The Battle of Manzikert, or Malazgirt, was fought between the Byzantine Empire and Seljuq forces led by Alp Arslan on August 26, 1071 near Manzikert (modern Malazgirt in Muş Province, Turkey). It resulted in one of the most decisive defeats of the Byzantine Empire and the capture of the Byzantine Emperor Romanos IV Diogenes. The Battle of Manzikert played an important role in breaking the Byzantine resistance and preparing the way for Turkish settlement in Anatolia.
The battle marked the high point of the initial Turkish incursions and was followed up two years later with a large influx of Turkish settlers and soldiers, many at the request of the crumbling Byzantine Empire. However, the battle was not the slaughter that many historians, including contemporary writers, have stressed it to be — large numbers of mercenaries and Anatolian levies fled and survived the battle, thanks in part to Alp Arslan's refusal to pursue them. All the Byzantine commanders, including Romanos, survived to participate in the numerous civil conflicts that wrecked Anatolia. Nonetheless, the Byzantine Empire would never again be able to muster a force as large, nor as distantly projected, as that which took part in the fateful battle.
