Tribal sovereignty is one of the most important and often misunderstood concepts in the relationship between Native nations and the United States. At its core, sovereignty means that Native nations are distinct political communities with the inherent authority to govern themselves. Understanding this idea is essential to understanding treaties, land, and the legal status of tribes today.
Inherent, not granted
A key point about tribal sovereignty is that it is inherent. Native nations governed themselves for countless generations before the arrival of Europeans, and their authority to do so does not come from the United States. Rather, tribal sovereignty predates the founding of the United States and continues to exist except where it has been limited by treaty or by acts of Congress.
This is why Native nations are often described as domestic dependent nations, a phrase drawn from early court decisions. They are nations with governmental authority, existing within the borders of the United States and in a special relationship with the federal government.
What sovereignty allows
Sovereignty gives Native nations the authority to make and enforce their own laws, to determine their own membership, to govern their territories, to run their own courts, and to manage their own affairs. Tribal governments provide services, regulate activity on their lands, and represent their peoples in dealings with other governments.
The treaties of the nineteenth century, including the 1851 and 1868 agreements at Fort Laramie, were themselves expressions of this sovereignty. The United States negotiated with Native nations as governments capable of making binding agreements, a recognition of their sovereign status.
Sovereignty and the federal relationship
Tribal sovereignty exists alongside the authority of the federal government, which holds a unique responsibility toward Native nations. This relationship is often described as a trust relationship, carrying obligations on the part of the United States. At the same time, Congress has asserted broad power over Indian affairs, and the balance between tribal authority and federal power has been worked out through generations of law and struggle.
A living principle
Tribal sovereignty is not a relic of the past but a living principle that shapes the lives of Native nations today. Modern tribal governments exercise their sovereignty in countless ways, from lawmaking to economic development to the protection of cultural heritage. Understanding sovereignty helps make sense of why treaty rights endure and why Native nations continue to assert their authority.
