THEME T HEMES IN W ORLD H ISTORY in Arabic, the best being the Tarikh of Tabari (d. ) which has been translated into English in volumes. Persian chronicles are few but they are quite detailed in their treatment of Iran and Central Asia. Christian chronicles, written in Syriac (a dialect of Aramaic*), are fewer but they throw interesting light on the history of early Islam.
Besides chronicles, we have legal texts, geographies, travelogues and literary works, such as stories and poems. Documentary evidence (fragmentary pieces of writing, such as official orders or private correspondence) is the most valuable for writing histories because it does not consciously refer to events and persons. It comes almost entirely from Greek and Arabic papyri (good for administrative history) and the Geniza records. Some evidence has emerged from archaeological (excavations done at desert palaces), numismatic (study of coins) and epigraphic (study of inscriptions) sources which is of great value for economic history, art history, and for establishing names and dates.
Proper histories of Islam began to be written in the nineteenth century by university professors in Germany and the Netherlands. Colonial interests in the Middle East and North Africa encouraged French and British researchers to study Islam as well. Christian priests too paid close attention to the history of Islam and produced some good work, although their interest was mainly to compare Islam with Christianity. These scholars, called Orientalists, are known for their knowledge of Arabic and Persian and critical analysis of original texts.
Ignaz Goldziher was a Hungarian Jew who studied at the Islamic college (al-Azhar) in Cairo and produced path-breaking studies in German of Islamic law and theology. Twentieth-century historians of Islam have largely followed the interests and methods of Orientalists. They have widened the scope of Islamic history by including new topics, and by using allied disciplines, such as economics, anthropology and statistics, have refined many aspects of Orientalist studies. The historiography of Islam is a good example of how religion can be studied with modern historical methods by those who may not share the customs and beliefs of the people they are studying.
