[T]hese tales of Sacajawea are just that, tales. The true story behind Sacajawea is that her husband was part of the Lewis and Clark expedition and took her along. Sacajawea was born in 1790 in the Shoshone tribe. When she was a young girl she was taken from her family during a raid by the Hidatsa tribe and brought back to their village. Some time had passed when a trapper and fur trader came upon the village and bought Sacajawea from the tribe. He took Sacajawea in as his wife, and at the age of sixteen they joined the expedition, Sacajawea being pregnant at the time.
