Graffiti in Iran consists of different styles. Some are slogans painted by governmental organizations, and some are works of art by regular citizens. During the last few years, Tehran Municipality has been drawing graffiti (more properly named "murals") in order to beautify the city. Much governmental graffiti regards the Iranian Revolution, Islamic Republic of Iran policies and The Politics of Resistance. Pro-democracy activists are also continuing a political graffiti campaign in Tehran. Islamic graffiti can also be seen around the city. Graffiti has long served as a medium of expression through Iran's complicated political history.
