Among global separatist movements, the Kurds stand as the largest nation without an independent state and make up the fourth-largest ethnic group in the Middle East, according to BBC News. There is an estimated population of 30 million Kurds scattered across the mountainous regions within the borders of Armenia, Iran, Iraq, Syria, and Turkey. The Kurds often say that they have “no friends but the mountains.” The Economist also reports that “internal division has been one of their worst enemies.”
