Throughout history, artists have joined forces with political movements to battle injustice and demand a better and more beautiful world. Picasso's "Guernica" captured the horrors of the German bombing of civilians in 1937. "Solidarity Forever," "We Shall Overcome," and "Give Peace a Chance" expressed the optimism and power of the labor, civil rights, and peace movements. Delacroix's "Liberty Leading the People" embodied the utopian fervor of the French Revolution. Shepard Fairey's Obama "Hope" silkscreen during the 2008 election captured America's yearning for a more visionary politics.
