The author of Kanun-ı ‘Osmânî mefhûm-i defter-i hakanî (“The Ottoman laws i.e. the content of the imperial register”) starts stating that he wrote his treatise because issues such as which kind of tax should be paid for lands, or whether those who have the usufruct of a plot have also its freehold property, were unknown and unspecified; so he decided to describe all matters pertaining to villages, peasants, landholding and land taxation in the domains “inserted in general to the circle of justice and belonging in the territory of [the Sultan’s] full dominion” (U384: havza-i hükûmet-i tam ve daire-i adalet-i âmlarında münderic olan memâlik). Then he explains in detail the landholding system (U384-86; this section, including the introduction above, is copied almost verbatim from the kanunname of Sivas, compiled in 1578, a few years after Ebussuud’s death: Akgündüz, Osmanlı kanunnâmeleri, vol. 8, 425-27), starting from a historical account on the creation of the two categories (arz-ı haraciyye, arz-ı memleket) and explaining that in the second case, which in the Ottoman central lands (vilâyet-i Rumeli ve öte yakada vâki eyâletlerin) is called miri, the substance of the land (rakabe) belongs to the treasury (rekabe-i arz beytülmal-i müslimin için alıkonulup). Avnî Ömer enumerates then the land categories in the Ottoman Empire, i.e. the various kinds of fiefs, the lands granted as mülk by the Sultan, the vakf lands, the Christian timars, and so forth, noting the tax status of each and the obligations of their holders.
In the unpublished part of the treatise, the author gives an alphabetical list of the kazas in Anadolu and Rumili (Gökbilgin, “XVII. Asırda Osmanlı devletinde ıslâhat ihtiyaç ve temayülleri”, 212).
