The large Siouan tribal language group was made up of many smaller
tribes such as the Ponca, Omaha, Osage, Kansa, and Quaqaw tribes.
These five tribes once lived in an area east of the Mississippi
River, but just prior to Columbus' arrival, they had begun moving
westward. The Poncas and Omahas split from the other tribes sometime
prior to 1500. According to tradition, the Omahas and Poncas followed
the Des Moines River to its headwaters and then moved northeast.
Eventually they crossed the Missouri River and drove out the Arikara
Tribe that lived on the west bank of the Missouri River in an area
that would later be included in the state of Nebraska. Sometime
after the encounter with the Arikara, the Ponca and Omaha separated.
The separation date has been placed as early as 1390 and as late
as 1750. Certainly by 1789 the Ponca were living on lands where
the Niobrara flows into the Missouri. The Ponca Tribe was never
very large. Between 1800 and 1900, they probably never numbered
more than 800.
They appear on P. C. LeSeur's map of 1701 and were "discovered"
again by the trader Juan Baptiste Munier in 1789. By that time there
were living near the mouth of the Niobrara River. About that time
they suffered heavily from a smallpox epidemic. Lewis and Clark
esitmated that they numbered only 200 people in 1804. By 1874, they
were back up to 733 individuals, all living near the Niobrara.
Standing Bear was known to the Ponca Indian tribe as Ma-chu-nah-zah.
He was born on the Ponca reservation around 1834, although some
sources say he was born in 1829. Because he showed unusual abilities,
he became a chief at an early age.
Standing Bear, Ponca chief, date unknown.
