Europeans arrived in the region with the 1502 voyage of Amerigo Vespucci. Spanish navigator Juan Diaz de Solias visited what is now Argentina in 1516. Spain established a permanent colony on the site of Buenos Aires in 1580, although initial settlement was primarily overland from Peru. The Spanish further integrated Argentina into their empire by establishing the Vice Royalty of Rio de la Plata in 1776, and Buenos Aires became a flourishing port. Buenos Aires formally declared independence from Spain on July 9, 1816. Argentines revere Gen. Jose de San Martin, who campaigned in Argentina, Chile, and Peru as the hero of their national independence. Following the defeat of the Spanish, centralist and federationist groups waged a lengthy conflict between themselves to determine the future of the nation. A modern constitution was promulgated in 1853, and a national unity government was established in 1861.
Two forces combined to create the modern Argentine nation in the late 19th century: the introduction of modern agricultural techniques and integration of Argentina into the world economy. Foreign investment and immigration from Europe aided this economic revolution. Investment, primarily British, came in such fields as railroads and ports. As in the United States, the migrants who worked to develop Argentina's resources--especially the western pampas--came from throughout Europe.
From 1880 to 1930 Argentina became one of the world's 10 wealthiest nations based on rapid expansion of agriculture and foreign investment in infrastructure. Conservative forces dominated Argentine politics until 1916, when their traditional rivals, the Radicals, won control of the government. The Radicals, with their emphasis on fair elections and democratic institutions, opened their doors to Argentina's rapidly expanding middle class as well as to groups previously excluded from power. The Argentine military forced aged Radical President Hipolito Yrigoyen from power in 1930 and ushered in another decade of Conservative rule. Using fraud and force when necessary, the governments of the 1930s attempted to contain the currents of economic and political change that eventually led to the ascendance of Juan Domingo Peron (b. 1897). New social and political forces were seeking political power, including a modern military and labor movements that emerged from the growing urban working class.
The military ousted Argentina's constitutional government in 1943. Peron, then an army colonel, was one of the coup's leaders, and he soon became the government's dominant figure as Minister of Labor. Elections carried him to the presidency in 1946. He aggressively pursued policies aimed at empowering the working class and greatly expanded the number of unionized workers. In 1947, Peron announced the first 5-year plan based on the growth of industries he nationalized. He helped establish the powerful General Confederation of Labor (CGT). Peron's dynamic wife, Eva Duarte de Peron, known as Evita (1919-52), played a key role in developing support for her husband. Peron won reelection in 1952, but the military sent him into exile in 1955. In the 1950s and 1960s, military and civilian administrations traded power, trying, with limited success, to deal with diminished economic growth and continued social and labor demands. When military governments failed to revive the economy and suppress escalating terrorism in the late 1960s and early 1970s, the way was open for Peron's return.
On March 11, 1973, Argentina held general elections for the first time in 10 years. Peron was prevented from running, but voters elected his stand-in, Dr. Hector Campora, as President. Peron's followers also commanded strong majorities in both houses of Congress. Campora resigned in July 1973, paving the way for new elections. Peron won a decisive victory and returned as President in October 1973 with his third wife, Maria Estela Isabel Martinez de Peron, as Vice President. During this period, extremists on the left and right carried out terrorist acts with a frequency that threatened public order. The government resorted to a number of emergency decrees, including the implementation of special executive authority to deal with violence. This allowed the government to imprison persons indefinitely without charge.
Peron died on July 1, 1974. His wife succeeded him in office, but a military coup removed her from office on March 24, 1976, and the armed forces formally exercised power through a junta composed of the three service commanders until December 10, 1983. The armed forces applied harsh measures against terrorists and many suspected of being their sympathizers. They restored basic order, but the human costs of what became known as "El Proceso," or the "Dirty War" were high. Conservative counts list between 10,000 and 30,000 persons as "disappeared" during the 1976-83 period. Serious economic problems, mounting charges of corruption, public revulsion in the face of human rights abuses and, finally, the country's 1982 defeat by the United Kingdom in an unsuccessful attempt to seize the Falklands/Malvinas Islands all combined to discredit the Argentine military regime. The junta lifted bans on political parties and gradually restored basic political liberties.
Democracy returned to Argentina in 1983, with Raul Alfonsin of the country's oldest political party, the Radical Civic Union (UCR), winning the presidency. Three general elections followed in the next 16 years--a remarkable feat in Argentine political history--with the Justicialist Party (PJ) candidate Carlos Menem winning two and the UCR's Fernando De la Rua one.
On October 30, 1983, Argentines went to the polls and chose Raul Alfonsin, of the Radical Civic Union (UCR), as President. He began a 6-year term of office on December 10, 1983. In 1985 and 1987, large turnouts for mid-term elections demonstrated continued public support for a strong and vigorous democratic system. The UCR-led government took steps to resolve some of the nation's most pressing problems, including accounting for those who disappeared during military rule, establishing civilian control of the armed forces, and consolidating democratic institutions. However, failure to resolve endemic economic problems, and an inability to maintain public confidence undermined the effectiveness of the Alfonsin government, which left office 6 months early after Peronist candidate Carlos Saul Menem won the 1989 presidential elections.
President Menem imposed peso-dollar parity (convertibility) in 1992 to break the back of hyperinflation and adopted far-reaching market-based policies. Menem's accomplishments included dismantling a web of protectionist trade and business regulations, and reversing a half-century of statism by implementing an ambitious privatization program. These reforms contributed to significant increases in investment and growth with stable prices through most of the 1990s. Unfortunately, widespread corruption in the administrations of President Menem and President Fernando De la Rua (elected in 1999) shook confidence and weakened the recovery. Also, while convertibility defeated inflation, its permanence undermined Argentina's export competitiveness and created chronic deficits in the current account of the balance of payments, which were financed by massive borrowing. The contagion effect of the Asian financial crisis of 1998 precipitated an outflow of capital that gradually mushroomed into a 4-year depression that culminated in a financial panic in November 2001. In December 2001, amidst bloody riots, President De la Rua resigned, and Argentina defaulted on $88 billion in debt, the largest sovereign debt default in history.
A legislative assembly on December 23, 2001, elected Adolfo Rodriguez Saa to serve as President and called for general elections to elect a new president within 3 months. Rodriguez Saa announced immediately that Argentina would default on its international debt obligations, but expressed his commitment to maintain the currency board and the peso's 1-to-1 peg to the dollar. Rodriguez Saa, however, was unable to rally support from within his own party for his administration and this, combined with renewed violence in the Federal Capital, led to his resignation on December 30. Yet another legislative assembly elected Peronist Eduardo Duhalde President on January 1, 2002; he assumed office in the midst of a widespread public rejection of the "political class" in Argentina. Duhalde--differentiating himself from his three predecessors--quickly abandoned the peso's 10-year-old link with the dollar, a move that was followed by currency depreciation and inflation. In the face of rising poverty and continued social unrest, Duhalde also moved to bolster the government's social programs.
In the first round of the presidential election on April 27, 2003, former President Carlos Menem (Justicialist Party--PJ) won 24.3% of the vote, Santa Cruz Governor Nestor Kirchner (PJ) won 22%, followed by Ricardo Murphy with 16.4% and Elisa Carrio with 14.2%. Menem withdrew from the May 25 runoff election after polls showed overwhelming support for Kirchner. President Kirchner took office on May 25, 2003. He took office following the immense social and economic upheaval stemming from the financial crisis caused by a failed currency convertibility regime. Despite widespread concern, democracy and democratic institutions survived the crisis, and Nestor Kirchner has taken firm hold as President. After taking office, Kirchner focused on consolidating his political strength and alleviating social problems. He forced changes in the Supreme Court and military and undertook popular measures, such as raising government salaries, pensions, and the minimum wage. The wave of public demonstrations that coincided with the economic downturn stabilized. On October 23, 2005, President Kirchner won a major victory in the midterm legislative elections, giving him a strengthened mandate and a stronger position in the Senate and Chamber of Deputies.
