. At first, Indians traded beaver pelts for Euro-American goods because there was demand for beaver hats in the East and in Europe. During the 1830s, silk and woolen hats became more popular and demand for beaver pelts decreased. The trade shifted to bison robes. During the historical period, Fort Union served as a haven for many frontier people and contributed to economic growth on the American northwestern frontier. As headquarters for the American Fur Company, it played a primary role in the growth of the fur trade. Fur trade entrepreneurs, such as Astor and successors, exerted considerable influence on government policies that affected the Indian nations of the region. The presence of the fort near the northern border of the United States also symbolized national sovereignty in the region. The fort maintained a large inventory of firearms that were traded with Indian tribes for furs. In turn, Indians used the firearms in hunting for furs and buffalo robes. Northern Plains Indians preferred the English-made "North West Gun," a smooth-bore flintlock, because of its reputation for quality and reliability. Conflicts between Euro-American traders and Indians were less frequent around Fort Union than were conflicts among the Indian tribes themselves. However, during the summer of 1863, following the Dakota Wars of 1862, many tribes along the upper Missouri River became openly hostile to whites. At times Fort Union was nearly under siege, and the steamboats and their passengers were exposed to significant danger along the river. Chittenden, 1903, Vol. II, p. 324 In May 2025, an armed individual barricaded himself inside Fort Union Trading Post National Historic Site, prompting a law enforcement response. The individual confronted a park employee at the entrance while armed with a fire poker and escorted them off the property. Damage to park structures was discovered, including a broken lock and a missing donation box. The suspect was later observed inside the fort, armed with firearms, and claimed to have ample supplies to remain barricaded within the site. He also threatened to burn down the fort and destroy historical artifacts. Later in the day, a SWAT team and negotiators successfully secured the individual’s surrender. The incident marked a rare instance in recent history in which a historic fort was unlawfully occupied and temporarily taken control of by an armed individual.
