Explorer Vasili Poyarkov led one of the first Russian expeditions from Yakutsk toward the Amur, crossing the Stanovoy Range and moving down the Zeya to the Amur. His journey helped Russian officials and Cossacks identify routes to the lower Amur and its farming communities. This set the stage for later armed expeditions aimed at extracting tribute and controlling river routes.
Yerofey Khabarov reached the upper Amur area (often called Dauria in Russian sources) and then returned to Yakutsk with a report. He advocated sending a larger force and warned that conflict with Qing power could follow. His reconnaissance linked the goal of expansion with a concrete military plan for the Amur frontier.
Khabarov’s detachment built winter quarters at Albazin and took over the local Daur fort site, creating a Russian foothold on the Amur. Albazin became a strategic base for collecting tribute (yasak) and for raids and resupply along the river. Its creation also sharpened tensions with local communities and with the Qing, which treated the area as within its frontier sphere.
A major clash occurred when Qing-allied forces attacked the Russian fort at Achansk (near today’s Khabarovsk) and were beaten back. The fighting showed that the Qing would intervene militarily when Amur communities appealed for protection or when frontier control was challenged. After this, both sides treated the Amur as a contested borderland rather than a remote frontier.
After internal disputes, Khabarov was arrested and taken away for investigation, leaving Amur operations to other leaders. This leadership disruption did not end Russian pressure on the region, but it weakened coordination and increased the role of smaller Cossack bands. The instability helped turn frontier raiding and fort-building into a cycle of retaliation.
Nerchinsk was founded as a fort in Transbaikalia, strengthening Russia’s logistical base behind the Amur. It became a staging point for frontier defense, administration, and later diplomacy. The fort’s existence mattered because it anchored Russia’s claim to the region even when the Amur line became hard to hold militarily.
On the Songhua River, Qing and Joseon (Korean) forces fought Cossacks under Onufriy Stepanov in a battle known as the Battle of Hutong. The result was a Qing-Joseon victory and a Russian retreat, showing that the Qing could organize effective river operations with allied troops. This also signaled a shift from local skirmishes to more structured border warfare.
A larger river battle on the Songhua River again pitted Stepanov’s Cossacks against Qing forces with Joseon participation. The Qing-Joseon victory destroyed or captured much of the Russian flotilla and killed many of the attackers. The defeat reduced Russia’s ability to project power downriver and helped the Qing regain initiative in the region.
A fugitive leader, Nikifor Chernigovsky, reoccupied the ruins of Albazin and rebuilt the stronghold, sometimes described as the center of a small frontier polity called Jaxa. This revived a permanent Russian-aligned presence on the Amur after earlier setbacks. The rebuilt fort became a key target because it symbolized renewed encroachment into an area the Qing sought to secure.
Qing forces under commanders including Langtan besieged Albazin and compelled its surrender; the fort was then burned. Some defenders withdrew to Nerchinsk, and some reportedly entered Qing service and resettled. The siege demonstrated the Qing’s ability to bring artillery and river transport to bear on the frontier, making Albazin’s wooden defenses inadequate.
Qing forces returned and opened the second siege of Albazin, aiming to eliminate the rebuilt outpost. Fighting and blockade conditions created severe losses inside the fort, with disease and starvation becoming decisive factors. The prolonged siege increased pressure on both governments to shift from raids and sieges to formal negotiations.
After the Qing withdrawal, Russian forces returned to Albazin to harvest crops and reconstruct the fortress with stronger earthworks. The rebuilt design was better suited to withstand artillery than the earlier wooden fortifications. This decision restarted the conflict cycle by reasserting a military foothold in the Amur basin.
Russia and the Qing dynasty signed the Treaty of Nerchinsk, the first formal treaty between the two states. Russia agreed to remove its outposts from the Amur basin, while retaining Transbaikalia and securing regulated relations and trade contacts. The treaty marked a clear endpoint for the 1650–1689 Amur campaigns by replacing frontier warfare with a negotiated border framework.
