The Greeks had little spirit to fight, and the emperors took some of these stout Northmen into their pay against the Bulgarians and Saracens, calling them their Varangian Guard.  Another band, of northern blood, though they had been settled in Normandy for two generations, came, and after driving out the Saracens from Sicily and Southern Italy, set up two little kingdoms there.  Robert Guiscard, or the Wizard, the first and cleverest of these Norman kings, had a great wish to gain Greece also, and had many fights with the troops of the Emperor of the East, Alexis Comnenus.  Their quarrels with him made the Greeks angry and terrified when all the bravest men of the West wanted to come through their lands on the Crusade, or Holy War, to deliver Jerusalem from the Saracens. Then, since the schism between the Churches, the Greeks and the Latins had learnt scarcely to think of one another as Christians at all, and certainly they did not behave to one another like Christians, for the Greeks cunningly robbed, harassed, and deceived the Latins, and the Latins were harsh, rude, and violent with the Greeks.
