In 1816, the United Provinces of the Rio Plata declared their independence from Spain. After Bolivia, Paraguay, and Uruguay went their separate ways, the area that remained became Argentina. The country's population and culture were heavily shaped by immigrants from throughout Europe, with Italy and Spain providing the largest percentage of newcomers from 1860 to 1930. Up until about the mid-20th century, much of Argentina's history was dominated by periods of internal political conflict between Federalists and Unitarians and between civilian and military factions. After World War II, an era of Peronist populism and direct and indirect military interference in subsequent governments was followed by a military junta that took power in 1976. Democracy returned in 1983 after a failed bid to seize the Falkland Islands (Islas Malvinas) by force, and has persisted despite numerous challenges, the most formidable of which was a severe economic crisis in 2001-02 that led to violent public protests and the successive resignations of several presidents. In January 2013, Argentina assumed a nonpermanent seat on the UN Security Council for the 2013-14 term.
Argentina is a huge country, with a climate which varies from region to region. Anyone intending to spend a great deal of time there, would be best to plan their travels around following the seasons in the correct order, whilst those going for a week or two should visit places at the more suitable time. Kepp in mind that Buenos Aires is hot in the summer between November and April but cold in the winter. The Lake District is best during October and March, whilst Mendoza has a temperate climate the year through. Care should be taken when visiting Patagonia, as it is quite possible to receive all four seasons in one day, and it is best avoided during the depths of winter in June, July and August.
