The vicinity of Qalqilya has been populated since
prehistoric times, as attested to by the discovery of prehistoric
flint tools.
Ottoman period Qalqilya appeared in
Ottoman tax registers (transliterated as
Qalqili) in 1596, as a village in the
nahiya (subdistrict) of Bani Sa'b in the
Liwa of
Nablus. It paid a total of 3,910
akçe in taxes on wheat, barley, summer crops, olives, and goats or beehives. Modern qalqilya began as a daughter village of
Baqa al-Hatab in the West Bank.
Edward Robinson described
Kulakilieh in 1838 as a village in ''Beni Sa'ab
district, west of Nablus. An Ottoman census listed the village in the nahiya'' (sub-district) of Bani Sa'b, in . Qalqilya was described in 1882 as "a large somewhat straggling village, with
cisterns to the north and a pool on the south-west. The houses are badly built." Residents from nearby
Baqat al-Hatab move to the city in 1883, and a municipal council to administer Qalqilya was established in 1909.
British Mandate period An official land survey recorded 27,915
dunams of land owned in 1945. Of this, 3701 dunams were for citrus and bananas, 3,232 were plantations and irrigable land, 16,197 used for cereals, while 273 dunams were built-up (urban) land. According to
Sami Hadawi, the town had been "one of the most prosperous in Palestine, owning extensive orange groves and serving as one of the main vegetable markets of the country."
1948 War During the war, many inhabitants from
Kafr Saba,
Abu Kishk,
Miska,
Biyar 'Adas and
Shaykh Muwannis resettled in Qalqilya. Residents of Qalqilya who left during the fighting returned with the arrival of the
Jordanian Arab Legion and the Iraqi expeditionary force, apart from 2,000 upper-class residents who settled in
Nablus for economic reasons. Hadawi argues that the
armistice lines established in 1949 "severed all [Qalqilya's] orange groves in favour of Israel," leaving the town "landless except for its rocky areas towards the east." among other incidents. The attack was ordered by
Moshe Dayan and involved several thousand soldiers. During the fighting, a paratroop company was surrounded by Jordanian troops and escaped under close air-cover from four
Israeli Air Force aircraft. Eighteen Israelis and 70 to 90 Jordanians were killed in the operation.
Post 1967 In the wake of the
Six-Day War in 1967, Qalqilya came under
Israeli rule. Dozens of inhabitants were expelled to
Jordan as part of the Palestinian expulsions of 1967 known as the
Naksa. 850 buildings were razed. After the IDF's psychological warfare unit made a visit to the city and many of the residents had fled, the UN representative Nils-Göran Gussing noted that 850 of the town's 2,000 houses were demolished. In his memoirs,
Moshe Dayan wrote that these actions ultimately constituted "
collective punishment" which was contrary to government policy. The villagers were eventually allowed to return and the reconstruction of damaged houses was financed by the military authorities. As part of the 1993
Oslo Accords between Israel and the
Palestine Liberation Organization (PLO), control of Qalqilya was transferred to the
Palestinian National Authority (PNA) on 17 December 1995. In 2003, the
Israeli West Bank barrier was built, encircling the town and separating it from agricultural lands on the other side of the wall. In November 2015, Israel arrested what it alleged to be a network of 24
Hamas militants active in the city. On 20 October 2017, the municipality of Qalqilya named a street after
Saddam Hussein and erected a memorial with his likeness. The monument was unveiled at a ceremony attended by the Qalqilya District Governor Rafi Rawajba and two other Palestinian officials. It bears the slogan "Saddam Hussein – The Master of the Martyrs in Our Age". On 19 June 2022, a 53-year-old Palestinian was shot and killed by Israeli forces as he sought to cross the
Israeli West Bank barrier, which encircles Qalqilya. According to the IDF, he damaged the security fence in an attempt to cross into Israeli territory. It's unclear whether he was armed. On 22 June 2024, a 60-year-old Israeli citizen was shot dead in Qalqilya by local residents. The victim, from Petah Tikva, regularly bought vegetables in the city. Following the shooting, his car was set on fire, and his personal documents were taken. This incident was the third in Qalqilya within 48 hours, following another attack on Thursday, where a 70-year-old Israeli was killed, and the elimination of two
Islamic Jihad operatives who planned an attack. ==Geography==
