The Nigerian ethnic group most closely associated with Uli body painting is the Igbo people of southeastern Nigeria. Uli is a traditional art form in which women use natural dyes - particularly the dark juice from the seeds of the Uli tree - to paint flowing, curvilinear designs on the skin. These body paintings were created for ceremonies, festivals, title-taking occasions, and other important social events.
Uli was not limited to body decoration. Igbo women also applied Uli motifs to the walls of buildings, especially homes and shrines. The designs drew on a rich vocabulary of symbols inspired by natural forms such as plants, snakes, the moon, and stars, each carrying cultural meaning within Igbo society.
The Hausa people of northern Nigeria are known for distinct artistic traditions such as leatherwork, embroidery, and geometric architectural decoration, but not Uli. The Tiv of central Nigeria have their own body scarification traditions (cicatrisation), which differ from Uli painting. The Ibibio of southeastern Nigeria are renowned for masquerade traditions and Ekpo masks rather than Uli. Uli remains a distinctly Igbo art tradition.
