The Bamum scripts are an evolutionary series of six scripts created for the Bamum language by Ibrahim Njoya, King of Bamum (now western Cameroon). They are notable for evolving from a pictographic system to a semi-syllabary in the space of fourteen years, from 1896 to 1910. Bamum type was cast in 1918, but the script fell into disuse around 1931. A project began around 2007 to revive the Bamum script.
The Bamum script is also used to write the Shümom language, also invented by Njoya.
