Brutal political, social, national and religious oppressions led to a massive liberation movement of the Armenian people in that period. In 1722-1730 a strong national-liberation movement broke out in Syunik led by David Bek. At that time the Russian Empire began to expand his country's southern borders and already by “Adrianopole Treaty” (1829) the accession of the Transcaucasia was mostly completed. In 1828 “Armenian Marz” (Region) was temporarily formed on the territories of the former Yerevan and Nakhichevan Khanates, which later became the basis of the rebuilt Armenian statehood. Since the beginning of the 19th century Armenia was divided between the Ottoman and Russian empires. The western and eastern parts of historical Armenia, populated with Armenians, are conditionally called Western Armenia and Eastern Armenia.
Not having independent and its own state, in the 20th century, Armenia stood on the edge of destruction. Taking advantage of the situation created as a result of the First World War, in February 1915 the War Minister of the “Young Turks” government Enver Pasha ordered to exterminate the Armenian soldiers serving in the Turkish army. On April 24 and subsequent days in Kostandnupolis (Istanbul) some 800 representatives of the Armenian intellectuals such as writers, doctors, scholars, journalists and clerics, including Armenian members of the Turkish Parliament, were arrested and deported far in Anatolia. After Armenian intellectuals and soldiers were killed, the Turks began their 2nd program of monstrous project. They began to kill peaceful civilians, women, elder population, children. The implementation result of this monstrous program, 1.5 million people were killed during Armenian Genocide. Western Armenia was deprived of its native population.
