Don't know about the Barbary corsairs and piracy, but in Slovenia we very much saw Ottoman invasions as an existential threat. Our history is littered with reference to "The big bad Turk who steals your kids, razes your fields, and rapes your wives".

That shit happened. Regularly. To the point that a whole cultural heritage around fortified churches developed. The peasants would retreat into their church behind battlements, and hunker down until the Ottomans left. The village would get burned down and the crops were gone, but at least almost everyone survived.

It didn't help that the Habsburg monarchy saw this as a successful strategy. Oh okay they're just burning the peasants, at least they're not getting as far as Vienna. This is working.

Of course once or twice they did get as far as Vienna and it was bad ...

This period of history left a deep seated distrust of islamic nations so strong that the whole "islam vs. catholic/orthodox" thing still featured as a driving force in the mid 90's Balkan wars. As an interesting curiosity, if you go to Bosnia around the Mostar region you can see a very interesting divide. Left side of the river littered with church spires, right side full of minarets. Barely any mixing.
