On October 12, 1492, an Italian navigator dropped anchor on a small island in the Caribbean, firmly believing he had arrived in India. He was Columbus. Exactly 423 years passed from that day until the opening of the Panama Canal in 1914. During that time, the United States rose from a land where even its discovery was ignored to a superpower that determines the fate of the world. This video is a comic documentary that unravels the chain of cause and effect over those 423 years through 13 decisive moments. Columbus's first report, the dividing line on the desks of Spain and Portugal, the beginning of Britain's late colonization, the French and Indian War, the Declaration of Independence on July 4, 1776, Washington's inauguration in 1789, the hidden negotiations behind the Louisiana Purchase in 1803, the Mexican-Texas War, the Gold Rush, Lincoln's election in 1860 and the Civil War, 4 a.m. on the Alaska Purchase in 1867, the truth behind the explosion of the USS Maine in 1898, and finally, the opening of the Panama Canal in 1914.
