WHEN did sakagewea die and born?

In 1800, when she was about 12 years old, Sacagawea was kidnapped by a war party of Hidatsa Indians -- enemies of her people, the Shoshones. She was taken from her Rocky Mountain homeland, located in today's Idaho, to the Hidatsa-Mandan villages near modern Bismarck, North Dakota. There, she was later sold as a slave to Toussaint Charbonneau, a French-Canadian fur trader who claimed Sacagawea and another Shoshone woman as his "wives." In November 1804, the Corps of Discovery arrived at the Hidatsa-Mandan villages and soon built a fort nearby. In the American Fort Mandan on February 11, 1805, Sacagawea gave birth to her son Jean-Baptiste Charbonneau, who would soon become America's youngest explorer.
