Popiel

According to the chroniclers Gallus Anonymus, Jan Długosz, and Marcin Kromer, as a consequence of his bad rule he was deposed, besieged by his subjects, and eaten alive by mice in a tower in Kruszwica.

As the legend goes, Prince Popiel was a cruel and corrupt ruler who cared only for wine, women, and song.

He was greatly influenced by his wife, a beautiful but power-hungry German princess.

[1] Because of Popiel's misrule and his failure to defend the land from marauding Vikings, his twelve uncles conspired to depose him; however, at his wife's instigation, he had them all poisoned during a feast (some believe that she committed the act herself).
