What are five ways that the civil war changed the nation

1. We have ambulances and hospitals.

Before the war, most people received health care at home. After the war, hospitals adapted from the battlefront model cropped up all over the country. The ambulance and nurses' corps became fixtures, with the Civil War's most famous nurse, Clara Barton, going on to establish the American Red Cross. Today's modern hospital is a direct descendant of these first medical centers.

2. We prize America as a land of opportunity.

The Civil War paved the way for Americans to live, learn and move about in ways that had seemed all but inconceivable just a few years earlier. With these doors of opportunity open, the United States experienced rapid economic growth. Immigrants also began seeing the fast-growing nation as a land of opportunity and began coming here in record numbers.

3. We let technology guide how we communicate.

Abraham Lincoln was a techie. A product of the Industrial Revolution, Lincoln is the only president to have held a patent (for a device to buoy boats over shoals). He was fascinated with the idea of applying technology to war: In 1861, for example, after being impressed by a demonstration of ideas for balloon reconnaissance, he established the Balloon Corps, which would soon begin floating hot-air balloons above Confederate camps in acts of aerial espionage.

4. We identify ourselves as Democrats and Republicans.

Before 1854, you might have been a Whig. Or a Free Soldier. But that year the Republican Party was founded by anti-slavery activists and refugees from other political parties to fight the iron grip of powerful southern Democrats.

5. We hold certain rights to be sacred.

Before the Civil War, the concept of liberty and justice for all meant little unless you were white and male. Going beyond the abolition of slavery, the 14th and 15th amendments were the first extensions of citizenship and voting rights to minority groups.
