Fort Assinniboine

Fort Assinniboine is a historic military post in Montana with over 100 buildings spread across its grounds, representing one of the largest installations from the state's territorial period. The complex now serves as an agricultural research center operated by Montana State University.

The Army built the post in 1879 following the Great Sioux War to maintain order and defend settlers across northern Montana. It became a key strategic location during a period of significant territorial expansion and settlement.

The 10th Cavalry Buffalo Soldiers, African-American troops, established their headquarters at the fort from 1892 onward and shaped military operations across the region. Their presence left a lasting mark on the post and the surrounding community.

The grounds are accessible today as an agricultural research center, with many of the historic buildings preserved and available to visit. Since it remains an active research facility, certain areas may have limited access depending on ongoing projects and activities.

The future General John Pershing commanded troops at the post before rising to lead the American Expeditionary Force during World War I. His early service there helped shape the leadership skills that would define his later career.
