American students often get the impression from history classes that the British got here first, settling Jamestown, Va., in 1607. They hear about how white Northerners freed the black slaves, how Asians came in the mid-1800s to build Western railroads.

The lessons have left out a lot.

Forty-two years before Jamestown, Spaniards and American Indians lived in St. Augustine, Fla. At least several thousand Latinos and nearly 200,000 black soldiers fought in the Civil War. And Asian-Americans had been living in California and Louisiana since the 1700s.

Now, more of these and other lesser-known facts about American minorities are getting more attention. The main reason is the nation's growing diversity.
