On the other side, the West Bank was annexed into Jordan, the subdistrict was merged with Ramallah Subdistrict to form Jerusalem Governorate, one of three Jordanian governorates in the West Bank.

Allar or 'Allar el-Fawqa, also known as 'Allar el Busl, was a Palestinian Arab village located southwest of the Old City of Jerusalem near Wadi Surar, along Wadi Tannur. The name was shared by the twin village of Allar al-Sifla or Khirbat al-Tannur, with official imperial ledgers often listing them both under the single entry of Allar.
