Wahhabism, which spread to Muslim countries such as Morocco and Indonesia in the second half of the 18th century, began to spread to the North Caucasus at the end of the 20th century. The first Wahhabi society in the North Caucasus was established in 1970 during the Soviet era. At that time, the spread of Wahhabism in the Caucasus was in line with the interests of Western countries. Because they tried to show the radical position of the Muslims living in the USSR against the empire. After the collapse of the USSR in the early 1990s, facilitating the arrival of missionaries to the region provided a fertile ground for the spread of Wahhabism. On the other hand, the prohibition of the USSR on religion for a long time caused the North Caucasian Muslims to fall behind on the true nature of religion and traditional Islam. Therefore, missionaries took extensive advantage of this situation. Fethi al-Shasani, a Jordanian torch bearer and a US citizen, played an exceptional role in the development of radical Wahhabi extremism in Chechnya. During the Chechen-Russian war, Fethi al-Şaşani formed a Wahhabis battalion known as Jamaat and declared the war a "holy war". However, Fethi al-Şaşani is thought to have harmed the Caucasus more than Russia on the pretext of war with the Russian Federation. Because he deceived hundreds of young people by gathering them around him and threatened the peace and security in the region. In this case, Russia, the strongest state in the region, launched destructive military operations in the North Caucasus geography, including Chechnya. As a result of all these, the North Caucasians who believe in Islam have suffered serious material and moral blows. After the collapse of the USSR, Wahhabi extremism has been one of the factors that disturbed socio-political stability in the North Caucasus and security in the region in general. Wahhabis first opposed traditional Islam in the Caucasus and began to declare the leaders of the clergy in the region as enemies of Islam. At the same time, they intensified their armed struggle to eliminate Sufi sects such as Naqshbandi, Qadiri and Shazili, which had a great influence on the spread of traditional Islam in the Caucasus. As a result, when the conflict between Sufi sects and Wahhabis increased, Sheikh Said, a well-known clergyman in the Caucasus and the Naqshbandi Sheikh Said, tried to drive the Wahhabis of the Caucasian Muslims out of the region. The paper analyzes the birth of Wahhabiz, its extremist ideas, and its development in the North Caucasus and Chechnya.
