Based on what you learned in Lesson 17 and your own Civil War technology research, which weapon or invention was the most effective both during the war and in the long term?

(Your answer should be 7 to 10 sentences long.)

The Civil War was a time of great social and political upheaval. It was also a time of great technological change. Inventors and military men devised new types of weapons, such as the repeating rifle and the submarine, that forever changed the way that wars were fought. Even more important were the technologies that did not specifically have to do with the war, like the railroad and the telegraph. Innovations like these did not just change the way people fought wars–they also changed the way people lived.
