After the Six-Day War in 1967, it became increasingly difficult for archaeologists to use the British School of Archaeology in Jerusalem (BSAJ) as base for conducting fieldwork in neighbouring countries. In response, the BSAJ established a store of field equipment in Jordan. In the early 1970s the Director of the BSAJ, Crystal Bennett, conducted excavations in southern Jordan using this store and her private flat in Amman. However, the need for a larger and more permanent base became apparent when Bennett was asked by the Jordanian Department of Antiquities to direct major excavations of the Amman Citadel. She rented a large house opposite the University of Jordan and established it as the new British Institute at Amman for Archaeology and History (BIAAH) in 1975. Bennett served as both the Director of the BSAJ and the BIAAH until 1978, when she retired from the BSAJ and relocated to Amman full-time. In the same year, the British Academy agreed to register the BIAAH as an official overseas institute.
