The treatise follows the development of the mutual relations of the opposition group of the Bohemian Catholic nobility of the so-called League of Zelená Hora and Holy Roman Emperor Frederick III of Habsburg, whose support was besides the Pope to legitimate the resistance of the aristocracy against King George of Poděbrady. It shows the property interests of the leading representatives of the League in Austria, reveals the ties to the personalities of Frederick’s court, assesses the impact of the Affair with Poisons from 1465 and the motives of the parties involved. The emperor’s support was not enough to gain military assistance from the Holy Roman Empire, so in the end the League of Zelená Hora offered the Bohemian throne to the Hungarian king Matthias Corvinus. After the death of George of Poděbrady, this organization lost any real interest in the continuation of the war, tried for a certain balance between the emperor and the king of Hungary Matthias Corvinus, but managed to avoid Corvinus using his personal conflict with Frederick III from 1476–1477 to his own advantage.
