Significance:
1. End of Byzantine Dominance: The Battle of Manzikert marked the end of Byzantine dominance in Anatolia. Prior to the battle, the Byzantines had controlled much of Anatolia, but after their defeat, the Seljuks were able to establish their control over the region.
2. Loss of Territory: As a result of the battle, the Byzantines lost a significant portion of their territory in Anatolia to the Seljuks. This loss of territory weakened the Byzantine Empire and contributed to its decline.
3. Rise of the Seljuk Turks: The victory at Manzikert allowed the Seljuks to consolidate their power in Anatolia and become a major regional power. The Seljuk Sultanate emerged as a major rival to the Byzantine Empire and posed a constant threat to Byzantine territory.
4. Internal Conflict: The defeat at Manzikert also caused internal conflict and instability within the Byzantine Empire. Emperor Romanus IV Diogenes was deposed and replaced by Michael VII Doukas, leading to a period of political turmoil and civil wars.
5. Norman Invasions: The decline of the Byzantine Empire after Manzikert also facilitated Norman invasions in the Balkans and Italy, further challenging the Byzantine Empire.
6. Catalyst for the Crusades: The loss of the Holy Land to the Seljuks after Manzikert was one of the factors that contributed to the launching of the Crusades by Western Europe in an effort to recapture the holy sites.
7. Long-Term Impact: The Battle of Manzikert had long-term consequences for the Byzantine Empire. It weakened the empire and contributed to its eventual fall in 1453, while also leading to the rise of the Ottoman Empire and the transformation of the political and demographic landscape of Anatolia.
