Eastern Question
After completing his Asia Minor researches, Chikhachyov ended his great travels and expeditions, having reached old age, but did not stop scientific work. In early 1878, at the age of 71, he visited Algeria and Tunis, and in 1880 he published a description of his travel under the title "Espagne, Algérie et Tunisie". Besides his geographical and natural-historical works, Chikhachyov published a number of political works on the Eastern Question.
