Postmodernism is a complex philosophical and cultural movement that emerged in the mid-20th century, characterized by a skeptical, critical approach to concepts of truth, authority, and narrative. It challenges the grand narratives and ideologies of modernism, embracing a fragmented perspective that values diversity, pluralism, and subjectivity. This movement has significant connections to art, literature, architecture, and critical theory, reshaping how societies interpret their histories and cultural legacies.
