The Marches, or Marche, is a region in central Italy. It was one of the regions that Cesare Borgia sought to control, hoping to extend the Papal State to this area. One way he thought he might be able to extend his control here is through the use of inventions by da Vinci. Its major boundary between the Marches and its neighbor on the west is watershed between the Tyrrhenian and Adriatic slopes. It is also bounded by the Adriatic Sea.
