On the 22nd May 1942, this happened:
Filipovic is shouting “Death to fascism, freedom to the people!” — a pre-existing Communist slogan that Filipovic’s martyrdom would help to popularize. Smrt fašizmu, sloboda narodu! … or you can just abbreviate it SFSN!
In the city where Filipovic died, which is in present-day Serbia, there’s a monumental statue in his honor replicating that Y-shaped pose — an artistically classic look just like our favorite Goya painting, poised between death and victory.

Since the break up of Yougoslavia he has been claimed by all sides - Valjevo monument — it’s in Serbia, remember — calls him Stevan Filipovic, which is the Serbian variant of his given name. But as Serbia is the heir to Yugoslavia, he at least remains there a legitimate subject for a public memorial.
Filipovic himself was Croatian, but his legacy in that present-day state is a bit more problematic: in his native town outside Dubrovnik, a statue that once commemorated Filipovic was torn down in 1991 by Croat nationalists; its vacant plinth still stands sadly in Opuzen. (Opuzen’s film festival, however, awards its honorees a statuette replicating the destroyed monument.)
