Filipino nationalism refers to the establishment and support of a political identity associated with the modern nation-state of the Philippines, leading to a wide-ranging campaign for political, social, and economic freedom in the Philippines. This gradually emerged from various political and armed movements throughout most of the Spanish East Indies—but which has long been fragmented and inconsistent with contemporary definitions of such nationalism—as a consequence of more than three centuries of Spanish rule. These movements are characterized by the upsurge of anti-colonialist sentiments and ideals which peaked in the late 19th century led mostly by the ilustrado or landed, educated elites, whether "peninsulares", "insulares", or native ("Indio"). This served as the backbone of the first nationalist revolution in Asia, the Philippine Revolution of 1896. The modern concept would later be fully actualized upon the inception of a Philippine state with its contemporary borders after being granted independence by the United States by the 1946 Treaty of Manila.
