I believe the answer to your question is. <span>All food and supplies were sent to soldiers, while civilians starved at home.</span>
These countries differ in many ways: linguistically speaking, Poland an Serbia, which are slavic, do not share the same origins with Hungary, which is not an Indo-European language. Secondly, Poland and Hungary are countries which did not separate themselves, nor socially, nor geographically after 1989 when communism ceased to exist as Serbia used to belong to a bigger country, Yugoslavia, in the past.
Correct answer: HELOTS
The context of this question is the ancient Greek city-state of Sparta. Sparta was a strongly militaristic society, and so soldiers were of highest value to the city. Helots were a class of agricultural laborers that we might call "serfs" in other contexts of history later on, such as Russia. They were less than citizens, but not exactly in a status of slaves. The name "helots" is of uncertain etymology. The best guess is that it derives from a Greek word meaning "to be captured and made a servant." They were in a position of forced servitude, to produce the food supply for the Spartan state. Indeed, it was common for Sparta to issue declarations of war against the helots to keep them under control and in subjugated status.
Probably your best bet is "<span>the removal of Bosnian Serbs from political power"</span>
That they have a different culture
