Which Liberian people created their own alphabet?

The Vai people, who inhabit northwestern Liberia and parts of Sierra Leone, are the group known for creating their own writing system.12

In the 19th century, a Vai man named Doalu Bukere invented a unique syllabic script for the Vai language. This system is recognized as one of the few indigenous scripts in Africa. While the script is still used today, it is primarily utilized by older members of the community, as many Vai people are also literate in Arabic or English.132
