1898 was a landmark year for the United States on the global stage, one in which it made unprecedented acquisitions of overseas territories and dramatically expanded its geopolitical influence. These developments did not go unopposed, however. As author Michael Patrick Cullinane shows, hundreds of thousands of Americans rejected as imperialist their nation's foreign policy. In doing so, these dissenters established the first national anti-imperialist movement. This book offers a fresh look at anti-imperial protest, demonstrating that the American movement was not a complete failure, and indeed prefigured latter-day protest movements.
