Armenian nationalism in the modern period has its roots in the romantic nationalism of Mikayel Chamchian (1738–1823) and generally defined as the creation of a free, independent and united Armenia formulated as the Armenian Cause (Հայ Դատ Hay Dat). Armenian national awakening developed in the 1880s in the context of the general rise of nationalism under the Ottoman Empire. The Russian Armenia followed with significant causes. The Armenian Apostolic Church has been a great defender of Armenian nationalism, with leaders like Khrimian Hayrik who devoted his life to the peasantry. The establishment of modern Armenia (1991) and Armenian social fabric becoming more complex gradually decrease the political influence of Hye Dat and shifted towards a modern Armenian nationalism modeled as a liberal nationalism.
