Sacagawea was born in Idaho in 1789. She was a part of the Shoshone tribe. They lived along the Bitterroot Range of the Rocky Mountains.
They usually had a very calm and peaceful life, but one day they got disturbed. Another nearby tribe was raiding their tribe. They tried to fight back, but they didn't suceed. Many gave up and ran to go hide. Some weren't so lucky and got captured. Sacagawea and her friend were captured, but her friend escaped, leaving her on her own. Her friend never came back for her.
The tribe took her back to their ruler. The ruler forced her to marry him, even though he was atleast three times as old as she was. By the age of 15, she was expecting her first child. While she was pregnant, she went on an expedition with Meriwether Lewis and William Clark.
They used her as their translator, so the other tribes and people could know they weren't there to harm them. They were on a journey, not attacking for war. On February 11, 1805 she gave birth to a little boy who she named Jean Baptiste. She had to do everything with her baby attached to her back in a "backpack".
Sadly, she soon became very ill with a high fever. Everyone was frightened and concerned because she was very important to their trip. They couldn't communicate to the tribes and people around them. Sacagawea finally felt better on June 24. Soon after that, they explored farther and came across the Shoshone tribe. Sacagawea was used to translate for Lewis and Clark.
Finally, they returned home and Sacagawea had her second baby. This time it was a girl, who she named Lisette. After giving birth, Sacagawea died. Clark promised to take care of her two children. Taking on the challenge of two small children with no help was a challenge, but it must have been worth it.
