>Anger over that is what led them to join the Axis in WW2.
It's not that we were a bit butthurt and so we decided to join Germany. It's a history general, so let me give you a quick rundown of our history:
>895-1000
We come to the Carpathian basian as Eurasian horsenomads, pillage Europe for a few decades, but we are sandwiched between the Holy German Empire and Byzantium. So our ruler decides it's better to take up the Christianity of the later, asks for knights from the German emperor, and turns these lands into the Kingdom of Hungary, independent from both powers. The land itself had previous populations, mostly Slav tribes and remnants of previous nomad powers, like Huns and Avars. They were either enslaved or joined the Hungarian tribal alliance.
>11th to 16th centuries
We are a weird steppe empire playing the role of a feudal European kingdom. Weird, because our feudalism is pretty much the same you could find in any steppe empire. E.g. getting into the nobility was rather easy if you were talented a bit lucky; and we had whole peoples who were specialists. We had lots of German towns, because our kings knew that the Germans had towns that were full of money, so they invited German settlers to build their towns here, and then get taxed. Then there was the idea of collective nobility: certain peoples had collective rights, usually they were exempt from all taxation, but had to serve the king in every war. The best example are the székelys of Transylvania: they were border guards even before we turned into a kingdom in 1000, and kept the role until the Habsburg times. But there were "legit" Eurasian nomad peoples in the middle of the country whose only purpose was to serve as light cavalry.
Culturally and politically we are getting more and more European. E.g. our Christianity was bogstandard Catholicism without any weird cults or strange pagan. We took part in European dynastic politics of wars and marriages. We even have a crusade of our own! Although it was just a king going to the Holy Land for a vacation. Also, Croatia kinda-sorta became part of Hungary. They were an independent kingdom with their own legislature and nobility, but the king of Hungary automatically became the king of Croatia, and the actual leader of Croatia was a man selected by the king of Hungary.
>16th to 18th centuries
As all it was going on, the Ottoman Empire got stronger, conquered most of Byzantium, including the Balkans, and ended up next to our borders. Now, I want to be quick here, so I won't tell you about the life and death of king Matthias, and the consequences of getting rid of the Black Army and purposefully making a weak man the king. The important part here is that a few noble families managed to fuck everything up so much that the Turks killed the king and destroyed his army at the battle of Mohács. Then a good third of their country ended up under their rule (the middle part in the map); Transylvania with some additional territories became a principality, with the leader being nominally an underling of the Turkish sultan,;and due to dynastic marriages the throne of Hungary belonged to the Habsburgs after this, and so they got the western and northern parts.
For more than 150 years the population barely grew, meanwhile in Europe there was a population boom due to better technologies and economic life. It's because even when there wasn't an active war going on, raids and small clashes were constant, and so building any kind of economy was hard. Still, the people living in the parts conquered by the Turks didn't became Turkish, mostly because they exiled or executed anyone who got too cozy with them. Although even it's not that simple, because they were nobles who choose to side with the Turks against the Habsburgs. You see, the Habsburgs weren't the best and kindest rulers during these times. But I digress. So, the population of the lands conquered by the Truks didn't grow, but they started to live in towns instead of small villages, and preferred semi-nomad animal husbandry over agriculture. Towns were better protected from raids, and it was easier to protect a herd from a marching army that would just trample your crops. Also, Transylvania was doing a lot better, but the Turks had a tendency to send in Tartars when the ruler got uppity, and they tended to slaughter and enslave everyone they found, and that had a rather bad effect on their demographics. More on that later.
