Sacagawea: Facts, Tribe & Death

Sacagawea is the most memorialized Native woman in the United States—the subject of dozens of statues and monuments—yet the documented record of her life is more compelling than any legend. A member of the Lemhi band of the Shoshone, born in 1788 or 1789 in the Salmon River region of what is now Idaho, she was captured as a girl, held at the Hidatsa-Mandan villages on the upper Missouri, and then carried west with the Lewis and Clark expedition—the Corps of Discovery—in 1804–1806. She translated across a chain of three languages, identified edible and medicinal plants, recalled Shoshone trails, and helped secure the horses that carried the expedition over the Rocky Mountains, all while caring for an infant son born two months before departure.

Who Was Sacagawea? A Lemhi Shoshone Childhood

Sacagawea grew up surrounded by the Rocky Mountains in the Salmon River country of present-day Idaho. The Shoshone were enemies of the gun-possessing Hidatsa, who kidnapped her during a buffalo hunt in 1800 and brought her to the Hidatsa-Mandan settlement near what is now Bismarck, North Dakota. The Mandan were an affiliated tribe.

The name most people know her by is Hidatsa: sacaga, meaning bird, and wea, meaning woman. Many Shoshone today argue that Sacajawea—which they translate as “boat-pusher”—is her true name, while North Dakota officially uses Sakakawea.

In 1803 or 1804, through a trade, a gambling payoff or a purchase, Sacagawea became the property of French-Canadian fur trader Toussaint Charbonneau, born no later than 1767 and more than two decades her senior. Having lived among Native people for years, he had adopted some of their traditions, including polygamy; Sacagawea became one of his two wives and was soon pregnant. Her captivity belonged to the wider economy of the fur trade companies of the northern plains, which bound Indigenous and European lives together across the Missouri River country.

The Louisiana Purchase and the Corps of Discovery

President Thomas Jefferson completed the Louisiana Purchase from France in 1803—828,000 square miles of almost completely unexplored territory. He hoped the wilderness held the rumored Northwest Passage, the legendary waterway linking the Atlantic and Pacific. He also charged his explorers with surveying the landscape, learning about the varied Native nations, collecting natural specimens and making maps. Jefferson turned to his secretary, Meriwether Lewis, who at 29 chose his friend and former military superior, 33-year-old William Clark, as co-captain.

After more than a year of planning and travel, the Corps reached the Hidatsa-Mandan settlement about 60 miles northwest of present-day Bismarck on November 2, 1804. Sacagawea was roughly six months pregnant. Lewis and Clark quickly recognized the value of the couple’s combined language skills. Most of the Corps spoke only English, but Francois Labiche spoke French; Charbonneau spoke French and Hidatsa; Sacagawea spoke Hidatsa and Shoshone—two very different languages. Through that chain, negotiations with the Shoshone became possible, and the Shoshone possessed the horses the expedition needed to cross the Bitterroot Mountains.

Sacagawea’s Skills and Her Role on the Expedition

Sacagawea delivered her son, Jean-Baptiste Charbonneau—known as Baptiste—on February 11, 1805. On April 7, she, the baby and Charbonneau headed west with the 31 other Corps members.

Within a month, a near-tragedy earned her particular respect. The boat she was aboard nearly capsized when a squall struck and Charbonneau, the navigator, panicked. Sacagawea had the presence of mind to gather crucial papers, books, navigational instruments, medicines and provisions that might otherwise have been lost—all while ensuring her baby’s safety. In appreciation, Lewis and Clark named a branch of the Missouri River for her several days later. Clark, in particular, developed a close bond with her, and she and Baptiste often accompanied him as he walked the shore checking for obstacles in the river. Her daily labor, from food gathering to camp work, reflects the central economic roles that women held in Plains tribal societies.

Sacagawea also put a naturalist’s knowledge to use. She could identify roots, plants and berries that were edible or medicinal, digging wild licorice and prairie turnips—tubers the explorers called “white apples”—with a sharp stick. Her memories of Shoshone trails led Clark to describe her as his “pilot,” and she helped guide the Corps through a mountain pass, today’s Bozeman Pass in Montana, toward the Yellowstone River. Although it could not be quantified, the presence of a woman and infant made the whole corps appear less fearsome and more amiable to Native nations they encountered, some of whom had never seen European faces—easing tensions that might otherwise have produced uncooperativeness at best, violence at worst.

Cameahwait, Lemhi Pass, and the Horse Trade

Five days after the first members of the Corps crossed the Continental Divide at Lemhi Pass, Sacagawea did the same and, as planned, translated the captains’ desire to purchase horses to the Shoshone they met. She was astonished and joyful to recognize the Shoshone leader, Chief Cameahwait, as her brother, and the siblings had an emotional reunion. The horses obtained through that encounter made the crossing of the Bitterroot Range possible, illustrating the historical impact of horses on Plains Indian culture and diplomacy.

After the Expedition: Wages, Family, and Hardship

After reaching the Pacific, Sacagawea returned with the rest of the Corps, her husband and son—having survived illness, flash floods, temperature extremes, food shortages and mosquito swarms—to the Hidatsa-Mandan settlement on August 14, 1806. For his service Charbonneau received 320 acres of land and $500.33. Sacagawea herself received no compensation.

Three years later, in fall 1809, the family traveled to St. Louis, where Charbonneau took up an offer from the kind-hearted Clark: land to farm if the parents would allow Clark to educate Baptiste. The farming did not succeed, and in April 1811 Sacagawea and Charbonneau left Baptiste in St. Louis with Clark—now his godfather—so they could join a fur-trading expedition.

How Did Sacagawea Die?

In August 1812, after giving birth to a daughter, Lisette, Sacagawea’s health declined. By December she was extremely ill with “putrid fever,” possibly typhoid fever. She died at 25 on December 22, 1812, at Fort Manuel, on a bluff 70 miles south of present-day Bismarck. She may have been buried on the Wind River Reservation, occupied by the Lemhi Shoshone, though some scholars dispute that account, and some Shoshone oral traditions hold that she lived far longer.

Within a year, Clark became legal guardian to both Lisette and Baptiste. Little is known of Lisette’s life. Baptiste traveled in Europe and held a variety of jobs in the American West before his death in 1866; Charbonneau died in 1843.

Memory, Memorials, and the “Indian Princess” Myth

Sacagawea’s fictionalized image as a “genuine Indian princess” was promulgated most widely in the early 20th century by a popular 1902 novel by Eva Emery Dye. A suffragist, Dye was not satisfied to present the facts then known; she wanted a compelling model of female bravery and intelligence, and did not mind rewriting history to create one. “Out of a few dry bones I found in the old tales of the trip, I created Sacajawea,” Dye wrote in her journal. Scholars today contend that romanticized versions of the Sacagawea legend do the real woman a disservice, because her documented accomplishments speak for themselves.

In addition to numerous memorials across the United States, she was honored with a dollar coin struck by the U.S. Mint from 2000 to 2008. The manganese brass coin shows Sacagawea carrying Jean-Baptiste, and she looks directly at the viewer—a break with coin-making tradition, in which subjects are shown in profile. Designer Glenna Goodacre used a modern-day Shoshone student as her model.

Historical Context & Key Cultural Takeaways

• Origins: Sacagawea was Lemhi Shoshone, born in 1788 or 1789 in the Salmon River region; her capture by the Hidatsa in 1800 placed her at the Hidatsa-Mandan villages, where she was later held by trader Toussaint Charbonneau.
• Role: She served as an interpreter in a three-language chain, a food gatherer and naturalist, a guide Clark called his “pilot,” and a diplomatic presence whose calm demeanor and infant son signaled peaceful intent.
• Contract and compensation: Charbonneau received 320 acres and $500.33 for his service; Sacagawea received nothing—an imbalance that reflects the legal and social status of women, and especially Native women, of the era.
• Death and dispute: The Fort Manuel record places her death at 25 on December 22, 1812; claims about a Wind River burial remain contested among scholars and tribal communities.
• Memory: The 1902 Dye novel, statues, and the U.S. Mint dollar coin shaped popular memory, while her true legacy rests on the expedition record itself.

Frequently Asked Questions About Sacagawea

What tribe was Sacagawea from?

She was a member of the Lemhi band of the Shoshone, born in the Salmon River region of present-day Idaho. Captured by the Hidatsa in 1800, she was taken to the Hidatsa-Mandan settlement near present-day Bismarck, North Dakota.

Why is her name spelled several ways?

The best-known spelling is Hidatsa, from sacaga (bird) and wea (woman). Many Shoshone argue that Sacajawea, meaning “boat-pusher,” is her true name, and North Dakota officially uses Sakakawea.

What did Sacagawea actually do on the Lewis and Clark expedition?

She interpreted through a chain of Hidatsa, Shoshone and French, gathered and identified edible and medicinal plants, recalled Shoshone trails, helped procure horses at Lemhi Pass, and calmed encounters between the Corps and Native nations. She gave birth to Baptiste two months before departing.

Did Sacagawea receive any payment?

No. Charbonneau received 320 acres and $500.33 for his service, but Sacagawea received no compensation for her work.

How did Sacagawea die, and where is she buried?

She died on December 22, 1812, at Fort Manuel, roughly 70 miles south of present-day Bismarck, after an illness described as “putrid fever,” possibly typhoid. Reports of a burial on the Wind River Reservation are disputed, and some oral traditions hold that she lived much longer.

Cultural Legacy and Modern Preservation

Sacagawea’s legacy is now carried mainly by the Shoshone, Hidatsa and Mandan communities who keep her story in tribal memory, and by museums and institutions such as the National Women’s Hall of Fame. Careful commemoration today emphasizes accuracy over romance: the enslaved girl who became an interpreter, mother and guide is a more meaningful figure than any invented princess.
