When introducing this survey, it is necessary to say a word of justification about the time limits adopted. The year 1500 has been selected as an approximate starting point, because only during the reign of Sultan Bayezid II (1481-1512) do Ottoman tax registers become frequent enough to allow even approximate conclusions with respect to agricultural production. However when dealing with certain regions of the Empire, we need to adopt an even later starting point. After all, part of this paper deals with ‘Syria’ in the broad sense of the word, that is, the region bordering the eastern Mediterranean between Anatolia and Egypt; and this area was only conquered by the Ottomans in 1516. As to Tunisia, to which the present paper will also refer, this country only became part of the Ottoman Empire in 1533 or 1570.
