He authored the
General History of the Greek Revolution (Γενική Ιστορία της Ελληνικής Επαναστάσεως), published in 1863–64 in Athens. The first volume of his work contains a large chapter on the history of
Souli and the Souliotes, which is one of the few primary sources on the subject, written by a Souliote. Koutsonikas, based on oral tradition, claims that Souliotes resisted the Ottoman invasion since 15th century and they remained free and independent till early 19th century, and were the first who revolted in 1820. The name of his clan is mentioned in some of the Souliotic Songs, initially published by
Claude Fauriel in 1823 and republished later by others. ==References==
