The Khalaj people, one of the 24 Turkic tribes, are recorded in historical sources under the names Qalach, Khalch, Khulaj, and Qalch. Most historians consider them a branch of the Ghazis, who, after dispersing across East and Central Asia, managed to form an independent and distinct identity. This identity manifested not only in their social and political structures but also in their language and culture. The Khalaj language, referred to as “Ancient Turkic,” reflects the authenticity and cultural continuity of the Khalaj people due to its preservation of original Turkic vocabulary that is no longer used by other Turkic tribes. Persian and Arabic texts describe them as a nomadic and warrior people who played decisive roles in many significant historical battles, thereby contributing substantially to the formation of regional powers. Understanding the Khalaj language and ethnicity is particularly important for studies of cultural preservation, political influence within Turkic governments, the establishment of rule in India, and the promotion of the Persian language. In the past century, Turkologists such as Gerhard Doerfer, Minorsky, and Dr. Heyat have conducted detailed analyses of this tribe; however, the lack of independent historical sources has left ambiguities regarding their lineage, the origins of their name, and their lifestyle. This study, relying on credible historical sources, seeks to analyze and elucidate the identity, social and cultural position of the Khalaj, and their role in historical developments, aiming to partially fill the gaps in previous research and provide a more comprehensive understanding of this influential people.
