IN CONTEXT: Art Changes History

Art forms and methods are as varied as the times in which they are created, yet not all art has equal impact. While some art is solely decorative, some becomes active, exerting effects across the world. Art can change history, and it does so through mechanisms that are not accidental. They are purposeful and can be observed across time and across creative disciplines, from painting to photography to film.

Art as Witness

Art can expose truth and make it unavoidable, revealing realities people cannot ignore. In The Third of May 1808, Francisco Goya breaks with conventional practice by not depicting heroic war imagery centered on victors. Instead, he turns our gaze to the victims, generating emotional immediacy through his use of light, gesture, and the portrayal of fear. In doing so, he forces the viewer into a moral position of sympathy.

As art travels, its impact multiplies. The documentary realism of Migrant Mother by Dorothea Lange put a human face on an economic crisis, and as it circulated widely, it had a direct influence on public awareness and policy.

These are examples of art as witness. Witnessing leads to empathy, and empathy can lead to action.

Art as Propaganda

Art shapes belief, not just perception, and in doing so it can override critical thinking. In Triumph of the Will, Leni Riefenstahl uses mastery of visual language—scale, repetition, and movement—to manipulate the viewer emotionally through spectacle, legitimizing power through aesthetic beauty.

Similarly, American Progress by John Gast utilizes the powerful technique of normalizing harmful ideas by making them appear natural. In his visual narrative of westward expansion, he presents an idealized vision of inevitable “progress,” reinforced with symbols of advancement—telegraph wires, books of learning, and railroads—while subtly promoting the erasure of Indigenous presence.

These are examples of art as propaganda, and propaganda can be beautiful and inspiring, not always aggressive or overt.

Art as Protest

Art challenges power and reshapes consciousness. In Guernica, Pablo Picasso uses a limited palette, scale, and fragmentation to mirror and expose chaos and violence. The global circulation of the image brought international awareness, and it became a symbol of the horrors of war, the suffering of innocents, the failure of authority, and collective trauma—extending far beyond the bombing of the town of Guernica itself.

Art turns a moment into a universal symbol.

Art is most powerful when it reaches beyond elite audiences and enters the public consciousness. In The Problem We All Live With, Norman Rockwell presents a young Black girl walking to school, surrounded by U.S. Marshals. On the wall behind her are a smashed tomato and a partially visible racial slur. The mob is not shown, but its presence is clearly implied.

Rockwell’s protest is powerful precisely because it does not look like protest at first glance. Known for images of comfort, familiarity, and idealized American life, he uses that same visual language here to address violence and systemic injustice. Expecting comfort, the viewer is instead confronted.

This is America too.

The painting exposes the gap between what America claims to be and what it is. It presents dignity and composure against a violence that remains off-screen but unmistakably real. Published in Look Magazine, it entered everyday homes and reached a mass audience. It forced viewers—especially white viewers—to see civil rights not as an abstract issue, but through the experience of a child.

Rockwell protests by revealing, not exaggerating. Nothing is heightened, yet everything is exposed.

These are examples of art as protest—strength without violence, quiet yet powerful.

Art as Disruption

Art changes how we think—not just what we think about. In Fountain, Marcel Duchamp used an existing object—a urinal—and declared it to be art. In doing so, he removed skill as a requirement, introduced the idea as central, and redefined authorship. He changed the rules of art itself.

In a similar way, Campbell’s Soup Cans by Andy Warhol blurred the boundaries between high art and low art, between art and commerce, and between the singular object and mass production. Warhol elevated everyday objects to artistic status, collapsing distinctions and reshaping cultural perception.

Conclusion

The mechanisms of art are powerful. They operate across different intentions, times, and styles, yet their effects are profound. As witness, art reveals and exposes. As propaganda, it persuades. As protest, it challenges and confronts. As disruption, it redefines.

Art needs only to be created—and once it enters the world, it begins to act. History is changed from that moment forward.
