Americans' eagerness to expand westward prompted a long series of American Indian Wars. The Louisiana Purchase of French-claimed territory in 1803 almost doubled the nation's area. The War of 1812, declared against Britain over various grievances and fought to a draw, strengthened U.S. nationalism. A series of military incursions into Florida led Spain to cede it and other Gulf Coast territory in 1819. The expansion was aided by steam power, when steamboats began traveling along America's large water systems, many of which were connected by new canals, such as the Erie and the I&M; then, even faster railroads began their stretch across the nation's land.
Most settlers in every colony were small farmers, though other industries were formed. Cash crops included tobacco, rice, and wheat. Extraction industries grew up in furs, fishing and lumber. Manufacturers produced rum and ships, and by the late colonial period, Americans were producing one-seventh of the world's iron supply. Cities eventually dotted the coast to support local economies and serve as trade hubs. English colonists were supplemented by waves of Scotch-Irish immigrants and other groups. As coastal land grew more expensive, freed indentured servants claimed lands further west.
More InfoThe New York Times reported on April 3, that some members of the special counsel had told associates that they believe Barr's letter did not adequately portray their findings, which they considered to be more troubling for Trump than reported. The next day, The Washington Post reported that members of Mueller's team, who spoke anonymously, reported that the evidence gathered on obstruction of justice was "much more acute than Barr suggested." These members of Mueller's team revealed that they believed that the evidence showed Trump obstructed justice, but that the entire team could not draw a conclusion because they were split over the evidence and law. The Washington Post report did not explain why they believed their findings to be more serious than Barr's conclusions and it is unknown how many members of the special counsel hold these opinions.
More InfoOn March 22, 2019, the special counsel's office concluded their investigation and sent a report to the Department of Justice where it was received by Attorney General William Barr. Barr, at Trump's nomination, had become Attorney General on February 14, 2019, gaining oversight of the investigation from Trump-appointed Acting Attorney General Matthew Whitaker. Whitaker had assumed oversight from Rosenstein on November 7, 2018, after the resignation of then-Attorney General Jeff Sessions, who had recused himself from the investigation. Both Barr and Whitaker had been critical of the Mueller investigation before their appointments. Barr has faced bipartisan pressure to release the full report to the public, to the maximum extent permissible by law.
More InfoEstimating the native population of North America at the time of European contact is difficult. Douglas H. Ubelaker of the Smithsonian Institution estimated that there was a population of 92,916 in the south Atlantic states and a population of 473,616 in the Gulf states, but most academics regard this figure as too low. Anthropologist Henry F. Dobyns believed the populations were much higher, suggesting 1,100,000 along the shores of the gulf of Mexico, 2,211,000 people living between Florida and Massachusetts, 5,250,000 in the Mississippi Valley and tributaries and 697,000 people in the Florida peninsula.
More InfoThe first known use of the name "America" dates back to 1507, when it appeared on a world map created by the German cartographer Martin Waldseemüller. On this map, the name applied to South America in honor of the Italian explorer Amerigo Vespucci. After returning from his expeditions, Vespucci first postulated that the West Indies did not represent Asia's eastern limit, as initially thought by Christopher Columbus, but instead were part of an entirely separate landmass thus far unknown to the Europeans. In 1538, the Flemish cartographer Gerardus Mercator used the name "America" on his own world map, applying it to the entire Western Hemisphere.
