However, once on their new lands, Seminoles and blacks fell into strife with Creeks, who wanted control over both groups, and with Cherokees and Arkansans, who feared an enclave of free blacks near their borders. These disputes drove a wedge between the Seminoles and their black allies.
Until the Civil War, blacks were hounded by slave claims that had followed them from the East and by raids of Creeks and white slavers from Arkansas. Many blacks were captured and sold. Others fled from Indian Territory and settled in Mexico.
At the end of the Civil War, free blacks and those of African descent who had remained unemancipated were adopted into the Seminole tribe under provisions of the Treaty of 1866. They began their role in the founding of what today is the modern Seminole Nation of Oklahoma. In a preface to this edition, Littlefield explains the continuing significance of this subject.
