Protest symbols are visual representations used to convey messages during social movements or demonstrations. These symbols can include signs, logos, or specific colors that represent a cause, such as the rainbow flag for LGBTQ+ rights or the fist symbol for solidarity and resistance. They help unify participants and communicate their demands to a broader audience. These symbols often carry historical significance and can evolve over time. For example, the peace sign originated in the 1950s as a symbol for nuclear disarmament but has since been adopted by various movements advocating for non-violence and social justice.
