This question largelly depends on what pirates you're referring to: classic yarr-harr-harr American coastal piracy or pirates of this period in general? If it's the first, I'd say it varies by country but they are still somewhat known because of their widespread presence in mass media. If it's the second, then pirates play large role in history of any country that at least has large rivers since river and lake piracy was just as common as open sea raiding since time immemorial.

Presuming you mean classic imagery people think about when hearing the word "pirate", at least in former USSR this stereotype and most well known pirates' names are known and some events are mentioned in history books (at least that was the case when I was reading them back in school ~10 years ago). Partially it's because of large amount of translated pirate-themed literature, since come of classics became very popular even in landlocked parts of USSR because of their attractive adventuring nature (Treasure Island and Captain Blood being the most obvious mentions). Treasure Island was popular enough to warrant its own cartoon mini-series in 80s.

This led to many actions of the piracy lacking context. While history books obviously mentioned toll pirate activities took on trade and how pirates were prosecuted if being caught, general image of a pirate is the one of a daring, adventurous man at odds with powerful government trying to hunt him down, almost an underdog. And underdog is widely known to be popular character archetype to root for. This was further pressed upon by movies like Pirates of the Carribean which also largelly display at least some of the pirate cast as sympathetic.

I would thus argue that in some landlocked countries or countries with limited coastal access of former USSR classic American pirates are known but details of their existence are glossed over, thus making mass media portrait to be very popular.
