Final answer:
Southeastern Turkey is part of the homeland of the ethnic Kurds, who make up a significant portion of Turkey's population and have sought recognition for their cultural region known as Kurdistan.
Step-by-step explanation:
Southeastern Turkey is part of the homeland of the minority ethnic group known as the Kurds. This region, also referred to as Eastern Anatolia, is where many Kurds have advocated for autonomy or independence, forming a region they call Kurdistan. The Kurdish population in Turkey is significant, making up around 19 percent of the country's total population, with many living in this southeastern part of the country, including the city of Diyarbakir, which is considered the cultural capital of the Kurdish people in Turkey. Despite their distinct language, culture, and history, the Kurds have faced challenges in gaining political recognition and autonomy.
