Conquest (1930)
Early documentary, slung together from footage depicting the first invasion of North America by Europeans, designed to show industrial technology's role in the development of North America. Used footage from the 1923 feature "The Covered Wagon" as though it were history. Produced by the Empire Marketing Board, which was established by the Conservative Party in 1926 to promote inter-imperial trade.
