In 1793 Alexander Baranov of the Shelikhov-Golikov company (precursor of the Russian-American Company) established a fur trade post on Resurrection Bay where Seward is today, and had a three-masted vessel, the Phoenix, built at the post by James Shields, an English shipwright in Russian service.
The 1939 Slattery Report on Alaskan development identified the region as one of the areas where new settlements would be established through Jewish immigration. This plan was never implemented.
Seward was an important port for the military buildup in Alaska during World War 2. Fort Raymond was established in Seward along the Resurrection River to protect the community. An Army airfield built in Seward during the war later became Walseth Air Force Base. Both of the military facilities were closed shortly after the end of the war.
A large portion of Seward was damaged by shaking and a local tsunami during the 1964 Alaska earthquake.
