Sacagawea was born in 1788 near the Continental Divide at the present-day Idaho-Montano border. Shoshone Indian woman who, as interpreter, traveled thousands of wilderness miles with the Lewis and Clark Expedition in 1804 – 1806, from the Mandan-Hidatsa villages in the Dakotas to the Pacific Northwest.

A Lemhi Shoshone woman, she was about 12 years old when a Hidatsa raiding party captured her near the Missouri River’s headwaters about 1800. Enslaved and taken to their Knife River earth-lodge villages near present-day Bismarck, North Dakota, she was purchased by French Canadian fur trader Toussaint Charbonneau and became one of his plural wives about 1804. They resided in one of the Hidatsa villages, Metaharta.

When explorers Meriwether Lewis and William Clark arrived at the Mandan-Hidatsa villages and built Fort Mandan to spend the winter of 1804–05, they hired Charbonneau as an interpreter to accompany them to the Pacific Ocean. Because he did not speak Sacagawea’s language and because the expedition party needed to communicate with the Shoshones to acquire horses to cross the mountains, the explorers agreed that the pregnant Sacagawea should also accompany them.
