[4] Laudaev has only one work titled The Chechen Tribe, published in the Collection of information about the Caucasian highlanders [ru] in 1872.
Based mainly on personal observations, as well as on folklore, linguistic and historical evidence, Laudaev mentioned daily information about the origins and settlement of the Chechen and Ingush tribes and the social system and culture of their people.
[5] One must critically approach Laudaev's work as it contains a lot of anti-national simplification; in addition, the author was under the influence of official Russian historiography.
[5] Chakh Akhriev's works that contained newly recorded legends about the emergence of Ingush societies and the founding of some auls, along with materials collected by Adolf Berge and Laudaev about the Chechens, served as the only primary sources in the absence of others that the first Soviet authors incorrectly used to judge about the history of the formation of the Chechens and Ingush.
The typical features of the legends were that: firstly, the Chechens and Ingush in the Middle Ages came to their modern lands from somewhere else, and secondly, that the ancestors of individual teips came from very different regions (e.g. Georgia, Syria, Persia).
