In response to Nasser's increasing attacks on Western colonialism and imperialism and Egypt's continued alliance with the Soviet Union, Britain and the United States withdrew funds for the Aswan Dam in July 1956. That action drove Egypt further toward an alliance with the Soviet Union and was a contributing factor to the Suez Crisis later in 1956. Nasser responded to the aid cut by nationalizing the
Aswan Low Dam in the lower Nile. The dam, originally limited in height by conservation concerns, worked as designed, but provided inadequate storage capacity for planned development and was raised twice, between 1907 and 1912 and again in 1929–1933. These heightenings still did not meet irrigation demands and in 1946 it was nearly over-topped in an effort to maximize pool elevation. This led to the investigation and construction of the Aswan High Dam upstream. The earliest recorded attempt to build a dam near Aswan was in the 11th century, when the Arab polymath and engineer Ibn al-Haytham (known as "Alhazen" in the West)
