A bit! But my knowledge is kind of unevenly distributed across Ukraine's history.
For example, I could spend quite some time talking about the Kievan Rus and the early Slavic cultures, and I could spend quite a bit more time talking about the latest conflict with Russia, and then some time in between that talking about Sevastopol and WWII, but beyond that? My knowledge of Ukraine is kind of full of blank spots.
It has one of the easiest European flags to remember, though - especially since it shares its colours with my own country, Sweden! - and I know where it is on the map. But up until this latest civil war/invasion by Russia, Ukraine hasn't really figured into my daily life a whole lot, so I haven't learned much about it.
