Ukase of 1821: Russia claims sovereignty over northwestern North America

Background. Russian colonial possessions in the Americas, known as Russian America, existed from 1799 to 1867. The Ukase of 1799 established the southern border along the 55th parallel north. In 1821, the Russian-American Company's charter was renewed, stipulating that chief managers be naval officers. Emperor Alexander I continued the company's monopoly, requiring financial support for missionary efforts. These developments formed the institutional context surrounding the 1821 ukase.

Proclamation. The Ukase of 1821 declared territorial sovereignty over northwestern North America, roughly present-day Alaska and most of the Pacific Northwest. It was declared on September 4, 1821 (Old Style). The first section stated that commerce, whaling, fishing, and other industry on all islands, ports, and gulfs, including the whole northwest coast to 45°50′ north latitude, were included in the edict to grant exclusivity to Russian subjects.

Diplomatic Response. American and British diplomats strenuously objected to the Ukase of 1821. They noted that American, British, and French fur-trading vessels had frequented Norfolk Sound before Russia extended its claim eastward. The British pointed out that Captains Cook and Vancouver pre-dated any Russian assertion of sovereignty. The ukase's items figured prominently in the Alaska boundary dispute of 1821–1903. Washington responded in the Monroe Doctrine, promulgated in 1823.

Enforcement. The only attempt to enforce the ukase occurred in 1822, when the Russian sloop Apollon seized the American ship Pearl on its way from Boston to Novoarkhangelsk (now Sitka, Alaska). This action highlighted the practical difficulties of enforcing the broad territorial claims made in the 1821 proclamation, particularly given the prior presence of foreign vessels in the region.
