Final answer:
Dadaism is an artistic movement that started in 1916 and largely concluded by 1930. It arose as a reaction to World War I and was considered anti-art, aiming to challenge and disrupt the traditional art world.
Step-by-step explanation:
Dadaism belongs to a period that began in the year 1916 and ended around 1930. This artistic and literary movement originated as a response to World War I and was characterized by its opposition to conventional standards and practices in art. Initially, it was an anti-art movement that protested against bourgeois nationalism and colonialism, which Dadaists viewed as root causes of the war. Dadaism's goal was to offend and subvert the art establishment, often utilizing found objects, collages, and photomontages. Although the movement lost momentum by the early 1920s, it had a lasting impact and paved the way for other modernist movements, like surrealism, and continues to influence contemporary art.
