Tribal Sovereignty Explained for Students and Teachers

Ask a room of high school students what tribal sovereignty means and most will either shrug or describe it as a special privilege. Both answers miss the point. Tribal sovereignty is the inherent right of Native nations to govern themselves, and it existed long before the United States did. Understanding it is the key to making sense of almost every modern Indigenous issue, from water rights to policing to language schools.

This guide is written for students, teachers and anyone who wants a clear grounding. It covers where sovereignty comes from, the court cases that shaped it, what tribes govern today, and where the limits imposed by Congress and the courts still bite.

What tribal sovereignty means

Sovereignty is the authority of a people to govern themselves. For tribes, it is inherent, meaning it was not granted by the United States. Native nations governed their own territories, made laws, settled disputes and signed treaties with European powers for centuries before 1776. When the United States made treaties with tribes, it did so government to government, which is itself a recognition that tribes were nations.

Today the federal government recognizes 574 tribal nations. Each has its own government, and many have written constitutions, elected councils, courts and police. Others govern through traditional structures such as clan systems or councils of elders. Some tribes are recognized only by their states, and some remain unrecognized, which affects their legal standing in important ways.

The court cases that shaped tribal sovereignty

Much of the legal framework comes from a handful of Supreme Court decisions. Teachers often start with three from the 1820s and 1830s, known together as the Marshall Trilogy after Chief Justice John Marshall.

Johnson v. M'Intosh (1823) applied the so-called Doctrine of Discovery, holding that tribes could sell land only to the federal government. It is still cited and still deeply criticized.
Cherokee Nation v. Georgia (1831) described tribes as "domestic dependent nations," a phrase that shaped later law.
Worcester v. Georgia (1832) ruled that state laws had no force inside Cherokee territory. President Andrew Jackson ignored it, and Cherokee removal followed within six years.

Later decisions cut sovereignty back. In Lone Wolf v. Hitchcock (1903), the Court said Congress could break treaties on its own authority, a power known as plenary power. In Oliphant v. Suquamish (1978), it held that tribal courts cannot prosecute non-Native people for crimes, even on tribal land.

Some recent cases have moved the other direction. In McGirt v. Oklahoma (2020), the Court held that the Muscogee (Creek) Nation's reservation was never disestablished by Congress, so it still exists for purposes of federal criminal law. Writing for the majority, Justice Neil Gorsuch put it plainly: the United States must be held to its word.

What tribes govern today

Tribal governments carry out a wide range of functions that most people associate only with states or cities. In practice, that includes:

Membership. Each nation decides who its citizens are, using its own criteria.
Courts and law. More than 300 tribal courts handle civil disputes, family matters and many criminal cases involving Native people.
Education. Tribes run schools, language immersion programs and 30 or more tribal colleges.
Land and environment. Many tribes set water quality standards, manage forests and fisheries, and regulate land use on their territory.
Health. Under self-governance compacts, many tribes now run their own clinics and hospitals rather than relying on federal staff.

The shift toward tribes running their own programs grew from the Indian Self-Determination and Education Assistance Act of 1975, which allowed nations to take over services the federal government had been delivering, along with the funding. Many observers consider it one of the most successful federal Indian policies of the last century, precisely because it put decisions back in tribal hands.

Why sovereignty is not a special privilege

A common classroom framing treats tribal rights as benefits the government chose to hand out, like a program that could be expanded or cut. I think that framing does real damage, and it is worth correcting directly. Tribal rights mostly come from two sources: the inherent authority tribes held before any treaty, and the specific promises the United States made in exchange for enormous land cessions. Hundreds of millions of acres changed hands under those agreements.

Seen that way, honoring sovereignty is not generosity. It is keeping a contract. Students who grasp that distinction tend to understand fishing rights disputes, pipeline protests and jurisdiction fights much more clearly, because they stop asking "why do tribes get this" and start asking "what was agreed." It is one of several framing problems discussed in our piece on what schools still get wrong teaching this history.

Where the limits still matter

Sovereignty in practice is incomplete. Because of Oliphant, for decades tribal police could do little when a non-Native person committed a crime on tribal land, which contributed to very high rates of violence against Native women. Congress partly restored tribal authority over certain crimes by non-Native people in the 2013 and 2022 reauthorizations of the Violence Against Women Act, but gaps remain.

Jurisdiction is also split by geography. Public Law 280, passed in 1953 during the termination era, handed criminal jurisdiction on many reservations to six states, including California and Minnesota, without tribal consent. Tribes in those states often deal with county sheriffs who have little funding or training for reservation work.

Land is the other major limit. Allotment policy between 1887 and 1934 broke up reservations and cut Native landholding from about 138 million acres to roughly 48 million. Checkerboard ownership still makes it hard for tribes to manage their own territory, which is part of what the Land Back movement is responding to.

How to teach tribal sovereignty well

Start with a specific nation. Use the government, constitution or court system of a tribe near your school rather than speaking about "Native Americans" in general.
Read a treaty. Many treaties are short. Reading the actual text shows students that these were negotiated agreements between nations.
Connect to current news. A water rights case or a tribal election makes sovereignty concrete.
Use Native sources. Tribal websites, Native journalists and tribal college scholars give perspectives textbooks often lack. Our guide to finding reliable sources on Indigenous history can help.

Frequently asked questions

Do tribes have the same powers as states?

Not exactly. Tribes hold inherent powers states do not, such as defining their own citizenship, but Congress and the courts have limited some tribal authority, especially over non-Native people. In many areas, tribes and states share or dispute jurisdiction, which is why each situation has to be looked at closely.

Are Native Americans citizens of the United States?

Yes. The Indian Citizenship Act of 1924 made Native people born in the United States citizens. Many are also citizens of their own tribal nations, holding dual citizenship.

Can a state tax or regulate a tribe?

Generally, states cannot directly tax or regulate tribes or tribal members on their own reservations without congressional permission. There are exceptions, and the rules can change when non-Native people or businesses are involved. Courts continue to decide these questions case by case.
