A flag is a signal-giving piece of material. A loaded object and icon, which is often used as a symbol of politics, status, war, peace, territories, in connection with geopolitics and sports, but also the logo for various trademarks. All of the independent countries have flags, but there are also flags – such as the freestate Christiania's characteristic flag or (without comparison) the ISIS flag – which has iconic status, even though they do not represent nation states.
Flags produced by artists have a long and interesting history. There are many good reasons why flags are still relevant to the process and used within artistic and aesthetic practice. The symbol of the flag is used extensively in works during the last 100 years of art history. They are often covered with history and meaning, sometimes isolated like Jasper Johns flags (1954) or David Hammons African-American Flag (1990). Other times, the flag comments on a major political debate, for example, Eugène Delacroix, La Liberté guidant le peuple (1830), Poul Gernes proposal for an EC flag (1972), Daniel Buren's minimalistic Les Guirlandes (1982) on Documenta 7 in Kassel or Ai Weiwei's flag in connection with the 70th anniversary of the Universal Declaration of Human Rights (2018).
Since 2017, the park surrounding Kunsthal Aarhus has served as the venue for an annual outdoor exhibition featuring art flags: A Flag is a Piece of Fabric. The first flag was created for Kunsthal Aarhus 100 Anniversary by the artist Bodil Nielsen.
