monarchy. In 1930 the British government introduced taxes on Indian salt and strengthen their monopoly by prohibiting Indians to collect and sell salt. Gandhi and his followers started daily marches during which they symbolically carried salt that has symbolically been picked up from the beach, thus breaking the rule.

Similarly, the Civil rights movement has been fighting racist laws and ideas against African Americans during the 60s in the US. The African-American community showed their resistance by breaking segregation laws with bus boycotts and freedom rides, as well as participating in non-violent sit-ins, marches, and demonstrations.
