Meanwhile, political and technological progress led to continuous change of tactics and equipment. Cavalry became ascendant, only to be later replaced by infantry as their weapons improved, and by the end of the period, warfare was radically changing thanks to the rise of gunpowder weapons such as the handgonne and the bombard. The Middle Ages witnessed almost constant warfare in Europe, so mercenaries were a constant on the battlefield, but the 15th century also saw the rise of mercenary usage by the increasingly wealthy aristocracy. At the time, England and France existed in smaller versions than in the modern age, while the Spanish had unified into a few large kingdoms and were slowly pushing the Moors off the Iberian Peninsula. Norway and Hungary were larger than they are now, but otherwise, most of Europe was a patchwork quilt of small, constantly warring states. This was especially true in Germany and Italy, where innumerable city-states and little fiefdoms struggled to gain more territory and defend themselves against their neighbors. The most famous came from Switzerland, which was divided into numerous small statelets called cantons, with some in the valleys and some further up in the mountains. There was a great deal of local infighting like elsewhere in Europe, but by the Late Middle Ages, unification seemed possible for a few reasons. Most notably, the Swiss felt threatened by larger outside states such as the Holy Roman Empire, France, and Milan, which were poised to take advantage of Swiss division and relative weakness to invade. The Holy Roman Empire was an especially great threat because it had some political claim over the Swiss cantons, although the Swiss had always enjoyed a great deal of independence from Hapsburg rule. Furthermore, some important trade routes ran through the region, and all the cantons would benefit if these routes were kept open and secure. One of the finest groups of mercenaries were the Landsknechts from central and northern Europe. The term means "servant of the country," and they mostly served the Holy Roman Empire, first under Emperor Maximilian I (r. 1508-1519) and then under his successors. The Landsknechts (German: Landsknechte) were masters of the battlefield, adept at pike, sword, and dead shots with the crude matchlocks of the day. The only mercenaries rivaling them were the famous Swiss, who they hated and often fought bitterly. The Landsknechts were as famous for their flamboyant costumes as much as their prowess on the battlefield, and they became symbols of rebellion and freedom in early modern Europe, even as they fought in service of Europe's largest empire. In Italy, city militias often got embroiled in the factional disputes that were rife in Italian urban politics, to the extent that the militia might take one side or another, or be so divided as to be ineffective against external enemies. The only way to avoid this was to bring in neutral, outside administrators all factions could agree on to handle local affairs in a supposedly impartial manner. Known as the podestà system, this odd method of running a government began to be common by the late 13th century, but this administration would need troops of its own and naturally hired outsiders, often non-Italians, to keep the peace. Thus was born the condottieri (singular condottiero or condottiere).
