In the 1840s, the desire for new land and the promise of riches drew thousands of Americans westward. But the journey by wagon and on foot was slow and dangerous, and people yearned for a new way to travel. The dream of creating a railroad that spanned the entire country seemed at best fleeting, but the passion of a few ignited a nation. Railroad fever had struck.

The transcontinental railroad would forever change the face of the country. Through the hard work of Irish and Chinese immigrants, former slaves, and others, the dream of transcontinental travel became a reality. Fighting rough terrain and enduring backbreaking work and terrible conditions, the workers pushed on in the "great race" that developed between the Central Pacific and the Union Pacific railroads. Part of National Geographic's Crossroads America series, Railroad Fever: Building the Transcontinental Railroad, 1830-1870 is a story of struggle, dreams, and the building of America.


After the Civil War, the South went through a period of rebuilding, termed Recon-struction, but because many white people in the South were not ready to accept African Americans as equals, unfair laws were passed which restricted the rights of blacks. These Black Codes and Jim Crow laws left African Americans adrift in a segregated world.


Life was better in the North in many ways for African Americans. The 1920s brought jobs and money—until The Great Depression hit. The Depression left many homeless and jobless. Many blacks left the cities seeking jobs wherever they could find them. Despite the hard times that followed, living in the North continued to bring a renewed sense of freedom to many African Americans.
