Political intrigue within the Church in the mid-14th century caused the Western Schism. During this forty-year period, two popes—one in Avignon and one in Rome—claimed rulership over the Church. Although the schism was eventually healed in 1417, the papacy's spiritual authority had suffered greatly. In the 15th century, Europe started to extend itself beyond its geographic frontiers. Spain and Portugal, the greatest naval powers of the time, took the lead in exploring the world. Exploration reached the Southern Hemisphere in the Atlantic and the Southern tip of Africa. Christopher Columbus reached the New World in 1492, and Vasco da Gama opened the ocean route to the East linking the Atlantic and Indian Oceans in 1498. Ferdinand Magellan reached Asia westward across the Atlantic and the Pacific Oceans in the Spanish expedition of Magellan-Elcano, resulting in the first circumnavigation of the globe, completed by Juan Sebastián Elcano (1519–1522). Soon after, the Spanish and Portuguese began establishing large global empires in the Americas, Asia, Africa and Oceania. France, the Netherlands and England soon followed in building large colonial empires with vast holdings in Africa, the Americas, and Asia. A year later England tried unsuccessfully to invade Spain, allowing Philip II of Spain to maintain his dominant war capacity in Europe. This English decisive disaster also allowed the Spanish fleet to retain its capability to wage war for the next decades.
