In the British Mandate of Palestine- period, the village was classified as a hamlet in the Palestine Index Gazetteer.[6] In the 1922 census of Palestine Wadi Arah had a population of 68; all Muslims,[10] increasing in the 1931 census to 81; still all Muslim, in a total of 18 houses.[11]

During the 1948 Arab-Israeli War the village was successfully defended by Arab Liberation Army volunteers and Iraqi forces patrolling the nearby city of Tulkarm. However, locals in the area experienced violence at the hands of Israeli forces; A member of kibbutz Be'eri, assigned to the Guard Milices testified in a study undertaken by Israeli historian Yitzhaki and Uri Milstein: "We were in Wadi 'Ara. We raided a nearby Palestinian post and brought a prisoner for interrogation. A soldier beheaded him and scalped his head by knife. He raised the head on a pole to strike fear among Palestinians. Nobody stopped him."[15] Most non-Jewish residents were removed on February 27, 1948 prior to the official founding of the modern state of Israel, those remaining were removed by the end of July 1949.

In March 1949 as the Iraqi forces withdrew from Palestine and handed over their positions to the smaller Jordanian legion, three Israeli brigades manoeuvred into threatening positions in Operation Shin-Tav-Shin in a form of coercive diplomacy. The operation allowed Israel to renegotiate the ceasefire line in the Wadi Ara area of the northern West Bank in a secret agreement reached on 23 March 1949 and incorporated into the General Armistice Agreement. The green line was then redrawn in blue ink on the southern map to give the impression that a movement in the green line had been made.[16] Jordan ceded the entire Wadi Ara region to Israel on May 3, 1949.

Following the area's incorporation into Israel, kibbutz Barkai was established on the site of Wadi Ara on May 10, 1949.[12] In 1992 Palestinian historian Walid Khalidi described the remaining structures on the village land: "Only two village houses remain, both on the eastern edge of the site. One of them has arched windows and a spiral staircase leading up to a room on the roof. The second has a large entrance that is used today as a gate for the kibbutz's swimming pool."[12]

Petersen inspected the remaining buildings in 1994, and described them as "a large rectangular building which appears to be of late Ottoman date. On the ground floor is a long hall (18.8m x 6.9m) roofed by three cross-vaults. On the upper floor is a large terrace and a single cross-vaulted room. South of this building are the remains of a high wall and a monumental gateway which now gives access to the Kibbutz swimming pool. It is likely that both buildings date to the latter part of the Ottoman period (i.e. 1880-1917)"[17]
