How many years did the First Italian War last?

The Italian War of 1494-98 was the first of the Italian Wars, fought between the Kingdom of France against the Kingdom of Naples, which was later joined by the Papal-led "League of Venice" (Venice, Spain, Milan, the Holy Roman Empire, Florence, Mantua, and England). The war saw France conquer Naples before being forced to retreat through central and northern Italy while under attack from a large coalition of enemies. The war was the first of many wars fought in the peninsula from 1494 to 1559.
