- from Teddy Roosevelt
Theodore Roosevelt lived through a time of great change. His life was framed by two wars. The Civil War started two years after he was born. World War I ended two months before he died.
The Civil War was fought with muskets, bayonets, and officers on horses. World War I was fought with machine guns, tanks, and airplanes. Between 1858 and 1919, the U.S. population moved from the country to the cities. That’s because people left farms to take factory jobs. Immigration also made the population grow. Meanwhile, businessmen became richer and more powerful.
