Which of the following ethnic groups in the Middle East has unsuccessfully tried to gain its own, independent state or country?

Arabs, Persians, Kurds, or Turks

The Kurds.

Explanation:

The Kurds are one of the indigenous peoples living in the south-eastern Turkey, north-eastern Syria, northern Iraq, north-western Iran and south-western Armenia.
