Peace symbols represent the idea of harmony and the absence of conflict. One of the most recognized symbols is the peace sign, which was created in the late 1950s for the British nuclear disarmament movement. It combines the semaphore signals for the letters "N" and "D," standing for "nuclear disarmament." Another important symbol is the dove, often depicted carrying an olive branch, which has roots in various cultures and religions. The dove represents hope and reconciliation, making it a universal emblem of peace. These symbols are widely used in protests, art, and literature to promote messages of non-violence and unity.
