I appreciate that the European Handball Federation (EHF) reguarly posts the results of disciplinary and arbitration hearings. Why? Because it’s transparent and much better than sweeping things under the rug. In contrast, some Federations (cough, cough, USA Team Handball) choose to keep things 100% quiet as if a violation or the need for a review of a violation never even happened. That said, sometimes the EHF posts are only partially transparent as they often are vague and have me asking, “What the hell are they talking about?”

Matej Mandić’s Unauthorized Flag Display at the 2026 Euros Medal Ceremony

Case in point is this recent EHF case

There are obvious questions here like:

• What flag?
• Why is the flag controversial?
• Was there some sort of confrontation associated with the display.

I’m not a diehard vexillologist, but I’m genuinely curious in the study of flags so finding the answers took me down a rabbit hole. At least AI made finding the answer a little bit easier. But, only a little bit, because in the fractured world of post Yugoslavia there are a lot of flag controversies to sort out. And, they have been going on even before the split. Back in 2010, I wrote about the 1990 Vlade Divac flag incident and the brilliant ESPN 30 for 30 documentary that chronicles how it ended his close friendship with Drazen Petrovic. Did something similar happen I wondered?

The Rabbit Hole and the Controversial Flag Explained

My initial thought was that the flag probably had something to do with the Ustaše because there had been some other issues recently with a singer, Thompson playing an ultra-nationist anthem at a handball celebration in Zagreb. I won’t get into a big discussion on the Ustaše but this organization had ties to Nazi Germany which by definition is controversial.

However, simple google searches didn’t turn anything up. It even took me awhile to find a good photo of the Croatian National Team 2026 European Championships Medal Ceremony. However, there is one in an obvious place, Matej Mandić’s Instagram page.

At first glance I didn’t see a big capital “U” in any of the flags nor did any of the crests start with a white box instead of a red box which internet sources say are a dog whisle for Ustaše support. Although, I did notice the flag on the far left had just a half red box and the crest was different. And, sure enough, Matej Mandić is right there smiling above that crest. But, what the hell does JUB OSKI mean?

Well, this is where Chat GPT did me a solid to explain that the modified crest is the same crest that was the flag of the short lived Croatian Republic of Herzeg-Bosnia and that JUB USKI was likely linked to the Bosnia Herzegovina town of Ljubuški. It turns out that Mandić is from Ljubuški, a Bosnian town very near the Croatian border with a mostly Croatian population. And, at some point he chose to play for Croatia instead of Bosnia Herzegovina.

I have no idea as to whether Mandić is some sort of miliant Croatian advocating for that part of Bosnia Herzegovina to be annexed by Croatia or just someone who’s simply really proud to be from Ljubuški. I suspect it’s the latter. The Wikipedia article on Ljubuški states,

Today, around 700 Bosniaks live permanently in Ljubuški again, whereby the well-functioning coexistence with the Croats is considered exemplary for the whole of Bosnia and Herzegovina

I don’t have any reason to doubt that. The Wikipedia article on the flag notes that the flag is not official, but implies that it is accepted by many as an unofficial flag of Bosnia and Herzegovina’s Croats. Perhaps more a flag of pride then an in your face nod to a facist past. I could be reading that wrong, but that’s the way I read it.

However, if you ever talked to anyone from the former Yugoslavia or even more specifically, Bosnia and Herzegovina, you’ll quickly discover that the situation there is complicated and hard to fully understand. Most times… they don’t even want to talk about it because it’s sensitive, complicated and hard to explain. That flag is probably bound to upset someone.

Handled Correctly, but Lacking Context

And, the simple and proper way to avoid such controversy is to make sure everyone sticks with the official flag of their country. The EHF has got that right. I just wish they would provide a brief explanation because failing to provide one just creates more questions. Has folks wondering what’s being hidden.
