Abstract
<jats:p>Türkiye-Azerbaijan relations, which have been steadily progressing, took a significant leap forward with the Shusha Declaration, elevating them to an alliance and creating a new geopolitical reality for both countries, the region, and the Turkic world. The Declaration initiated a process of deepened cooperation in military, security, economic, and political spheres. During this period, these strengthened ties began to significantly influence the South Caucasus, fostering increased regional stability and enabling stronger economic and security networks that extend to the broader Turkic world. This chapter examines the momentum of Türkiye-Azerbaijan relations following the Shusha Declaration, highlighting aspects that directly contribute to regional stability, connectivity, and integration within the Turkic world.</jats:p>
