Caucasian War
Historically, "auls" were a Circassian type of rural locality. Many of the present-day "auls" were founded during 1850 to 1925, when the Adyghe people were subject to mass deportations as a consequence of the Caucasian War of 1817–1864. These "auls" tend to be located in mountainous or otherwise difficult-to-access terrains, while most of those established after the Caucasian War are found on the plains beside the Caucasus Mountains.
