Postmodernity (post-modernity or the postmodern condition) is the economic or cultural state or condition of western society which is said to exist after modernity. Some schools of thought hold that modernity ended in the late 20th century—in the 1980s or early 1990s—and that it was replaced by postmodernity, while others would extend modernity to cover the developments denoted by postmodernity, while some believe that modernity ended after World War II. The idea of the post-modern condition is sometimes characterised as a culture stripped of its capacity to function in any linear or autonomous state as opposed to the progressive mindstate of Modernism.
