American history can be divided into numerous eras. Let's explore the major events of those periods that shaped modern America.

From the first settling of America, the colonists had a desire to find new, undeveloped land to the west. Over time, they felt they had a right to settle from "sea to sea" under a manifest destiny.

From Jefferson's Louisiana Purchase to the California Gold Rush, this was a great time of American expansion. It shaped most of the nation that we know today.

The fascinating Prohibition Era was a time when America decided to "legally" give up drinking alcohol. Unfortunately, the experiment ended in failure with growing crime rates and lawlessness.

It was Franklin Roosevelt who brought the nation out of this period. In the process, he implemented many changes that would shape modern America.

The Cold War was a stand-off between the two major superpowers left at the end of World War II: the United States and the Soviet Union. They both tried to further their own ends by influencing nations around the world.

The period was marked by conflict and increasing tension that only resolved with the fall of the Berlin Wall and the breakup of the Soviet Union in 1991.
