1.Dada was the first conceptual art movement where the focus of the artists was not on crafting aesthetically pleasing objects but on making works that often upended bourgeois sensibilities and that generated difficult questions about society, the role of the artist, and the purpose of art. Dada was also known as Anti-art, yet art. it was purposely the opposite of all typical artistic standards. Dada arose as a reaction to World War I, artist started protesting and criticizing society for them the world didn't make sense so art became nonsense and they used cheap and common objects so that viewers were forced to see object in a different way. The work "Napoleon's Nose, Transformed into a Pregnant Woman, Strolling His Shadow with Melancholia amongst Original Ruins" by Salvador Dalí, expresses his own metamorphosis, featuringthe most important symbols for dalí: the woman, the desert, the crutch and the crucifix, which are represented here in the shadows of the countryside, bathed in a critical paranoiac atmosphere. Irony lies in the fact that the title stresses the less apparent details of the work. In the deserted dream territory of Napoleon’s nose, its shadow and the pregnant woman are only small elements in a vast delirium.
2. Jacob Lawrence,was the first black artist to achieve prominence in what was still a largely segregated art world and society as a whole. According to WSWS, Diverse influences contributed to the unique style of this young artist. Lawrence was influenced by international artistic trends and social struggles. Among those he looked the great Mexican muralists, especially Jose Clemente Orozco.Moreover, his association with major figures of the Harlem Renaissance, Lawrence studied as a teenager in the Harlem Art Workshop, funded by the newly-established federal Works Progress Administration. In 1936 he enrolled at the American Artists School, where he met artists who were political activists involved in the Scottsboro case, the frame-up of nine black youth in Alabama on rape charges. During this period Lawrence also met the painter Gwendolyn Knight, who was to become his wife and who survives him, after 59 years of marriage. In the art work "The migrants arrived in great numbers"Lawrence took as his subject the exodus of African Americans from the rural South to Northern cities during and after World War I, when industry's demand for workers attracted them in vast numbers. As the son of migrants, Lawrence had a personal connection to the topic. He researched the subject extensively and wrote the narrative before making the paintings, taking seriously the dual roles of educator and artist.
