The legislative measure was an amendment to a United States declaration of war against Spain in 1898. It stipulated that the U.S. could not annex Cuba following the expulsion of Spain from the island. The declaration affirmed that the U.S. intended only to help Cuba gain its independence and would then leave control of the island to its people. For example, it restricted the United States from establishing permanent control.
This addition to the war resolution is significant because it seemingly refuted imperialistic motives for U.S. intervention in Cuba. It aimed to assure both the American public and the international community that the nation’s aim was Cuban liberty, not territorial acquisition. Its impact is debated among historians, some arguing it was a genuine expression of American anti-imperialism, while others see it as a strategic maneuver to quell opposition to the war and prevent European powers from intervening.
