The Vai are Mandé peoples that live mostly in Liberia, with a small minority living in south-eastern Sierra Leone. The Vai are known for their indigenous writing system known as the Vai syllabary, developed in the 1820s by Momolu Duwalu Bukele and other Vai elders. Over the course of the 19th century, literacy in the writing system became widespread. Its use declined over the 20th century, but modern computer technology may enable a revival.

The Mandé people are an ethnic and linguistic group who are native to West Africa, possessing a long shared history and forming a distinct linguistic family known as the Mandé Languages. The Mandé languages are divided into two primary groups: East Mandé and West Mandé.
