During the second Russo-Persian War of the 19th century, the Russo-Persian War of 1826–28, Yerevan was captured by Russian troops under general Ivan Paskevich on 1 October 1827. It was formally ceded by the Iranians in 1828, following the Treaty of Turkmenchay. After 3 centuries of Iranian occupation, Yereven along with the rest of Eastern Armenia designated as the "Armenian Oblast", became part of the Russian Empire, a period that would last until the collapse of the Empire in 1917. The Russians sponsored the resettlement process of the Armenian population from Persia and Turkey. Due to the resettlement, the percentage of the Armenian population of Yerevan increased from 28% to 53.8%. The resettlement was intended to create Russian power bridgehead in the Middle East. In 1829, Armenian repatriates from Persia were resettled in the city and a new quarter was built.
