The once-powerful Kingdom of Bohemia has been reduced by the 1470s to the territory of Bohemia proper.

The Bohemian War begins when the Kingdom of Bohemia, ruled by the Hussite king, George of Poděbrad, is invaded by the king of Hungary, Matthias Corvinus, under the pretext of returning Bohemia to Catholicism.

Matthias' invasion is largely successful, leading to his acquisition of the southern and eastern parts of the country.

Its core lands, however, centered on Prague, are never taken.

Ultimately both Matthias and Poděbrad proclaim themselves king, though neither ever acquire all the necessary subordinate titles.

When Poděbrad dies in 1471, his successor Vladislaus II continues the fight against Matthias.

In 1478, the war ends following the treaties of Brno and Olomouc.
