How did the Seljuq invasions change Armenia in the 11th century?

By the 11th century, the Armenian kingdoms had already been weakened and largely dismantled by the Byzantine Empire, which annexed various territories and seized the capital, Ani, in 1045.1

The subsequent Seljuq invasions fundamentally altered the region:

• Military Conquest: Following the first raid in 1048, Seljuq forces under Alp-Arslan captured Ani and Kars in 1064. The decisive Battle of Manzikert in 1071 shattered the Byzantine frontier, placing most of Armenia under Seljuq control.123
• Political Fragmentation: While some native Armenian rulers survived in smaller principalities like Lori, Kapan, and Khachen, the broader political structure was transformed. In 1072, Ani was granted as a fief to the Kurdish Shaddadids.1
• Demographic and Regional Shifts: The invasions facilitated the settlement of Turkmen tribes in the region, and by the 12th century, many former Armenian territories were incorporated into Georgia.1

Despite these upheavals, Armenian cultural and religious life persisted, centered primarily around monasteries and village communities.1
