On Video.google, the BBC has itself posted a complete one-hour documentary, exposing the 19th-century British practice of Indentured Labour, through which more than 1 million Indian workers were transported all over the world -- only to be told there was no provision to return. They were effectively only slightly better off than the African slave laborers they were brought in to replace. The latter had been emancipated in 1833, when the British government decided to end slavery and the slave trade throughout the Empire.
The documentary is brought to you by... who else? The BBC!
Some of the speakers include Brij Lal, an Indo-Fijian who now teaches in Australia, and David Dabydeen, an Indo-Guyanan novelist who now teaches in Warwick, UK. I've watched about 25 minutes of it so far, and it seems to be pretty well designed -- some historical overview, but not too much. Most of the focus is on the descendents of Indian indentured laborers, who are now trying to work out the implications of their history.
Incidentally, it looks like this video can be downloaded for free to your PC -- in case you're going to be sitting in a train or an airport for an hour sometime this weekend, and wanted a little "light" entertainment. (You will also need to download Google's Video Player application.)
