Sovereignty establishes a government-to-government relationship between American Indian tribes and the United States. Exploring tribal-state interactions over land and sovereignty, this book takes a geographical look at issues of environmental regulation, expansion of gaming, criminal jurisdiction, taxation, fishing, and transportation. The contributors find repeatedly that tribes and states have two choices—litigate or cooperate. While identifying the encroachment of state jurisdiction in Indian country, this book also seeks to develop a resource for tribes, states, and all actors in their relationships and to show that no tribal-state interaction has to be a zero-sum game.
