The reign of al Adil was generally more one of consolidation than of expansion. He was in his late fifties by the time he consolidated his power, and by that time had been almost constantly at war for two decades. His first concern was to rebuild his treasury, which had been left almost empty by his brother's empire-building, the wars with the Crusaders and the struggles within the Ayyubid dynasty itself. Al-Adil introduced reforms both to the currency and to the taxation system. The effectiveness of his measures can be judged from the relatively rapid recovery Egypt made from an earthquake in 1200 (597) and the low flooding of the Nile between 1199 and 1202 (595–98). The resulting drought and famine were serious threats, but by a range of measures including sending his soldiers out to work the land, al-Adil ensured continued social and political stability as well as economic recovery.
