Graffiti are scratched, or painted writing or drawings that have been scribbled, illicitly on a wall or other surface, often within public view.

Graffiti range from simple written words to elaborate wall paintings, and they have existed since ancient times, with examples dating back to Ancient Egypt, Ancient Greece, and the Roman Empire.

In modern times, paint (particularly spray paint) and marker pens have become the most commonly used graffiti materials. In most countries, marking or painting property without the property owner's permission is considered defacement and vandalism, which is a punishable crime.

Graffiti may also express underlying social and political messages and a whole genre of artistic expression is based upon spray paint graffiti styles. Within hip hop culture, graffiti have evolved alongside hip hop music, b-boying, and other elements. Unrelated to hip-hop graffiti, gangs use their own form of graffiti to mark territory or to serve as an indicator of gang-related activities.

Controversies that surround graffiti continue to create disagreement amongst city officials, law enforcement, and writers who wish to display and appreciate work in public locations. There are many different types and styles of graffiti; it is a rapidly developing art form whose value is highly contested and reviled by many authorities while also subject to protection, sometimes within the same jurisdiction. Modern-style graffiti The first known example of "modern style" graffiti survives in the ancient Greek city of Ephesus (in modern-day Turkey).

Local guides say it is an advertisement forprostitution. Located near a mosaic and stone walkway, the graffiti shows a handprint that vaguely resembles a heart, along with a footprint and a number. This is believed to indicate that a brothel was nearby, with the handprint symbolizing payment. The ancient Romans carved graffiti on walls and monuments, examples of which also survive in Egypt.

Graffiti in the classical world had different connotations than they carry in today's society concerning content. Ancient graffiti displayed phrases of love declarations, political rhetoric, and simple words of thought, compared to today's popular messages of social and political ideals The eruption of Vesuvius preserved graffiti in Pompeii, which includes Latin curses, magic spells, declarations of love, alphabets, political slogans, and famous literary quotes, providing insight into ancient Roman street life.

One inscription gives the address of a woman named Novellia Primigenia of Nuceria, a prostitute, apparently of great beauty, whose services were much in demand. Graffiti writing is often seen as having become intertwined with hip hop culture and the myriad international styles derived from New York City Subway graffiti.

However, there are many other instances of notable graffiti in the twentieth century. Graffiti have long appeared on building walls, in latrines, railroad boxcars, subways, and bridges. The example with the longest known history, dating back to the 1920s and continuing into the present day, is Texino. Some graffiti have their own poignancy. In World War II, an inscription on a wall at the fortress of Verdun was seen as an illustration of the US response twice in a generation to the wrongs of the Old World.
