Captain James Cook’s expedition anchored at Nootka Sound (on Vancouver Island), initiating sustained British maritime activity on the Northwest Coast that soon expanded northward into Indigenous trade networks affecting Tlingit and Tsimshian territories.
Tsar Paul I issued the 1799 ukase establishing the Russian-American Company, formalizing a monopoly and administrative structure that intensified Russian colonization and conflict in Tlingit homelands in Southeast Alaska.
Kiks.ádi Tlingit forces attacked and destroyed the Russian outpost at Old Sitka (near present-day Sitka), a pivotal escalation in the Russo–Tlingit conflict that prompted a major Russian retaliation.
Russian-American Company forces under Alexandr Baranov, supported by naval firepower and allied Aleut laborers/hunters, fought the Kiks.ádi Tlingit near Sitka; the battle ended with Tlingit withdrawal and Russian consolidation at New Archangel (Sitka).
After years away following the 1804 conflict, Kiks.ádi Tlingit returned to the Sitka area and rebuilt their community near the Russian fortified settlement, shaping a long period of tense proximity and trade under colonial rule.
Construction of St. Michael’s Cathedral (funded by the Russian-American Company and associated with Bishop Innocent/Veniaminov) concluded in 1848, marking a major institutional foothold for Russian Orthodox missionization in a key Tlingit region.
Church Missionary Society lay missionary William Duncan reached Fort Simpson (Lax Kw’alaams/Port Simpson) in 1857 and began organized Anglican mission work among Tsimshian communities, including language learning and translation efforts.
William Duncan and Tsimshian followers founded Metlakatla (near present-day Prince Rupert) in 1862 as a Christian settlement intended to separate converts from the Hudson’s Bay Company fort environment, becoming a central site of Tsimshian missionization and social change.
The United States acquired Alaska from Russia in 1867, ending Russian-American Company governance; the change in sovereignty created new legal and political conditions for Tlingit communities, while leaving Indigenous land title unresolved.
Presbyterian missionary Sheldon Jackson arrived in Sitka in 1877 and soon organized mission and schooling initiatives aimed at Alaska Native youth (including Tlingit), shaping U.S.-era Protestant missionization and assimilationist education in Southeast Alaska.
At the request of Chilkat Tlingit leaders, Sheldon Jackson organized a Presbyterian mission and school at Deishú (later Haines), embedding church influence and schooling along major Tlingit trade corridors linking coast and interior.
Congress’s Organic Act of 1884 created a civil government for the District of Alaska and stated that “Indians or other persons” should not be disturbed in lands they used, while explicitly reserving (postponing) the terms for acquiring legal title—an important context for later Tlingit land and treaty-related disputes.
A large group of Tsimshian, led by William Duncan, migrated from British Columbia to Annette Island in Alaska in 1887–1891, establishing New Metlakatla and seeking a different governance and church arrangement than in Canada.
An Act of Congress set aside Annette Island as a reserve for the Metlakatla (Tsimshian) community, creating what became the only federal Indian reservation in Alaska and a key legal landmark in Indigenous–U.S. relations in Southeast Alaska.
The 1903 arbitration settled the long-running Alaska boundary dispute between the United States and Britain/Canada, fixing key Southeast Alaska boundary interpretations that affected regional access, travel, and governance in Indigenous homelands including Tlingit areas.
