We get information about the Islamic Countries of the Middle Ages from 600 to 1200 AD for the Chronicles, semi-historical biographies, documents . of the words and deeds of the Prophet and from the interpretations of the Quran. All these were prepared from eye-witness descriptions. Each note of the eye-witness was examined through critical methods and only after ensuring its veracity and the authenticity of the author it was accepted for inclusion in the documents.
Most of the Chronicles and semi-historical biographies are written in Arabic. The best of them is Tareekh-al-Tabari. This is translated into English in 38 volumes. Although the number of Persian Chronicles are few, there are detailed descriptions about Iran and Central Asia. It was only in the 19th century, proper histories of Islam began to be written. Professors in Germany and Netherlands were the ones who initiated this project.
