By the 16th century, towns like Prizren, Skopje, and Đakovica had established centers of learning that became crucial in inspiring and educating scholars who would then use their knowledge to benefit the Ottoman Empire and the Muslim world. From this time onward, many books circulated in the region that had a Persian influence while written in the Albanian language and Arabic alphabet.
