Nagorno-Karabakh
Modern era

Karabakh (including modern-day Nagorno-Karabakh), became a protectorate of the Russian Empire by the Kurekchay Treaty, signed between Ibrahim Khalil Khan of Karabakh and general Pavel Tsitsianov on behalf of Tsar Alexander I in 1805, according to which the Russian monarch recognized Ibrahim Khalil Khan and his descendants as the sole hereditary rulers of the region. However, its new status was only confirmed following the outcome of the Russo-Persian War (1804-1813), when through the loss in the war, Persia formally ceded Karabakh to the Russian Empire per the Treaty of Gulistan (1813), before the rest of Transcaucasia was incorporated into the Empire in 1828 by the Treaty of Turkmenchay, which came as an outcome of the Russo-Persian War (1826-1828).

In 1822, 9 years after it passed from Iranian to Russian control, the Karabakh Khanate was dissolved and the area became part of the Elizavetpol Governorate within the Russian Empire. In 1823 the five districts corresponding roughly to modern-day Nagorno-Karabakh were 90.8% Armenian-populated.
