Leo never received a higher education and his knowledge and erudition was almost entirely self-taught. He first began to write in the late 1870s. Over the years, he wrote for various Armenian newspapers and journals, such as '
, ', , , and
. He was influenced by the liberal nationalist writers
Raffi and
Grigor Artsruni (the founder of ''''). From about 1880 to 1900, Leo mostly wrote works of fiction, reviews, and articles on contemporary issues, whereas from 1900 onward, he focused on writing history. In 1901–1902, he published a two-volume work titled (Armenian printing), which studies the cultural, intellectual and political life of Armenians between the sixteenth and eighteenth centuries. Leo's most noteworthy work is his three-volume
History of Armenia (, vol. 1 originally published in Tiflis, 1917; vols. 2 and 3, Yerevan, 1946–1947; republished in 1966–73). His work traces Armenian history from its beginnings until the end of the nineteenth century, with the exception of the period stretching from the eleventh to the fifteenth centuries (the third volume begins with the sixteenth century, whereas the second volume ends in the eleventh). It devotes particular importance to the political, cultural and social issues that surrounded Armenian life and the role that Armenia's neighbors played in the country's history. Leo's
History is valued for its extensive use of primary and secondary sources and for its engaging and understandable style. After Soviet Russian writer
Andrei Bitov visited Yerevan in 1960, he remarked that "he did not enter any house which did not have the familiar three volumes of Leo's
History of Armenia." Besides his historical and social-political writings, Leo also wrote some literary criticism, translations of European authors, and a number of fictional works in the style of
realism. These works included short stories, novels, and plays, almost all dating to the earlier part of his career. For Leo, literature was more important as a means of moral and intellectual education than as a form of artistic expression. The usual theme of his short works is the backwardness and misery of Armenian rural life. His stories set in cities depict the injustices of the capitalist system. A few of his short stories and his novel (The melik's daughter) are set in his native Karabakh. in
