History & details First built by Chinese in 200s A.D. Idea spread to Europe by 1200s Siege weapon used in Medieval Europe to break down walls Could throw stones weighing up to 300 pounds

Importance Used in Medieval Europe to break down castle walls & destroy buildings Simple to build, use, & maintain Allowed armies to safely attack castle walls Primary weapon used in siege warfare until 1500s Made obsolete by gunpowder weapons like cannons
