The Gandhian era, which lasted from the early 1900s to Gandhi's death in 1948, saw the rise of nonviolent resistance and civil disobedience as powerful tools for social and political change.

His principles of truth, nonviolence, and self-reliance continue to have a profound impact on movements for justice and equality globally.
