Louis mounted another invasion of Milan, but was defeated at the Battle of Novara, which was quickly followed by a series of Holy League victories at La Motta, Guinegate, and Flodden, in which the French, Venetian, and Scottish forces were decisively defeated. However, the death of Pope Julius left the League without effective leadership, and when Louis' successor, Francis I, defeated the Swiss at Marignano in 1515, the League collapsed, and by the treaties of Noyon and Brussels, surrendered to France and Venice the entirety of northern Italy.
