Modern art began in the late 19th century after Impressionism and includes styles like Cubism, Minimalism, and Abstract Expressionism. It broke from traditional realistic depictions and allowed more freedom of expression. World Wars I and II exposed American artists to European styles and helped modern art gain popularity in the US. Artists like Jackson Pollock and Robert Rauschenberg used new techniques like dripping paint and incorporating found objects. Modern art continues to evolve as artists find new ways to comment on and interpret the modern world.
