 As her dowry was never paid, the claims against it continued long after her death.Reprisals taken against Milanese merchants in London in 1464 to recover this sum were probably related to the dowry, and these grew to be so debilitating that the merchants were forced to stop trading with England in 1471, prompting Galeazzo Maria Sforza, the Duke of Milan, to ask his envoy in England to plead for relief.In 1486, a letter to the new Duke of Milan, Gian Galeazzo Sforza, demanded payment of the dowry.
