South America is a continent situated in the western hemisphere and, mostly, the southern hemisphere, bordered on the west by the Pacific Ocean and on the north and east by the Atlantic Ocean; North America and the Caribbean Sea lie to the northwest.
As part of the Americas like North America, South America is named after Amerigo Vespucci, who was the first European to suggest that the Americas were not the East Indies, but a New World unknown to Europeans.
The continent, like many others, became a battlefield of the Cold War in the late 20th century. The government of Chile was overthrown in the early 1970s, as a late (and peculiar) development of theU.S. Monroe Doctrine. Throughout the 1980s and 1990s, Peru suffered from internal conflicts (see Túpac Amaru Revolutionary Movement and Shining Path). Other revolutions and military dictatorships have been common, but starting in the 1980s a wave of democratization came through the continent, and democratic rule is widespread now. Allegations of corruption remain common, and several nations have seen crises which have forced the resignation of their presidents, although normal civilian succession has continued.
