Ppanka

The Ppanka, or Ponca, were a Dhegiha-speaking people who lived near the confluence of the Niobrara and Missouri rivers. Around 1700 they built the fortified village of Nanza in present-day Nebraska. A smallpox epidemic devastated the Ponca after a trading post was established there in 1789; in 1824 Lakota attackers killed most of their leaders.
