he War 1812 is a two-hour film history of a deeply significant event in North American and world history. The war shaped American, Canadian and British destiny in the most literal way possible: had one or two battles or decisions gone a different way, a map of the United States today would look entirely (and shockingly) different. The fires of this war forged the nation of Canada; at the same time, the result tolled the end of Native American dreams of a separate nation. By war's end, the process of Native nation removal had already begun in the southeast, paving the way for a Cotton Kingdom powered by slavery, and a United States that had been on the verge of collapse was ready to announce its arrival as a global power. The U.S. did not win the War of 1812, but the noble experiment of democracy had managed to survive intense pressure from without, and within.
