Abrek
Abrek is a North Caucasian term. Origin from the Bible meaning in Hebrew "to kneel" or "prostrate in front of the God". Prior to Russian invasion into the Caucasus, and following Islamization of the North Caucasians in XVI-XIX century, majority of the North Caucasians were Christians. That is why from Chechen or Ingush the word abrek has the meaning as "avenger", from Cherkess or Karachai the word has the meaning as "brave man". In the Caucasus only in Ossetian and Russian the word has a derogatory meaning as "bandit", but they are of Indo-European language family. Once it was used for a person who vowed to avoid any pleasures and to be fearless in fight for the sake of the God. An abrek renounced himself from any contact with friend and relatives. Abrek lifestyle also included a lonely life in the unexplored wilderness and prayers. Later majority of abreks were devoted Muslims.
