What happened
At Manzikert in Byzantine Armenia, the Seljuk sultan Alp Arslan destroyed an army led personally by Emperor Romanos IV Diogenes. Romanos fielded a force of conscripts and mercenaries, including Pechenegs, Uzes, and a Norman contingent under the unreliable Roussel de Bailleul. During the retreat a rival, Andronikos Doukas, spread a false rumor that the emperor had been killed, and the Byzantine line collapsed into a rout. Romanos, his horse killed under him and his sword hand wounded, was taken prisoner. The eyewitness chronicler Michael Attaleiates described the scene as being "like an earthquake," with the whole Roman army in flight and the empire itself seeming to teeter on collapse. Alp Arslan treated his prisoner with courtesy, even reportedly asking what Romanos would have done in his place, but the political fallout back in Constantinople was severe and the Anatolian frontier never fully recovered.
Why it matters
Manzikert opened Byzantine Anatolia, previously the empire's main recruiting ground and breadbasket, to permanent Turkish settlement and the rise of the Sultanate of Rum. The territorial and manpower losses that followed pushed Emperor Alexios I Komnenos, a generation later, to ask the West for military help, the appeal that Pope Urban II would answer at Clermont.
How we know
The main eyewitness account comes from Michael Attaleiates, a Byzantine official who accompanied the campaign, supplemented by the eleventh-century Scylitzes Chronicle's detailed narrative of Romanos's capture and treatment.
