BUENOS AIRES, Jan 24 (Reuters) - A sharp slide in Argentina's currency has rekindled fears of a broader crisis in a country that has suffered a series of economic and political meltdowns going back to the 1930s.
In the early 20th century, the South American country was one of the world's richest, thanks to its production of beef, wheat and other farm goods, plus an educated workforce made up mostly of European immigrants and their descendants.
But the constant crises - most of them attributable to government mismanagement and fluctuating commodities prices - have left millions in poverty and put the country off-limits to all but the most daring investors today.
Here are some of Argentina's crises through history:
The Great Depression hit Argentina especially hard, as demand in Europe and United States for its farm exports suddenly dried up. As customs revenues plunged, the government had trouble paying public workers - causing unrest to grow.
Fed up with the crisis, the military staged a coup in 1930 against democratically elected President Hipolito Yrigoyen, setting a precedent for throwing out governments in times of economic trouble. For the remainder of the 20th century, more generals (14) than civilians (11) would run the country.
President Juan Peron, a populist who drew his support from Argentina's poor and working class, oversaw a period of relative prosperity following World War Two. Factory workers received paid vacations and unions gained unprecedented power as the economy grew at an annual pace of nearly 6 percent.
However, by the early 1950s, the good times came to an end as commodity prices fell once again. Peron's nationalizations of British-owned railroads and other property antagonized business leaders and caused investment to dry up.
Inflation soared to 40 percent and real wages plunged. The death in 1952 of Peron's wildly popular first lady, Eva, known as "Evita," weakened him further. Three years later, as labor strikes paralyzed the country, Argentina's military intervened again and sent Peron into exile.
Argentina's economy failed to stabilize under a succession of military and democratic governments that implemented wildly different policies. Between 1930 and 1983, presidents averaged only two years in office while the lead minister for economic affairs was replaced at a pace of once a year.
By the 1970s, many Argentines with warm memories of postwar prosperity were clamoring for the military to allow Peron to return home. The generals relented, and Peron assumed the presidency once again. But he was unable to heal either the economy or the increasingly violent fissures in Argentine society, and Peron died of heart failure just a year later.
Various armed factions struggled for control under Peron's successor - his third wife, a former nightclub dancer he had met in Panama. In early 1976, as annual inflation surpassed 600 percent, the generals staged yet another coup.
Ensuing years would see rising inequality and an explosion in Argentina's foreign debt, as well as the deaths of up to 30,000 suspected leftists as the military tried to snuff out dissent in the so-called "Dirty War."
Democracy returned to Argentina in 1983 - this time to stay. With the armed forces disgraced by widespread human rights abuses and poor economic management, a vast majority of Argentines deemed the armed forces unfit for power, an opinion that still prevails today.
However, that didn't mean stability.
Under President Raul Alfonsin, public payrolls swelled while government revenues remained stagnant. In 1989, only 30,000 out of 30 million Argentines paid any income taxes.
That year, inflation reached an unprecedented 5,000 percent, rising so fast that some supermarkets read prices out over intercoms rather than bothering to update price tags.
As strikes swept the country and rioters looted supermarkets for food, Alfonsin decided to hand over power five months early to his elected successor, Carlos Menem.
Menem spent the 1990s cultivating foreign investment, slashing import tariffs, and privatizing money-losing state enterprises. Inflation fell to single digits, and Argentina was for a time hailed as a poster child for free-market reforms by the International Monetary Fund and others.
By the time Menem left office in 1999, however, rampant corruption was scaring off many investors. Contagion from financial crises in East Asia and Russia caused capital to rush out of Argentina almost as quickly as it had come in. The currency peg that Menem used to tame inflation became untenable as the government, unable to print money, borrowed it instead.
In 2001, unemployment soared beyond 20 percent, and reports surfaced of widespread hunger and malnutrition in a country that had long prided itself as being one of the world's bread baskets.
When another wave of riots and looting reached the capital, Menem's successor, Fernando de la Rua, resigned - kicking off a period that would see five presidents in just two weeks.
Before the crisis ended, the economy had shrunk by a fifth and thousands of young, educated Argentines had emigrated to their grandparents' ancestral homes in Europe. The government also stopped payment on more than $100 billion in debt - the world's biggest-ever sovereign default.
Since the default, Argentina has remained cut off from foreign capital markets and is considered a pariah by most investors. But the economy has also defied doomsday predictions by Wall Street analysts and others, and has by some measures experienced its best run of growth since the 1940s.
Most economists credit high prices for Argentina's soy and other commodities, due largely to demand from China.
However, many have warned the relative prosperity is unsustainable because of inflation above 20 percent and heavy government spending. President Cristina Fernandez, who has cited Eva Peron as her inspiration, frequently antagonized farmers and other investors at home and abroad.
By late 2013, as foreign reserves plunged by a third, real wages stagnated and China's demand for commodities slackened. Fernandez was implementing ever more strict capital controls, and some economists predicted a new crisis was at hand.
Those fears were accentuated by a 11 percent drop in the currency on Jan. 23, which raised the specter of even higher inflation later in 2014. However, other hallmarks of past Argentine crises - such as social unrest, labor strikes and an empowered political opposition - were notably absent.
