(October 2013) Mesoamerican chronology divides the history of pre-Columbian Mesoamerica into several periods: the Paleo-Indian (first human habitationâ3500 BCE), the Archaic (3500â2000), the Preclassic or Formative (2000 BCEâ200 CE), the Classic (200 CEâ1000CE), and the Postclassic (1000 CEâ1697 CE).
John Hay called the Spanish-American War a splendid little war  because it was short but substantial. It lasted a little over three  months and resulted in the total defeat â¦ and collapse of the Spanish  Empire at the hands of the Americans.
The American Civil War was the largest and most destructive conflict in the Western world between the end of the Napoleonic Wars in 1815 and the onset of World War I in 1914. The Civil War started because of uncompromising differences between the free and slave states over the power of the national government to prohibit slavery in the territories that had not yet become states.
