Graffiti's history spans from ancient civilizations to modern urban landscapes, evolving into a complex art form that challenges traditional notions of public space. It reflects societal changes, cultural movements, and serves as a voice for marginalized communities, often sparking debates about vandalism versus legitimate street art.

Modern graffiti emerged in the late 20th century, closely tied to youth culture and urban identity. It transformed from simple tags to complex murals, influencing graphic design, fashion, and contemporary art. Graffiti's evolution reflects changing city dynamics and often serves as a form of resistance against gentrification.
