At the beginning of the twentieth century, Dr H.R. Hall of the British Museum arrived at Ur to map the site and begin excavation.
This work was continued in 1922 when Leonard Woolley was appointed director of excavations. His work revealed a great deal about early Mesopotamian history, life and culture.
Around the same time, German archaeologists, led by Robert Koldewey, began to excavate the site of Babylon which shed more light on the history of this famous city.
