The present city of Juba was established on the site of a small Bari village,  also called Juba, where the Church Missionary Society (CMS) had established a mission and the Nugent Memorial Intermediate School in 1920–21.  In the late 1920s, Anglo-Egyptian officials ordered Bari residents to relocate so that a new town could be constructed to serve as the capital of Mongalla Province.  The site was chosen by Anglo-Egyptian officials partly because of the presence of the CMS Nugent Memorial Intermediate School there, and partly because its proximity to river transportation on the Nile.  Major construction of the new city of Juba was underway by 1927.  Traders from Rejaf relocated to the new city in 1929, and the Governor's office of Mongalla was moved there in 1930.
