History

History of Denver County

The greater Denver area was inhabited by several Indigenous peoples such as Apaches, Utes, Cheyennes, Comanches, and Arapahoes. By the terms of the 1851 Treaty of Fort Laramie between the United States and various tribes including the Cheyenne and Arapaho, the United States unilaterally defined and recognized Cheyenne and Arapaho territory as ranging from the North Platte River in present-day Wyoming and Nebraska southward to the Arkansas River in present-day Colorado and Kansas. This definition specifically encompasses the land of modern Metropolitan Denver. But the discovery in November 1858 of gold in the Rocky Mountains in Colorado (then part of the western Kansas Territory) brought on a gold rush and a consequent flood of white immigration across Cheyenne and Arapaho lands.

Part of Colorado Voter Check

This is the Denver County page of Colorado Voter Check, a project of True the Vote, pointing Colorado voters at the official tools that already exist — and at Scan Check Protect to verify your registration.

Where anything here differs from what Denver County or the Colorado Secretary of State publishes, they are right and this page is not.
