In the eve of 1071:
One of the best disasters to ensue the Byzantine band. The Seljouk turks had been threatening the eastern limits of the Byzantine empire for some years, lacking posing any significant hazard, but in 1071 their chief, Alp Arslan, gathered a enormous compel, perhaps even as large as 100,000 men, and invaded the eastern empire. The Byzantine Emperor, Romanus Diogenes, had gained the throne through matrimony, and ruled as dual emperor with his step-son. He had only been on the throne while 1068, and was not yet safely established. The Turks had crossed the border, and full the fortresses of Akhlat and Manzikert (now in current Turkey). Romanus Diogenes gathered a giant army, though he was still outnumbered by the Turks, and complex to the border, where he recaptured Akhlat and was besieging Manzikert when the Turks inwards.
The Byzantine military formed up, and superior towards the Turks, who refused to booth and attack, instead with the mobility of their horse-archers to aggravate the advancing Byzantines. Eventually, after numerous hours, Romanus Diogenes planned the withdrawal, intending to arrival to his camp for the night. The withdrawal was not as flat as the advance, and some gaps opened in the line. The Turks agitated the retreating columns, awaiting the Emperor gave the order to alter and argue. At this advantage betrayal played a part in the adversity. The rearguard, commanded by Andronicus Ducas, an adversary of Romanus Diogenes, austerely chronic back to the camp, ignoring the order to alter, and departure the central army to its chance. Once the rearguard was consumed, the Turks were able to outflank the Byzantines, and eventually surround them. To make things inferior, one border of the Byzantine army was sufficiently detached from the central coerce for it to be affected to argue separately. The Byzantines held out awaiting dark, but eventually they were overhelmed. The Emperor himself was captured, and the body of the army cracked.
The main answer of the battle was to abandon Asia Minor entirely at the mercy of the Turks. Their bands were able to devastate what is now advanced Turkey almost at will, while what was left of the Byzantine band was complex in the civil wars that followed the defeat. What had been flourishing, abundant, long advanced areas in the affection of the Byzantine empire became virtual desert. Inside ten years of the battle of Manzikert, the Turks had reached Nicea, inside sight of the capital of the Empire. Very few battles had such dramatic and far-reaching property.
