Who Are the Kurds? VOA News The Kurds' involvement in the conflict in Syria is complicated, because of the group's troubled history that spreads across several regional borders. Here is a look at the current Kurdish crisis and how it came to be. Who are the Kurds? The Kurds are one of the indigenous people of the Mesopotamian plains and the highlands, areas that today are contained within southeastern Turkey, northeastern Syria, northern Iraq, northwestern Iran and southwestern Armenia. Estimated at between 25 million and 35 million people, the Kurds are the fourth-largest ethnic group in the Middle East. They form a distinctive community, united through race, culture and language, and while most of them are Sunni Muslims, they also adhere to a number of different religions and creeds, including Christians, Jews, Yazidis and Zoroastrians. They are considered the largest ethnic group in the world to be stateless. Why don't they have a country? After World War I and the defeat of the Ottoman Empire, the victorious Western allies made provision in the 1920 Treaty of Sevres for the formation of a Kurdish state, to be known as Kurdistan. But their hopes were dashed three years later when the Treaty of Lausanne, which set the boundaries of modern Turkey, made no provision for a Kurdish state and left Kurds with minority status in four countries -- Turkey, Syria, Iraq and Iran. Over the next 80 years, any move by Kurds to set up an independent state was quashed. After the firstGulf War, followed by a Kurdish uprising in northern Iraq and the establishment of a no-fly zone, the Kurds managed to establish a semiautonomous region. The second Gulf War, which ousted Saddam Hussein, enabled them to consolidate those gains in a largely autonomous region across northern Iraq. In recent years, the fight against the Islamic State terror group has presented an opportunity for the Kurds to further project legitimacy on the international stage. .
