Ziamet

Ziamet was an Ottoman land grant given to a person in return for military service. The sultan provided land or income to reward loyalty and keep troops ready, starting under Osman I and expanding under Murad I for the Sipahi cavalry. The idea wasn’t new to the region—the Seljuq state used similar grants to run provinces and militaries, and the Ottomans adopted this system after conquering Anatolia. They also carried forward a broader practice called the timar system, which the Seljuks used and the Ottomans later developed further.

In the 16th and 17th centuries, when central government control weakened, ziamets were enlarged and given to fewer owners for longer periods. This reduced local administrations and turned many ziamets into tax-farms (iqta). The result was stronger provincial governors who could challenge central authority as the empire’s economy declined.

How it worked: the ziamet holder, or zaim, acted as the central government’s agent in supervising land, its transfer and rental, and tax collection, in return for military service. A timar didn’t have to be one single block of land; it could be scattered across villages. A zaim is simply the holder of a timar. A zeamet was a higher level within the timar system, with annual tax revenue of 20,000 to 100,000 akçes.
