Sacagawea was a woman who had played a great role in the geographical history of the United States by helping Jefferson's team of Lewis and Clark who had been sent to Louisiana to explore the land after the United States had bought the land from France along with the land of New Orleans. Sacagawea's husband, whose name was Toussaint Charbonneau was a French Canadian by descent, nevertheless he understood the sign language of the Native Americans and therefore proved to be a great deal of help for the Lewis and Clark expedition as they hired him as their interpreter. The couple met the Lewis and Clark expedition during the winter their group spent in North Dakota. The reason for hiring Sacagawea was the same as her husband as she also knew the Shoshone language being a Shoshone by birth. Both husband and wife played a great role in helping the Lewis and Clark expedition in achieving their mission and at the end of it, they returned to live with the Shoshone tribe, which was the native tribe of Sacagawea.
