Great Crossings embodied monumental changes then transforming North America. The United States, within the span of a few decades, grew from an East Coast nation to a continental empire. The territorial growth of the United States forged a multicultural, multiracial society, but that diversity also sparked fierce debates over race, citizenship, and America's destiny. Great Crossings, a place of race-mixing and cultural exchange, emerged as a battleground. Its history provides an intimate view of the ambitions and struggles of Indians, settlers, and slaves who were trying to secure their place in a changing world. Through deep research and compelling prose, Snyder introduces us to a diverse range of historical actors: Richard Mentor Johnson, the politician who reportedly killed Tecumseh and then became schoolmaster to the sons of his former foes; Julia Chinn, Johnson's enslaved concubine, who fought for her children's freedom; and Peter Pitchlynn, a Choctaw intellectual who, even in the darkest days of Indian removal, argued for the future of Indian nations. Together, their stories demonstrate how this era transformed colonizers and the colonized alike, sowing the seeds of modern America.
