During the first decades after the eventual Fatimid conquest of Egypt in 969, the main naval enemy remained the Byzantines, but the war was fought mostly on land over control of Syria, and naval operations were limited to maintaining Fatimid control over the coastal cities of the Levant. Warfare with the Byzantines ended after 1000 with a series of truces, and the navy became once more important with the arrival of the Crusaders in the Holy Land in the late 1090s.
