Selim the Sot emboldened Philip, who resolved to carry the war to the Ottoman homelands. In 1571, a mixed naval expedition of Spanish, Venetian, and papal ships led by Charles' illegitimate son Don John of Austria annihilated the Ottoman fleet at the Battle of Lepanto, in the largest naval battle fought in European waters since Actium in 31 BC. The fleet included Miguel de Cervantes, future author of the historic Spanish novel Don Quixote. The victory curbed the Ottoman naval threat against European territory, particularly in the western Mediterranean, and the loss of experienced sailors was to be a major handicap in facing Christian fleets. Yet the Turks succeeded in rebuilding their navy in a year, using it handily to consolidate Ottoman dominance over most of the Mediterranean's African coast and eastern islands. Philip lacked the resources to fight both the Netherlands and the Ottoman Empire at the same time, and the stalemate in the Mediterranean continued until Spain agreed to a truce in 1580. The time for rejoicing in Madrid was short-lived. In 1566, Calvinist-led riots in the Spanish Netherlands (roughly equal to modern-day Netherlands and Belgium, inherited by Philip from Charles and his Burgundian forebearers) prompted the Duke of Alva to conduct a military expedition to restore order. Alva launched an ensuing reign of terror. In 1568, William the Silent led a failed attempt to drive Alva from the Netherlands. This attempt is generally considered to signal the start of the Eighty Years' War that ended with the independence of the United Provinces. The Spanish, who derived a great deal of wealth from the Netherlands and particularly from the vital port of Antwerp, were committed to restoring order and maintaining their hold on the provinces. In 1572, a band of rebel Dutch privateers known as the watergeuzen ("Sea Beggars") seized a number of Dutch coastal towns, proclaimed their support for William and denounced the Spanish leadership. In 1574, the Spanish army under Luis de Requeséns was repulsed from the Siege of Leiden after the Dutch destroyed the dykes that held back the North Sea from the low-lying provinces. In 1576, faced with the costs of his 80,000-man army of occupation in the Netherlands and the massive fleet that had won at Lepanto, Philip was forced to accept bankruptcy. The army in the Netherlands mutinied not long after, seizing Antwerp and looting the southern Netherlands, prompting several cities in
