Chechens
In 1989, 73.4% spoke Russian, though this figure has declined due to the wars for a large number of reasons (including the lack of proper education, the refusal to learn the language, and the mass dispersal of the Chechen diaspora due to the war). Chechens in the diaspora often speak the language of the country they live in (English, German, Arabic, Polish, Georgian, etc.).
Chechnya
Islam is the predominant religion in Chechnya, practiced by 95% of those polled in Grozny in 2010. Chechens are overwhelmingly adherents to the Shafi'i Madhhab of Sunni Islam, the republic having converted to Islam between the 16th and the 19th centuries. Due to historical importance, many Chechens are Sufis, of either the Qadiri or Naqshbandi orders. Most of the population follows either the Shafi'i or the Hanafi, schools of jurisprudence, fiqh. The Shafi'i school of jurisprudence has a long tradition among the Chechens, and thus it remains the most practiced.
