Fort Boise

Fort Boise refers to two different locations in southwestern Idaho. The first was a Hudson's Bay Company (HBC) trading post near the Snake River on the Oregon border (in present-day Canyon County), dating from the era when Idaho was included in the British fur company's Columbia District. After several rebuilds, the fort was ultimately abandoned in 1854, after it had become part of United States (US) territory following settlement in 1846 of the northern boundary dispute.

The second was established by the US government in 1863 as a military post located fifty miles (80 km) to the east up the Boise River. It developed as Boise, which became the capital city of Idaho.
