Also out of those 7 countries, Slovenia, Slovakia and Hungary were not under Russian or Turkish influence.

Where did you get that from?

As a Hungarian, I can easily tell you that that's not the case. Hungary was under Turkish rule for more than 100 years between 1526-1699. It has left deep marks on both our language and culture (sometimes good ones, like having a lot of Turkish bathhouses, but mostly just set us back quite some years).

As for Russia, Hungary was a Soviet puppet state between 1944-1989. We have a national holiday on October 23 that is a remembrance day for a failed revolution against the Soviet Union, that was shot down in a bloodbath. The current ruling party started as one of the anti-Russian parties, Orbán (our current president) literally held a speech where he was chanting "Ruszkik haza!" ("Russians go home!")... It's unfortunate that he has completely flipped since then and is now welcoming Russian influence back.

I can only assume something similar for our neighbours, but I'm happy to look it up for you.

EDIT: Also, before anyone says it, I'm not contesting that the countries in the list were under Austrian (or Austro-Hungarian) rule too. The lines are messy with whose side of the story you're reading, but as for Hungary the easy way to summarise it from the Turkish invasion is:

• Turkish rule
• Gets liberated by the Habsburgs, leading to
• Austrian rule
• Revolution, leading to getting some representation (sadly, just Hungary, not the other countries in the empire), leading to
• Austria-Hungary, leading to
• WW1
• Loads of failed governments, the great depression hits hard, leading to
• WW2, leading to
• Soviet occupation, leading to
• Failed revolutions
• Soviet Union falls, leading to
• Independent Hungarian republic, heavy anti-Russian sentiment, leading to
• Hungary tries to warm up to western powers, leading to
• Hungary joins the EU
• And now, with corruption and foreign influence going strong worldwide, Russian influence is rising again
