The document summarizes various modern art movements that emerged between the 1860s and 1970s, including Imagism, Expressionism, Dadaism, Symbolism, Cubism, and Surrealism. Imagism focused on precise, clear images and rebelled against sentimentality. Expressionism used vivid imagery and emotion to portray a dark side of human nature. Dadaism was anti-art meant to oppose existing art forms. Symbolism presented invisible ideas through visible representations. Cubism broke objects into abstract, rearranged geometric shapes from multiple views. Surrealism drew from dreams and the subconscious to create bizarre, dreamlike art without logical meaning.
