In this pre-Ottoman period, timars were used with other tactics, such as building caravansaries, in an effort to sedentarize nomadic groups.
The Ottoman Empire came into disarray due to problems asserting "central government control" during the 16th and 17th centuries.
Ziamets of Ottoman cavalry were enlarged and turned over to a smaller number of owners, with a longer tenure.
The ziamet holder acted as an agent of the central Ottoman government in supervising the possession, transfer, and rental of lands within his territory, and collecting tax revenue, in return for military service.
A Zeamet was the appellative given to a land in the timar system during the Ottoman Empire between the 14th and 16th centuries, that had a tax revenue with an annual value between 20,000 and 100,000 akçes.
