The obsession of the Islamic extremist forces in Chechnya with Russia's century-old rule is the historical root of the Chechen crisis, which is located in the mountainous and densely forested North Caucasus region of Russia. There are dozens of ethnic groups who believe in Islam, such as Chechnya, Ingushetia, awar, Ossetia, Lezkin, Kabardino, Darkin, Kumek and Adige. Since ancient times, these mountaineers are like goshawks flying over Caucasus Mountain, accustomed to freedom and freedom. Chechens, in particular, have been accustomed to "grabbing food for a living" in history, that is, relying on raids to get their own food from neighboring areas, rather than living under the control of others. For centuries, Russia's conquest and rule of Chechnya has deeply buried the revenge psychology of Russian pagans in the hearts of Islamic extremists in Chechnya. Since Islam spread in Chechnya and Ingushetia in the16th century, Islamic extremist forces in this region have been very active, accompanied by separatist and terrorist activities.

1722 In the process of expansion, Russia invaded Chechnya, built roads and castles there, and established Cossack villages and towns in an attempt to permanently occupy Chechnya. Chechens, unwilling to succumb to the czar's rule, United with other ethnic groups in the region and launched a long-term struggle with the Russian army. Subsequently, from 18 17- 1864, Russia conquered Chechnya after nearly half a century of "Caucasus War", which consumed a lot of manpower and material resources and paid a heavy price. Tolstoy, a great Russian writer, lamented: "Chechens are tough guys who are not afraid of death."
