"Order and Disorder: 1825-1865" recalls a period of tremendous growth and ferment. Most of the new arrivals were Irish immigrants (100,000 by 1842—and that was before the potato famine), and the subsequent overcrowding led to the construction of Central Park (1857-58). But that didn't quell the ferment, which exploded in 1863 with the racially charged draft riots. "It was the largest incident of civil disorder in U.S. history," notes historian Mike Wallace.

"Cosmopolis: 1914-1931" recalls the WWI years and the "Roaring '20s" in the city that F. Scott Fitzgerald called "the land of ambition and success." Of course, an egg was laid on Wall Street in 1929, but before that happened the city gave rise, narrator David Ogden Stiers says, "to a new culture, a mass culture" that was broadcast live on radio networks headquartered in New York.
