from the Iron Age and Byzantine eras have been found here. This place has earlier been identified with the Crusader place called Caphrapalos, however that is not an identification which Finkelstein accepts.
A shard from the early Ottoman era was found, but Finkelstein finds the identification "questionable." The modern village was re–founded in the 18th century. Prior to becoming a permanent settlement, it was khirba i.e. a temporary settlement. Khirbet Abu Falah became a permanent village when the Jaradat and Shu'man clans moved there from al-Mazraa al-Sharqiya as a result of a dispute with other clans in that village. The village was named after one of its leaders, Abu Falah. In 1838 Abu Felah was noted as a Muslim village, part of the Beni Salim district, located east of Jerusalem. An Ottoman village list from about 1870 showed the village, called Chirbet abu-fellah, had a population of 265, with a total of 58 houses, though the population count only included men. It also noted it was located SE of Turmus Ayya. In 1882, the PEF's Survey of Western Palestine described it as: "a small hamlet on high ground, with ruins." They further noted, that it: "appears to be an ancient site; cisterns and an ancient birkeh, partly of good-sized masonry and partly cut in rock, exist here, with foundations. The place is still inhabited." In 1896 the population of Chirbet abu felah was estimated to be about 816 people.
In the 1922 census of Palestine conducted by the British Mandate authorities, the village had a population of 519, all Muslims, increasing slightly in the 1931 census where Khirbet Abu Falah had a population of 588, in 125 houses. In the 1945 statistics the population was 710, all Muslims, while the total land area was 8,186 dunams, according to an official land and population survey. Of this, 3,080 were allocated for plantations and irrigable land, 1,615 for cereals, while 19 dunams were classified as built-up areas.
Since the Six-Day War in 1967, Khirbet Abu Falah has been under Israeli occupation. After the 1995 accords, 99.7% of village land was classified as Area B, the remaining 0.3% as Area C. In 1998, a village council was established to administer Khirbet Abu Falah's civil affair. The council has nine members appointed by the Palestinian National Authority. The council is also included in the Joint Services Council, which is a cooperative board that also includes the villages of al-Mazraa al-Sharqiya, Kafr Malik and al-Mughayyir.
