Edward James Olmos narrates PBS's "Crucible of Empire: The Spanish-American War" Monday at 9. It's a look at the war that moved the United States to center stage as a world power and caused the country, founded in opposition to imperialism, to become an imperial power under President Theodore Roosevelt.

Filmed in Cuba and the Philippines, the countries where the United States had managed to oust Spain, "Crucible of Empire" tells the story of the Spanish-American War from various perspectives.

Actor Lou Diamond Phillips reads the words of Filipino rebel leader Emilio Aguinaldo, and Patrick Leahy, Paul Simon, Alan Simpson and Frank Lautenberg, all of whom have served in the U.S. Senate, recreate the Senate's heated 1899 debate over the war.

The program also features more than a dozen popular songs from the period.
