The Treaty of Aigun redefined the territorial boundaries between Qing China and the Russian Empire, significantly altering the geopolitical landscape of Manchuria.
Signed in 1858, the Treaty of Aigun marked a pivotal moment in Sino-Russian relations, as it resulted in the cession of vast territories in Manchuria to the Russian Empire. This treaty was a consequence of the Qing Dynasty's weakened state following internal strife and external pressures, notably the Second Opium War. The agreement shifted the Amur River to become the new boundary, granting Russia control over the left bank and access to the Pacific Ocean. This territorial gain significantly expanded Russian influence in Asia, setting the stage for further expansionist policies. The treaty's significance lies not only in its immediate territorial implications but also in its role in the broader context of 19th-century imperialism, highlighting the vulnerabilities of the Qing Dynasty and the aggressive expansionism of the Russian Empire.
