Step-by-step explanation:
The Kurdish ethnic group is the largest nation of people in the world without a country, with about 25 million Kurds living in the Middle East. The majority of Kurds, about 14 million, live in Turkey, while others reside in Iran, Iraq, and neighboring countries. The Kurds have their own language, history, and customs, and they originated from northern Europe centuries ago. Many Kurds have converted to Islam, and within the Kurdish ethnic group, both Sunni and Shia Islam are practiced. Kurdish nationalists advocate for the establishment of a new nation-state called Kurdistan, but their aspirations have been met with resistance from the governments of Syria, Turkey, Iraq, and Iran.
