For nearly 200 years, the Kurdish people have never had a truly independent state of their own. At a population of around 45 million today, that makes the Kurds one of the largest nations that does not have their own country. They are currently divided between the borders of Iran, Iraq, Syria, and Turkey, and about 15 million Kurds live within Turkey. From time to time over the centuries, there have been demands and calls from among the Kurds to establish their own separate country, but that call has perhaps been the loudest from within Turkey, where ever since the 1980's into the present day, the Kurdistan Worker's Party, or PKK, has waged a violent campaign of insurgency and terrorism against the Turkish state for independence that has claimed the lives of tens of thousands since it began. This is the story of Turkey's most horrible, enduring, and tragic modern conflict.
