Turkey has played a complex and controversial role in the conflict between Azerbaijan and Armenia. The conflict centres on the disputed region of Nagorno-Karabakh, which is internationally recognized as part of Azerbaijan but has been controlled by ethnic Armenian separatists since the 1990s.

Turkey has long-standing ties with Azerbaijan, including a shared language and cultural heritage, and it has traditionally been a strong ally of Azerbaijan. During the conflict, Turkey provided military, political, and economic support to Azerbaijan and has publicly backed Azerbaijan's position.

Turkey's support for Azerbaijan has been a source of tension with Armenia and other countries. It has been criticized for fueling the conflict and its role in the 2020 Nagorno-Karabakh war. Turkey has also faced accusations of involvement in the competition from the Armenian side, including allegations of sending fighters and weapons to the region.

Overall, Turkey's role in the conflict between Azerbaijan and Armenia has been controversial and complex and has drawn international attention and criticism.
