Answer:
The Byzantines, a sophisticated civilization that flourished in the Eastern Mediterranean from the 4th to 15th century, developed several innovative military technologies. These included Greek Fire, an incendiary weapon, and advanced trebuchets, a type of siege engine that could launch projectiles from a distance. Greek Fire was highly effective in naval warfare and could be projected onto enemy ships, causing destructive fires that were difficult to extinguish even on water. Byzantine forces also used counterweight trebuchets that launched projectiles, providing them with a powerful and accurate artillery weapon that could strike enemies both within and beyond their fortifications.
