Step-by-step explanation:
Violence has been a controversial method used throughout history to bring about change. The effectiveness and necessity of violence in achieving change depend on the specific historical context and the goals of the change sought. For example, in some political revolutions, violence was seen as necessary to overthrow oppressive regimes and establish new governments. However, it can also be argued that violence is not always necessary, and other peaceful methods like nonviolent civil disobedience, voting, or challenges in the courts can also bring about change. In the 1960s, for instance, the civil rights movement in the United States achieved significant progress through nonviolent protests, grassroots campaigns, and legal challenges.
