Resm-i dönüm
The resm-i dönüm was a land tax in the Ottoman Empire; it was a divani tax paid each year to the landowner or timar holder, typically on 1 March. The resm-i dönüm was based on the dönüm, a measure of farm size; this is parallel to the resm-i çift, a tax based on the çift (the area that could be ploughed by one team of oxen).
