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 (Armenian: , [hɑj dɑt] or Hye 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 Hay Dat and shifted towards a modern Armenian nationalism modeled as a liberal nationalism. On the other hand, the Armenian diaspora have "diaspora nationalism," which maintain that the threat of assimilation rather than economic advantage.
The situation of the non-Muslim minorities within the Ottoman Empire changed substantially as a result of reforms introduced during the Tanzimat era. The early reforms were generally addressed at changing the organisation of, and systems within, the Ottoman Empire as a whole. However, as a result of diplomatic pressures exerted by the Great Powers that had supported the Ottoman Empire against Russia during the Crimean War, in 1856 reforms were made that sought to give non-Muslims citizens of the Ottoman Empire the same rights as Muslim citizens. The capitation tax on non-Muslims was abolished, non-Muslims were allowed to become soldiers, and schools for the non-Muslim communities were allowed to open.
