After the Seven Years’ War, the Spanish Empire entered into a quickening spiral of internal and external changes. International rivalries accelerated internal adjustments in the relationship between society and an increasingly bureaucratic, intrusive, and demanding state. Internal and international conflicts resulting from the late-eighteenth-century wars and the Napoleonic invasion culminated with the crisis of the American empire and the emergence of independent republics all over the Spanish America. It was in those decades that the system of three colonies that would survive until the end of the Nineteenth century—Cuba, Puerto Rico, and the Philippines—was established. In the following decades, the three remaining overseas possessions would be sites of enormous changes. The Spanish monarchy put renewed emphasis on military might, giving its authorities a praetorian standing and skirting the edges of the liberal constitutionalism that ruled the Peninsula since 1836–1837. Cuba became critically important as the world’s greatest sugar-producing region, whose wealth was the result of vast plantations worked by slaves and indentured laborers imported (despite abolition) by British, French US and Spanish vessels. Meanwhile, In parallel, the Philippines became a major tobacco grower, the center of commerce with Asia, China in particular . The crisis of slavery in the Antilles after three wars of independence (1868-1898) and the subsequent political paralysis owing to the lack of reforms weakened Spain’s position as a colonial power in the last third of the nineteenth century. The US intervention of 1898, which coincided with anti-imperialist revolutions in Cuba and the Philippines, forced Spain to definitively withdraw, putting an end to its transatlantic nexus and to the Spanish nation’s identity as an American and Asian country.
