 Until 1828, Khoy had a large number of Armenians, however, the Treaty of Turkmenchay following the outcome of the 1826–1828 war and the victory over the neighbouring Ottoman Empire as concluded in the Treaty of Adrianople, encouraged the mass resettlement of Armenians from both Turkey and Iran in Russia.In the mid-1800s some of them immigrated to eastern Armenia, which by then had just became part of the Russian Empire.However, a small Armenian population remains living in Khoy city and county.
