The Hurufiyya movement (Arabic: حروفية ḥurūfiyyah adjectival form ḥurūfī, 'of letters' (of the alphabet) is an aesthetic movement that emerged in the second half of the twentieth century amongst artists from Muslim countries, who used their understanding of traditional Islamic calligraphy within the precepts of modern art. By combining tradition and modernity, these artists worked towards developing a culture-specific visual language, which instilled a sense of national identity in their respective nation-states when many of these states were shaking off colonial rule and asserting their independence. They adopted the same name as the Hurufi, an approach of Persian Sufism which emerged in the late 14th–early 15th century. Art historian Sandra Dagher has described Hurufiyya as the most important movement to emerge in Arabic art in the 20th century.
