In 1517 Martin Luther issued his “Ninety-five Theses,” launching the Protestant Reformation; just five years later, Ferdinand Magellan’s expedition sailed around the globe, shattering European notions of terrestrial geography. Within a few short years, old medieval certainties about Heaven and earth began to collapse. In the ensuing decades, Europeans struggled to come to terms with religious difference at home and the multitudes of new peoples and places they encountered abroad. While some Europeans were fascinated and inspired by this new diversity, too often the result was violence. Europeans endured decades of civil war between Protestants and Catholics, and indigenous peoples suffered massive population losses as a result of European warfare, disease, and exploitation. Tragically, both Catholic and Protestant religious leaders condoned the African slave trade that brought suffering and death to millions of people.
Even as the voyages of discovery coincided with the fragmentation of European culture, they also played a role in longer-term processes of state centralization and consolidation. The new monarchies of the Renaissance produced stronger and wealthier governments capable of financing the huge expenses of exploration and colonization. Competition to gain overseas colonies became an integral part of European politics. Spain’s investment in conquest proved spectacularly profitable and yet, as we will see in Chapter 15, the ultimate result was a weakening of its power. Over time the Netherlands, England, and France also reaped tremendous profits from colonial trade, which helped them build modernized, centralized states. The path from medieval Christendom to modern nation-states led through religious warfare and global encounter.
