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.

In the early 20th Century, many Kurds began to consider the creation of a homeland. Such hopes were dashed three years later, however, 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 their respective countries.
