The "Black in Latin America " Series on PBS

The series will air over four weeks on Tuesdays, April 19 and 26 and
May 3 and 10, 2011, at 8 p.m. (ET) on PBS stations. Check your local
listings for time and channel. Here are PBS's descriptions of the
series.
Episode 1: Haiti & the Dominican Republic : An Island Divided

In Haiti , The Root Editor-in-Chief Henry Louis Gates Jr. tells the
story of the birth of the first-ever black republic, and finds out how
the slaves' hard-fought liberation over Napoleon Bonaparte's French
Empire became a double-edged sword. In the Dominican Republic , Gates
explores how race has been socially constructed in a society whose
people reflect centuries of intermarriage, and how the country's
troubled history with Haiti informs notions about racial
classification.

Episode 2: Cuba : The Next Revolution

In Cuba , Gates finds out how the culture, religion, politics and
music of this island are inextricably linked to the huge amount of
slave labor imported to produce its enormously profitable 19th-century
sugar industry, and how race and racism have fared since Fidel
Castro's communist revolution in 1959.

Episode 3: Brazil : A Racial Paradise ?

In Brazil , Gates delves behind the facade of Carnival to discover how
this "rainbow nation" is waking up to its legacy as the world's
largest slave economy.

Episode 4: Mexico & Peru : The Black Grandma in the Closet

In Mexico and Peru, Gates explores the almost unknown history of the
significant numbers of black people -- the two countries together
received far more slaves than did the United States -- brought to
these countries as early as the 16th and 17th centuries, and the
worlds of culture that their descendants have created in Vera Cruz on
the Gulf of Mexico, the Costa Chica region on the Pacific, and in and
around Lima, Peru.
