Follow up question if I may: were there any policies in the post WWII era that tried to bring back Jewish populations that had fled the country (economic or otherwise)?

Here are a couple of past threads worth checking out that will help answer your questions:

How did Jews reintegrate into Germany after being released from concentration camps in WWII?

What happened to the minds and opinions of the German people towards Jews after the fall of the Nazi Regime?

/u/estherke's contributions in particular.

Hey all,

If you frequent the sub, you know the drill. If you're here from /r/all, or browse only occasionally, please be aware we have strict rules here intended to enforce the very high bar we expect from comments, so before posting, please read our rules. We remove comments which don't comply, and consider everyone forewarned. If you have feedback or commentary about how things are run here, please don't post it in this thread. We'll just remove it. We love to hear thoughtful, constructive feedback via modmail however.

It can take time for an answer to show up, so we thank you for your patience. We know you're here because the question sounds interesting, and we eagerly await an answer just like you! While you wait though, there is tons of great content already written, which you can find through our Twitter, the Sunday Digest, the Monthly "Best Of" feature, and Facebook. If you don't want to forget to check back late, consider a Private Message to the Remind-Me bot.

Again though, please remember the rules, and keep them in mind while you browse. If you don't like how this subreddit is run, keep in mind that this method has seen us continue to succeed and grow for years, and isn't going to change, so at least try and make your complaint original. /r/AskHistory exists, so complaining about the rules to us is like going into a fancy restaurant to complain they don't sell chicken nuggets, even though Chick-fil-A is nextdoor.
