How did the people of Mali communicate through writing?

The people of Mali primarily communicated through writing using the Arabic script, which was introduced through trade and the spread of Islam. In addition to Arabic, the Manding languages were represented using the N'Ko script, developed in the 1940s to promote literacy among speakers of these languages. Written communication included religious texts, trade documents, and historical accounts, reflecting the rich cultural heritage of the region. These methods of writing facilitated both local and transcontinental interactions.
