 Paul Henze, meanwhile, credits the events of the 1860s in Circassia with inspiring the Armenian Genocide at the hands of the Ottoman Empire, to whose lands the Circassians had been deported.Ellman, meanwhile, in a book review of Richmond's "Circassian Genocide", agrees that the term's use is justified under the UN definition as referring to actions intending to destroy "in whole or in part an ethnic group", with the part referring to those Circassians whom St Petersberg thought could not accept its rule.Walter Richmond also argues the term "genocide" is appropriate, considering the events of 1864 to have been "one of the first examples of modern social engineering".
