Modernism began around 1900. It was a rejection of tradition and an attempt to see the world differently. Events such as World War 2 and the Great Depression made many feel modernism had failed. This led to postmodernism, which is cold and skeptical of the grand narrative of Western Society. This grand narrative is explained by Jean-François Lyotard as something. Postmodernism is a very broad term that cannot be defined by specific themes. It is an all-encompassing way of thinking.
