One demarcation point of this era is the collapse of the Soviet Union and the liberalization of China in 1991. Francis Fukuyama wrote "The End of History" in 1989 in anticipation of the fall of the Berlin wall. He predicted that the question of political philosophy had been answered, that large scale wars over fundamental values would no longer arise since "all prior contradictions are resolved and all human needs satisfied." This is a kind of 'endism' also taken up by Arthur Danto who in 1984 acclaimed that Andy Warhol's Brillo boxes asked the right question of art and hence art had ended.
