The king was strictly against making alliances. When his neighbour king came to his empire, he was willing to make an alliance with him by offering the hand of his daughter for the king's son. This way, the both kings knew that they will be very strong with this alliance.
However, the king Brutus had other plans. He did not see the neighbour king as an ally. When the minister asked, Brutus replied that he is not an ally. And eventually, his empire crumbled.
