Chechens
Chechens (; '; Old Chechen: Нахчой "Naxçoy") are a Northeast Caucasian ethnic group of the Nakh peoples originating in the North Caucasus region of Eastern Europe. They refer to themselves as Vainakhs (which means "our people" in Chechen) or Nokhchiy (pronounced ; singular Nokhchi, Nakhchuo or Nakhtche). Chechen and Ingush peoples are collectively known as the Vainakh. The majority of Chechens today live in the Chechen Republic, a subdivision of the Russian Federation.
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.
