The name of the country is descended from the wooden stronghold of Jaxa built by Nikifor Chernigovsky in place of Albazino that was destroyed by Chinese troops. According to Chinese sources, this place was called 雅克萨 before the rise of Albazino. The name of the state was given from the founder's family name, Jaksa.
History
The state was created by Nikifor Chernigovsky, a Polish noble deported from Volhynia. In 1665 Chernigovsky and Siberian Cossacks killed a voivode of Ust-Ilimsk. Then, they rebuilt an abandoned stronghold of Albazino to hide in it. The stronghold became the capital of their new state. In 1685 Jaxa became a part of the Qing dynasty.
Albazin
In late 1650 Albazin was built as winter quarters by Yerofei Khabarov on the northernmost part of the Amur River, 125 miles downstream from the junction of the Argun and Shilka. Thereafter it was little used as the Russians concentrated on the richer grain-growing lands downriver. In 1652 the Manchus drove the Russians out of the Amur country and the land was left to outlaws and adventurers.
Foundation of Jaxa
In 1655 Nikifor Chernigovsky, a Pole who had been exiled to Siberia after an unsuccessful attempt to run away from the Russian's custody, murdered the voivode of Ilimsk in retaliation for the rape of his daughter, and fled to the Amur where he reoccupied the ruins of Albazin and gathered a band of supporters. Chernigovsky soon gained the support of the local population, Tungusic people, for whom treatment with respect was a great change in comparison to several assaults they underwent over Russians sovereignty. He made a great stronghold on the ruins of Albazin giving it the name of Jaxa. In the coming years, Siberian governors made several failed attempts to regain the control over Albazin; however, Chernigovsky was able to keep his position playing Russians against Chinese people and vice versa. From 1669, the Russian tsar received a tribute from the Jaxa country, which impacted on the tsar's decision to formally acknowledge Chernigovsky as the lord of Jaxa in 1674. In communication with Chernigovsky, the Chinese government used Polish as the main language. In 1675 he raided Chinese lands with the help of the local population. It's the last recorded reference to Chernigovsky in history.
The Russian-Chinese conflict over Albazin
The Manchus did little about Albazin because their forces were tied up in southern China and because they were concerned about possible Russian backing for their enemies in Mongolia. With the southern problem nearly solved, in the spring of 1682 the Kangxi Emperor made a tour through Manchuria and began preparations to deal with the Amur problem. His plan was to build up such a large force that the Russians would withdraw without fighting, for, as he said "The use of force is not a good thing. We use it only under compulsion." Troops were moved up to Aigun and crops were planted to feed them. An attack was delayed due to disagreements among the planners and the difficulty of moving supplies northward. From 1681 there were Manchu threats against Albazin, talks were held on the Nun River and minor Russian forts were destroyed along the Zeya. By the end of 1683, all Russian bases except Albazin had been eliminated. Moscow responded by making Ivan Vlasov voyevoda of Nerchinsk and appointing Akeksey Tolbuzin to a new voivodeship at Albazin. An attempt to move men and supplies east failed due to shortages and inefficiency. The siege began on June 23, 1685. On the 26th there was an indecisive day-long battle. The Manchus thereupon piled dry wood along the fort's wooden walls and when they began to light it, Tolbuzin surrendered. The 600 or so defenders were allowed to withdraw to Nerchinsk. About 45 opted to go with the Manchus where they joined the Russian colony in Peking. The Manchus burned the fort and withdrew, but did not destroy the crops. When news of the defeat reached Moscow in November it was decided to abandon the Amur and send an ambassador to Peking. In 1686, one day after leaving Albazin, the retreating Russians met a group of reinforcements who brought word that an even larger group under Baiton had reached Nerchinsk. Since the fort was lost they continued their withdrawal. Sometime after July 10, 1685, scouts reported that the Manchus were gone and the crops still standing. Vlasov sent 669 well-armed men under Tolbuzin to gather the harvest. The crops were gathered, Albazin was refortified with earthen walls and efforts were made to bring the natives back into subjection. The Manchus arrived on July 18, 1686, and began a tight siege and a steady cannonade. On the fifth day of the siege, Tolbuzin was killed by a cannonball and replaced by Afanasii Baiton. The Russians had enough food to last until Easter, but were short of water. The siege continued until early winter. In late October messengers arrived in Peking announcing Moscow's desire to negotiate. An order was issued to relax the siege. At this time less than 66 men, out of an original 826, were left alive. On December 25 Baiton sent one of his men to request provisions. A few more than twenty men remained in the fort, all ill and undernourished. When, in August 1687, Kangxi heard that the Russian ambassador had reached Mongolia, he ordered the Manchu troops withdrawn. By the Treaty of Nerchinsk in 1689, Albazin was abandoned and destroyed.
