Postmodernism emerged as a reaction against modernism's limitations, rejecting universal truths and embracing pluralism. It questions artistic authority, blurs high and low culture, and draws from post-structuralism and deconstruction. This movement gained prominence in the 1960s-70s, influenced by social movements and globalization. Institutional Critique, a key aspect of postmodernism, examines how art institutions shape art production and reception. Artists like Hans Haacke and Andrea Fraser exposed hidden biases and power structures in the art world. This practice has had lasting impacts, influencing contemporary artists to challenge traditional boundaries and hierarchies.
