Manchuria is a term that refers to a region in Northeast Asia encompassing the entirety of present-day Northeast China, and historically parts of the modern-day Russian Far East, often referred to as Outer Manchuria. Its definition may refer to varying geographical extents as follows: the Chinese provinces of Heilongjiang, Jilin, and Liaoning but broadly also including the eastern Inner Mongolian prefectures of Hulunbuir, Hinggan, Tongliao, and Chifeng, collectively known as Northeast China; the aforementioned regions plus the homelands of ancient Jurchen and their descendant Manchus ceded to the Russian Empire by the Manchu-led Qing dynasty during the Amur Annexation of 1858–1860, which include present-day Primorsky Krai, the Jewish Autonomous Oblast, the southern part of Khabarovsk Krai, the eastern edge of Zabaykalsky Krai, and Amur Oblast, collectively known as the Outer Manchuria or Russian Manchuria.
The Treaty of Aigun was an 1858 treaty between the Russian Empire and Yishan, official of the Qing dynasty of China. It established much of the modern border between the Russian Far East and China by ceding much of Manchuria, now known as Northeast China. Negotiations began after China was threatened with war on a second front by Governor-General of the Far East Nikolay Muraviev when China was suppressing the Taiping Rebellion. It reversed the Treaty of Nerchinsk (1689) by transferring the land between the Stanovoy Range and the Amur River from the Qing dynasty to the Russian Empire. Russia received over 600,000 square kilometers (231,660 sq mi) of what became known as Outer Manchuria. While the Qing government initially refused to recognize the validity of the treaty, the Russian gains under the Treaty of Aigun was affirmed as part of the 1860 Sino-Russian Convention of Peking.
The Treaty of Nerchinsk of 1689 was the first treaty between the Tsardom of Russia and the Qing dynasty of China. The Russians gave up the area north of the Amur River as far as the Stanovoy Range and kept the area between the Argun River and Lake Baikal. This border along the Argun River and Stanovoy Range lasted until the Amur Annexation via the Treaty of Aigun in 1858 and the Convention of Peking in 1860. It opened markets for Russian goods in China, and gave Russians access to Chinese supplies and luxuries.
Aigun was a historic Chinese town in northern Manchuria, situated on the right bank of the Amur River, some 30 kilometres (19 mi) south (downstream) from the central urban area of Heihe.
Outer Manchuria, sometimes called Russian Manchuria, refers to a region in Northeast Asia that is now part of the Russian Far East but historically formed part of Manchuria. While Manchuria now more normatively refers to Northeast China, it originally included areas consisting of Priamurye between the left bank of Amur River and the Stanovoy Range to the north, and Primorskaya which covered the area in the right bank of both Ussuri River and the lower Amur River to the Pacific Coast. The region was ruled by a series of Chinese dynasties and the Mongol Empire, but control of the area was ceded to the Russian Empire by the Qing China during the Amur Annexation in the 1858 Treaty of Aigun and 1860 Treaty of Peking, with the terms "Outer Manchuria" and "Russian Manchuria" arising after the Russian annexation. The same general area became known as Green Ukraine after a large number of settlers from Ukraine came to the region.
Heihe is a prefecture-level city of northern Heilongjiang province, China, located on the Russian border, on the south bank of the Amur (Heilong) River, across the river from Blagoveshchensk. At the 2020 census, 1,286,401 people lived in the prefecture-level city of whom 223,832 lived in the built-up area made of Aihui District.
The Treaty of Kyakhta, along with the Treaty of Nerchinsk (1689), regulated the relations between Imperial Russia and the Qing Empire of China until the mid-19th century. It was signed by Tulišen and Count Sava Lukich Raguzinskii-Vladislavich at the border city of Kyakhta on 23 August 1727.
Nerchinsk is a town and the administrative center of Nerchinsky District in Zabaykalsky Krai, Russia, located on the left bank of the Nercha River, 7 kilometers (4.3 mi) above its confluence with the Shilka River, 644 kilometers (400 mi) east of Lake Baikal, about 225 kilometers (140 mi) west of the Chinese border, and 305 kilometers (190 mi) east of Chita, the administrative center of the krai. Population: 14,959 (2010 Census); 15,748 (2002 Census); 16,961 (1989 Census); 6,713 (1897).
Prior to the 17th century, China and Russia were on opposite ends of Siberia, which was populated by independent nomads. By about 1640 Russian settlers had traversed most of Siberia and founded settlements in the Amur River basin. From 1652 to 1689, China's armies drove the Russian settlers out, but after 1689, China and Russia made peace and established trade agreements.
Albazino is a village (selo) in Skovorodinsky District of Amur Oblast, Russia, noted as the site of Albazin (Албазин), the first Russian settlement on the Amur River.
The Sino-Russian border conflicts (1652–1689) were a series of intermittent skirmishes between the Qing dynasty of China, with assistance from the Joseon dynasty of Korea, and the Tsardom of Russia by the Cossacks in which the latter tried and failed to gain the land north of the Amur River with disputes over the Amur region. The hostilities culminated in the Qing siege of the Cossack fort of Albazin in 1686 and resulted in the Treaty of Nerchinsk in 1689 which gave the land to China.
The Albazinians are one of the few groups of Chinese of Russian descent. There are approximately 250 Albazinians in China who are descendants of about fifty Russian Cossacks from Albazin on the Amur River that were resettled by the Kangxi Emperor in the northeastern periphery of Beijing in 1685. Albazin was a Russian fort on the Amur River, founded by Yerofey Khabarov in 1651. It was stormed by Qing troops in 1685. The majority of its inhabitants agreed to evacuate their families and property to Nerchinsk, whereas several young Cossacks resolved to join the Manchu army and to relocate to Beijing. See Sino-Russian border conflicts.
Between 1858 and 1860, the Russian Empire annexed territories adjoining the Amur River belonging to the Chinese Qing dynasty through the imposition of unequal treaties. The 1858 Treaty of Aigun, signed by the general Nikolay Muravyov representing the Russian Empire and the official Yishan representing Qing China, ceded Priamurye—a territory stretching from the Amur River north to the Stanovoy Mountains, but the Qing government initially refused to recognize the treaty's validity. Two years later, the Second Opium War concluded with the Convention of Peking, which affirmed the previous treaty as well as an additional cession including the entire Pacific coast to the Korean border, as well as the island of Sakhalin to Russia. These two territories roughly correspond to modern-day Amur Oblast and Primorsky Krai, respectively. Collectively, they are often referred to as Outer Manchuria, part of the greater region of Manchuria.
Jaxa was a 17th-century microstate in North Asia with its capital in Albazino existing between 1665 and 1674. It was located on the border of the Tsardom of Russia and Qing China, by the Amur river. Its population was made up of Polish and Ukrainian refugees from the Tsardom of Russia, and the indigenous Evenks and Daurs. It was established from the territory of the Tsardom of Russia in 1665 by Nikifor Chernigovsky and his men, who fled Russia, and existed until 1674 when it was incorporated back to that country.
The Kyakhta Trade refers to the trade between Russia and China through the town of Kyakhta on the Mongolian border south of Lake Baikal from 1727. The trade was mostly Siberian furs for Chinese cotton, silk, tobacco and tea.
Manchuria under Qing rule was the rule of the Qing dynasty of China over the greater region of Manchuria, including today's Northeast China and Outer Manchuria, although Outer Manchuria was lost to the Russian Empire after the Amur Annexation. The Qing dynasty itself was established by the Manchus, a Tungusic people from Manchuria, who later replaced the Ming dynasty as the ruling dynasty of China. Thus, the region is often seen to have had a special status during the Qing and was not governed as regular provinces until the late Qing dynasty, although the name "Manchuria" itself is an exonym of Japanese origin and was not used by the Qing dynasty in Chinese or Manchu.
Oros Niru was a military unit of the Qing dynasty of China. It consisted of Russian Cossacks that were captured during the border conflicts between the Russian Empire and Qing China. Formally, this niru was known as the 17th niru of the 4th jalan of the Manju Gusa ejen of Bordered Yellow Banner (鑲黃旗滿洲都統第四參領第十七佐領).
