[3] Two Greek Orthodox monasteries were first established during the Byzantine period in the late fifth century, and are now standing within the municipal jurisdiction of Ubeidiya.

[3] ARIJ states that Ubeidiya was settled in 1600 by people originating from the Arabian Peninsula, its name evoking a certain Al-‘Ubeidi Faris of the Shammar tribe who came from Arabia.

They paid a fixed tax-rate of 33,3 % on agricultural products, including wheat, barley, occasional revenues, goats and/or beehives; a total of 4,900 akçe.

[9] In 1863, the French explorer Victor Guérin visited the place, which he called Deir Dosi, and described the remains of the monastery.

[12] Schick notes that in 1897, the Greek Orthodox Church had recovered the ruins of the former convent of Saint Theodosius from the Bedouin, and by the following year had started with their project of erecting a new monastery there.

[13] In the 1922 census of Palestine, conducted by the British Mandate authorities, the tribal area of Ibaidiyeh had an all-Muslim population of 2,000, 880 males and 1,120 females.

[24] The residents are mostly descendants of the Shammar[citation needed] with the main families being al-'Asa, al-Radayda, al-Rabai'a, al-Hasasna, and Abu Sirhan.

[25] The Greek Orthodox Monastery of St. Theodosius stands on a hilltop on the road to Mar Saba, some 6 km from the eastern outskirts of Bethlehem.

[3] The once large fortified Byzantine monastery, which holds the tomb of its founder, Saint Theodosius the Cenobiarch (c. 423–529),[3] has been rebuilt on a much smaller scale.
