In 717 a huge Arab army and fleet laid siege to Constantinople. Emperor Leo III beat off the assault, Greek fire burned the ships, and a harsh winter, hunger and Bulgar attacks wore down the besiegers, who withdrew in August 718. The victory halted the caliphate's advance into Europe from the east for centuries.
