The American Civil War began in 1861, lasting to 1865. Over two million troops from the North and up to one million troops from the South clashed over very different interpretations of individual liberty and the meaning of a "United States." The catalyst for the American Civil War was the question of slavery, and the means to fight it was mass industrialized slaughter. In its terrible wake, 365,000 soldiers of the Union and 290,000 soldiers of the Confederacy lay dead, leaving behind a specter that still haunts the United States to this day. It also left Abraham Lincoln, the Great Emancipator, with the dubious distinction of being the first US President to be assassinated. Nevertheless the United States emerged from the violence wounded but whole. The question of slavery was emphatically answered with freedom's ring and the terrible machinery of warfare could be now turned to America's economic ascendancy on the world stage.
The Homestead Act of 1862 and completion of the Transcontinental Railway in 1869 brought a massive influx of newcomers to the prairies. The number of people living on farms doubled from 10 million to 22 million between 1860 and 1880, rising to 31 million by 1905. The rising number of settlers, mountain men, industrial magnates, and tourists also created a crisis on the frontier. In 1864, Lincoln signed the Yosemite Grant, a piece of federal legislation designating the Yosemite Valley and Mariposa Grove of Giant Sequoia as a California state park. This is turn laid the groundwork for the creation of Yellowstone National Park in 1872, the first national park in the United States and the world. Yellowstone was itself only half-believed rumours through the 1860's, and it was in 1869 that Major John Wesley Powell conducted his unbelievable expedition into the Grand Canyon. These ventures only nominally protected these irreplaceable parcels of land from exploitation. 1862 also saw a gold rush in Montana... Not as iconic as the California Gold Rush of 1849 or Klondike Gold Rush of 1897, it was still this gold rush that, in part, inspired one of the first true American science fiction novels: The Huge Hunter; or, The Steam Man of the Prairies by Edward S. Ellis.
