Qusin

Qusin, 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 liwa ("district") of Nablus. The village had a population of 15 households and 7 bachelors, all Muslim. The villagers paid a fixed tax-rate of 33,3% on agricultural products, such as wheat, barley, summer crops, beehives and/or goats, in addition to occasional revenues and a customary tax for people of Nablus area; a total of 6,300 akçe.[6]

In 1882, in the PEF's Survey of Western Palestine, Kusein was described as: "A village on the side of a ridge, apparently supplied by the water of the valley on the north, which has a flowing stream. A spring exists about three-quarters of a mile south-east in the valley."[7] They further noted that: "The ruin shown near this place is merely a heap of stones."[8]

In the 1922 census of Palestine conducted by the British Mandate authorities, Qusen had a population of 147 Muslims,[9] increasing in the 1931 census to 217 Muslims, in 48 houses.[10]

In the 1945 statistics, Qusin had a population of 310 Muslims[11] while the total land area was 4,543 dunams, according to an official land and population survey.[12] Of this, 59 dunams were used for plantations and irrigable land, 3,227 for cereals,[13] while 21 dunams were classified as built-up areas.[14]

In the wake of the 1948 Arab–Israeli War, and after the 1949 Armistice Agreements, Qusin came under Jordanian rule.

The Jordanian census of 1961 found 494 inhabitants.[15]

After the Six-Day War in 1967, Qusin came under Israeli occupation.

After the 1995 accords 51% of village land is defined as Area B land, while the remaining 49% is defined as Area C. Israel has confiscated about 500 dunham of village land for future expansion of Israeli settlements, and additional land for Israeli bypass roads.[16]
