Jeremiah Evarts, Cherokee Removal: The William Penn Essays and Other Writings, ed. Francis Paul Prucha (Knoxville: University of Tennessee Press, 1981). Jeremiah Evarts was a Christian missionary who strongly opposed removal and led a national campaign focused on getting American citizens to send petitions to Congress expressing their opposition to the Indian Removal Act. In addition, he wrote a series of anti-removal essays under the name of William Penn that were published in the National Intelligencer from August to December 1829. Those essays, which are brought together in this book, provide an in-depth look at the arguments made by Christian missionaries in general, and Evarts specifically, against the removal policy.
Jill Norgren, The Cherokee Cases: Two Landmark Federal Decisions in the Fight for Sovereignty (Norman: University of Oklahoma Press, 2004). Cherokee Nation v. Georgia and Worcester v. Georgia, two Supreme Court cases decided in 1831 and 1832 respectively, go a long way toward framing the larger issues related to the Cherokee struggle against removal and the forces arrayed against them. This book provides a very helpful discussion of how these cases came about and what the rulings meant for each party involved.
George Strack, George Ironstrack, Daryl Baldwin, Kristina Fox, Julie Olds, Robbyn Abbitt, and Melissa Rinehart, myaamiaki aancihsaaciki: A Cultural Exploration of the Myaamia Removal Route (Miami, OK: The Miami Tribe of Oklahoma, 2011). This short book was written and published by the Miami Tribe of Oklahoma. It does not focus exclusively on the debates over removal but examines the actual removal of the Miamis in 1846. This is a particularly good example of how present-day descendants of those who survived removal continue to tell the history of that experience.
