In August 1434 Taddeo d'Este was engaged in fighting in Romagna with the troops of Bologna, and was taken prisoner, being released after the intervention of the Marquess of Ferrara. In March 1435 he was given the task of foiling an attempt by Marsilio da Carrara to capture Padua. After he had succeeded, in April 1435 he was admitted to the ranks of the Venetian nobility, with his children and heirs, and admitted to the Great Council of Venice. The Venetians awarded him a palace in their city of Padua.
