Sacagawea is remembered in US history as the Shoshone Native American woman who acted as interpreter to the Lewis and Clark Expedition, the early 19th-century mission to chart territory in the American West after the Louisiana Purchase. But what impact did her contributions have on the success of this eventful journey? How did her presence influence interactions with the various Native American tribes the expedition party encountered? And how has her legacy been interpreted and commemorated in the years since? Speaking to Rebecca Franks, Stephenie Ambrose Tubbs delves into the life of Sacagawea – from what we know about her early years to what her story can reveal about broader cultural attitudes toward Indigenous people in American history.
