Sacajawea was a Shoshone woman who played a crucial role as a guide and interpreter for the Lewis and Clark Expedition from 1804 to 1806. She was born around 1788 and was captured by the Hidatsa tribe when she was a teenager. Later, she was married to a French-Canadian fur trader named Toussaint Charbonneau, who was hired by the expedition. During the journey, Sacajawea's knowledge of the land and languages helped the explorers navigate through the western territories of the United States. She is often celebrated for her contributions, especially as a mother, as she carried her infant son, Jean Baptiste Charbonneau, with her throughout the expedition.
