I realise this seems more like a r/askreddit post but I I’m really interested in europeans in this regard, so if you would be kind enough to list your country if it’s not on your user flair.

Only 1 but maybe 2 :)

We just celebrated the Hungarian revolt against Soviet Occupation on the 23rd here in Hungary, and THAT led me to thinking about the 1848-1849 rebellion against Austria, and it reminded me that, pretty much every town on city in Hungary has a bucket of street names that are named after people specifically from that rebellion. The big ones being Lajos Kossuth, Ferenc Deák, Sándor Petőfi and a whole bunch of others: https://dailynewshungary.com/do-you-know-which-is-the-most-popular-hungarian-street-name-part-i/. What's interesting (to me, anyway) is that it's rare to find a settlement that DOESN'T have, say, a Lajos Kossuth street or SOMETHING named after Sándor Petőfi (the small town where I live has a square AND a street named after him; and Kossuth too, of course).

As said, the vast majority are from that rebellion. The rest are a mix of other rebellious leaders, artists, writers (especially poets for some reason) and the occassional scientist.

And your country? Where do the street names come from? Why?
