Although the term Ottoman Archives should in fact include any archive that once fell within the boundaries of the Ottoman Empire, it only reminds us of the Başbakanlık (Primeministerial) Archives and that of Topkapı Palace in Istanbul. Furthermore the Ottoman archival material whether found in the National Archive of Cairo or in Ragusa Archive of Yoguslavia are of no lesser importance than those found in Başbakanlık Archive although not as abundant. The scholars of the Balkan states such as Albania, Bosnia, Bulgaria and Hungary have not only taken interest in the Ottoman archives in their own countries, but also in the Primeministerial Archive of Istanbul, and have studied and published many documents -especially the ones pertaining to their own countries- from these archives. Unfortunately the Turks and the Arabs have only recently started taking interest in these archives and particularly the Arab scholars in this field are very scant. There is no doubt that these archives are not only important for the Muslim countries but also for the world history. The report prepared by Unesco in 1982 makes this point very clear.

The sancak of Amid (today known as Diyarbakır) has been ruled by the Byzantines, Arabs, Selçukids, Artukids, Ayyubids, Akkoyunlus and Ottomans. Therefore the sancak has been exposed to the cultures of these states. Thus the province had undergone a great cultural impact which can clearly be traced in the personal and place names used in the sancak. The place and personal names recorded in the 1518 Ottoman cadastral survey of the sancak of Amid are the basis of some pointers made in this article.

The sources and literature on the medial history of Diyarbekr region are limited as it is the general case with the medieval history of Anatolia on the whole. Apart from few sources which are, however, directly related to the area there are othere sources from which indirect infirmation can be derived to study the history of the area. Inorder to avoid confusion, however, no such classification will be made, rather they will be treated under original or primary sources, secondary literature and Armenian and Syriac sources. Before examining them, nevetheless, it would perhaps be better to briefly mention few works and bibliographies in which there can be found a good literature on the area.

The historical importance of the Eastern Region of Saudi Arabia can never be denied; Al-Hasa may have the fame as an oasis, but Katif as part of it is of no less importance. The territory of Katif is divided from Al-Hasa province by an intervening range of hills, the most famous of which is know as Jabal Mushahhar. This hill, seven hundred feet high, falls about ten miles to the south of Katif.
