Time to lay the smackdown on Hungarian history.
The Hungarians, apart from the Slavs/Turks, are one of the only people to have moved to Europe-and stayed! They conquered what was a lightly populated Slavic area and assimilated them and destroyed a state supposedly call Great Moravia, the wet dream of Western Slav nationalists. The Hungarians quickly converted to Catholicism and expanded their empire to the point of controlling half, if not more of the balkans, and chunks of Central Europe. Their biggest point, though, is not being one the only migrating people to establish themselves, quickly form a stable empire, then become a regional power that Byzantium begged for help. For a time, Hungarians actually where the Holy Roman Emperors. They also married their way into the Hapsburg dynasty(or the Austrians married into Hungary), which is how we get Austria-Hungary. Being a German, the Austrian King gave little freedom or authority to the Hungarians. Before this though, the Hungarians had been fighting the Ottomans almost continuously for decades, possibly even a century of on and off fighting. Their population stagnated as the population of other countries rocketed, making Hungary go from Great Power, to Regional Power on it's own in comparison. With Austria, it was considered a Great Power. Budapest was a center of the early Renessance, with the steam of it going along to Italy. Not only did lost information travel to Italy from Greek traders, Venice, and the rare Muslim trader, it also came from the Hungarians that had spent decades raiding the Ottoman Balkans. Next, let's talk about what the Austrians did to the Hungarians. They refused to allow them to emigrate, but encouraged Serbs migrating from Ottoman Kosovo(yep, that's the big source of this crisis), to settle in Vojvodina(is that how you spell it?), turning it from a Hungarian majority to a Serbian plurality, as the Hungarians stagnated and the Serbs increased. The Austrians continued to use mainly Hungarian divisions, meaning many Hungarians died fighting one of Austria's poorly managed wars. Did I mention that this caused their population to stagnate?

Need I also mention that Hungarian Jews where some of the biggest inventors and scientists in history, and many worked on the ATOM BOMB for America? If I remember right.......the plurality of the team working on the bomb where Hungarian.
In summary-What the Hungarians did:
-Helped build the Atomic Bomb
-Many advances in science, invention, and other advancements in technology
-Fought for centuries a near-endless war that cost them their population growth, the reason we have no more than 10 million Hungarians, when their population could possibly(on a loose guess) be close to 40 million, possibly much, much higher. Hey! Isn't that how many Italians/Spaniards there are?

-If you consider stopping the Ottoman Empire a positive thing(I don't, I'd personally revise history and have the Ottomans conquer the world

And I'm Catholic), then there's that
-Hungarians where the majority of Austrian troops in many wars under Austrian leadership
-Budapest was a staging point of the Renissance
-Where the punch behind the Austrian's talk, at the Austrian's peak
Probably more things that I could pinpoint, but I is too lazy to go find a book.
