Constructivism was an avant-garde art movement that originated in Russia in the 1910s-1920s. It sought to reject the past and create an art that promoted order, unity, and peace. Key artists included Wassily Kandinsky, Laszlo Moholy-Nagy, El Lissitzky, and Alexander Rodchenko, who created reductive works using basic geometric elements that explored the relationship between art and its social function.
