SWP noted: "The ruin west of the village has the appearance of an ancient site. Foundations,
cisterns cut in the rock, and heaps of stones among bushes."[5]
Sir is identified with Kfar Zir (
Hebrew: כפר ציר), mentioned in the 6th-7th century
Mosaic of Reḥob as a
Jewish village in the region of
Sebastia inhabited mostly by non-Jews and, therefore, agricultural produce obtained from the area could be taken by Jews without the normal restrictions imposed during the
Sabbatical years, or the need for
tithing.[8]
A
Crusader estate named Casale Syrorum, whose rights were affirmed in the year 1165/1166 CE by
Amalric of Jerusalem, was located here.[9][10]
Ottoman era
Sir, like the rest of
Palestine, was incorporated into the
Ottoman Empire in 1517, and in the
census of 1596 it was a part of the nahiya ("subdistrict") of Jabal Sami which was under the administration of the
Nablus Sanjak. The village had a population of 31 households and 4 bachelors, all
Muslim. The villagers paid a fixed tax-rate of 33,3% on agricultural products, such as wheat, barley, summer crops, olive trees, beehives and/or goats, in addition to occasional revenues, a tax for people of liwa Nablus, and a press for olive oil or grape syrup; a total of 7,832
akçe.[11]
In 1870,
Victor Guérin noted it as a small village on a high hill. There were many cisterns and tombs cut out from the rock, which convinced Guérin that the place was ancient. The inhabitant, which numbered 150, had a
mosque.[12]
In 1882, the
PEF's Survey of Western Palestine (SWP) described Sir as: "A small village on a knoll amid brushwood, with a large house on the west."[13]
In the
1945 statistics the population of Sir was 290, all Muslims,[16] with 12,499
dunams of land, according to an official land and population survey.[17] Of this, 1,908 dunams were used for plantations and irrigable land, 6,045 dunams for cereals,[18] while 10 dunams were built-up (urban) land and 4,536 dunams were classified as "non-cultivable".[19]
