The pope had excommunicated Ottocar, and the terrors of the curse of the pope, were driving captains and nobles from his service.
The proud spirit of Ottocar, after a terrible struggle, was utterly crushed, and he humbly sued for peace.

The terms were hard for a haughty spirit to bear.

The conquered king was compelled to renounce all claim to Austria and several other adjoining provinces, Styria, Carinthia, Carniola and Windischmark; to take the oath of allegiance to the emperor, and publicly to do him homage as his vassal lord.

To cement this compulsory friendship, Rhodolph, who was rich in daughters, having six to proffer as bribes, gave one, with an abundant dowry in silver, to a son of Ottocar.
The day was appointed for the king, in the presence of the whole army, to do homage to the emperor as his liege lord.

It was the 25th of November, 1276.
