Nebraska derived its name from "nebrathka," an Oto Indian word that means "flat water." It pertains to the Platte River, which was adopted in 1998 as the Nebraskan state river.
Nebraska was the 37th state that formally became part of the United States on March 1, 1867. It is situated on the western section of the north-central region of the U.S. The Platte River, which Nebraska was named after, runs its course from North Platte City towards the Missouri River, before emptying into the Mississippi River. The official nickname of Nebraska is the "Cornhusker State." Other state symbols include "Beautiful Nebraska" as the state song and "Equality Before the Law" as the state motto.
