The United States, a rising power proclaiming liberty and progress, cast itself as a champion of freedom in an age of crumbling empires. In 1898, under the banner of avenging the destruction of the USS Maine and in defense of Cuban independence, the nation entered into sudden and deliberate war with the Spanish Empire. Now engaged on distant shores, the United States Navy secures victory in the Caribbean and the Pacific, while American forces occupy former Spanish holdings. In the Philippines, where Filipino revolutionaries had already risen against colonial rule, U.S. troops now find themselves entangled—first as liberators, then as occupiers—facing a new and bitter struggle as the Philippine Revolution transforms into a war for independence against American expansion.
