Languages of Turkey
Turkish is the sole official language throughout Turkey. Reliable figures for the linguistic breakdown of the populace are not available for reasons similar to those cited above. According to CIA the Turkish language is spoken by 70–75% of people and the Kurdish language by approximately 18% of people.[120] The public broadcaster TRT broadcasts programmes in the local languages and dialects of Arabic, Bosnian, Circassian and Kurdish a few hours a week. A public television channel, TRT 6, which airs programs of Kurdish-language most of the time, was opened in early 2009

The Bahá'í Faith in Turkey has roots in Bahá'u'lláh's, the founder of the Bahá'í Faith, being exiled to Constantinople, current-day Istanbul, by the Ottoman authorities. Bahá'ís cannot register with the government officially but there are probably 10[137] to 20[138] thousand Bahá'ís, and around a hundred Bahá'í Local Spiritual Assemblies in Turkey
