Sacagawea's story starts in 1788 when she was born into the Lemhi Shoshone people, where what is now Idaho.
At around the age of 12 Sacagawea was kidnapped by another rivaling tribe and sold to the French fur trader, Toussaint Charbonneau.
Later in 1804 while Charbonneau and Sacagawea were staying with a Hidatsa tribe, Lewis and Clark came along and requested them. as interpreters and guides on their expedition.
At the start of the expedition in 1805, Sacagawea gave birth to her son, whom she named Jean-Baptiste Charbonneau, but Clark called "Pomp".
Throughout the expedition, Sacagawea was not just a guide, but mostly helped with deciphering different plants, as well as interpreting the languages of other tribes of people they meet along the way.
Including one meeting with a Shoshone tribe, who's chief turned out to be her brother.
There are many different speculations of her death, but one, is that after the expedition with Lewis and Clark had been complete, she became sick with a common disease-typhus and later died.
