@premierrarecoins: 400 Years old Shipwreck Recovery at Mel Fishers Treasures The Spanish arquebus was a 15th-century matchlock innovation that transformed European warfare and exploration. Adopted by the Spanish Empire, it replaced the crossbow and became one of the first practical powder-age technologies used in battles, conquests, and defense of colonial holdings. Often seen during the Age of Exploration and the rise of Spain as a global power, the arquebus represents the transition from medieval arms to the early modern era of military history.
