Belgrade

Belgrade is the capital and largest city of Serbia, with a population of roughly 1.7 million in the city proper. It sits at the confluence of the Sava and Danube rivers and has stood for centuries at the crossroads between Central Europe and the Balkans, a position that has made it both a strategic prize and a perennial frontier. It was the capital of successive South Slav states across the twentieth century, serving as the seat of the Kingdom of Yugoslavia and then of socialist Yugoslavia, before becoming the capital of an independent Serbia after that federation's breakup.

The city's modern history is bound up with that breakup. Belgrade was the political centre of Slobodan Milosevic's Serbia during the Yugoslav wars of the 1990s and was struck by NATO air raids during the 1999 Kosovo campaign. Today it anchors a Serbia that has charted a deliberately non-aligned course: a candidate for European Union membership that has nonetheless declined to join EU sanctions regimes against Russia, and that maintains working relations with Moscow, Beijing and a range of states the West has isolated.

That balancing act gives Belgrade a recurring role in stories about sanctions and connectivity. Because Serbia stays outside EU sanctions and its airspace is open to carriers barred from NATO and EU skies, Belgrade's Nikola Tesla Airport functions as a routing hub between East and West. In the Iran conflict it surfaced as the first reported intermediate stop when flights resumed between Tehran and Moscow after roughly two months of air isolation, a practical workaround that illustrated the limits of Western sanctions over third-country airspace.
