Medieval Azerbaijani refers to the form of the Azerbaijani language spoken and written during the medieval period, particularly from the 11th to the 15th centuries. This language evolved from the Oghuz branch of the Turkic languages and was influenced by Persian and Arabic due to cultural exchanges in the region. During this time, notable literary figures such as Nizami Ganjavi and Fuzuli contributed to the richness of Azerbaijani literature. The language served as a medium for poetry, prose, and historical texts, reflecting the social and cultural dynamics of Azerbaijan during the medieval era.
