Boychukism is a cultural and artistic phenomenon in the history of Ukrainian art between the 1910s and 1930s, distinguished by its artistic monumental-synthetic style. It was an original school of Ukrainian art, formed by a synthesis of Ukrainian folk art and the church art of Byzantium, Proto-Renaissance and Ukraine. The name comes from the name of the founder of the movement: Mykhailo Boychuk, monumentalist and graphic artist.
