About 100K Armenians were just made stateless and kicked out of Azerbaijan recently. You didn't hear about it because of Israel and no one cares about Azerbaijan.

These were people who predated the Soviet Union, became part of the Soviet Union, outlasted the Soviet Union, and then wanted their own country. They were living on land claimed by Azerbaijan but they understandably thought "That's a made up country. They just made it up. We can make up our own country."

Unfortunately, "living somewhere for a hundred years" doesn't count for much today. So Azeris kicked them out of their homes and they had to leave to Armenia. Azerbaijan is now eyeing Armenian territory and these people have to apply for Armenian citizenship, through no real fault of their own.
