Sacagawea's probable death recorded at Fort Manuel Lisa, marking an end to her remarkable journey.
On December 20, 1812, Fort Manuel Lisa records indicate the death of a woman believed to be Sacagawea. She reportedly died of putrid fever or typhus at the trading post in present-day North Dakota. Her passing marked the end of a short yet impactful life that saw remarkable achievements, including her vital role in one of the most famous exploratory missions in American history. Although some oral histories suggest she lived until 1884 on the Wind River Reservation, this 1812 date is commonly accepted. Her legendary status only grew following her death, as she became a celebrated historical figure and a symbol of perseverance, strength, and cultural bridge-building in early American expansion.
