Zebulon Pike meets with a group of Mdewakanton Dakota led by Ta Oyate Duta (His Red Nation, also called Little Crow, grandfather of the warrior of 1862) and Wanyanka Nazin (He Sees Standing Up). Pike leaves the meeting with what he sees as their permission to take 100,000 acres of their land. The agreement, however, is an informal one—not an official treaty—and is never proclaimed by a US president.
