The political advance of the Ottoman Empire in the Balkans was certainly a great challenge for the Christian powers of Europe. It was the first time that Christendom was basically on the defensive in front of a military colossus that announced its supremacy in the Balkans, but also on the entire old continent. It was at that time that the unparalleled personality of Iancu de Hunedoara emerged north of the Danube. Through energetic actions he tried to impose his will north of the Danube. However, the creation of a confederation under his leadership that would actively participate in anti-Ottoman military operations came up against, on the one hand, the political choices of the extra-Carpathian Romanian countries and, on the other, the intentions of the Polish royalty to maintain their influence in Moldavia. This was one of the main causes of the crisis in Moldavia before Stephen the Great took the throne.
