Used to be a Spanish colony, competed with Chile over the southernmost area of South America, was ruled by some dictators known as the Rosas in the 1800s, had it's share of troubhle with Napooleon IIIs France, it's capital was known for looking European in those days, it had it's spate with facism in the depression-WW2 years and later on in the 60-70ies, tried to invade the Falkland Islands and was beaten, and the national focus today is still on conquering the Falkland Islands whenever there's news that there might be oil around there.
Oh and I think there was also a famine in the country at some point in the 90ies but that's a blurry memory of a newsreport from when I was a kid so I wouldn't bet my life on it.
