The term "Condottieri" refers to leaders of mercenary troops in Italy during the late Middle Ages and the Renaissance. These military captains were often hired by city-states and noble families to fight in their conflicts. The condottieri played a significant role in the political and military landscape of Italy, as they could shift allegiances based on the best offers. Condottieri were known for their skills in warfare and strategy, often commanding large armies. Some famous condottieri include Francesco Sforza and Bartolomeo Colleoni. Their influence waned with the rise of national armies, but they remain a notable part of Italian history.
