When Alfonso II died without heirs in the October 1597, Cesare claimed the duchy of Ferrara.[1]Pope Clement VIII raised an army and Cesare, denied French assistance, retreated to Modena.[1][2] His capital was moved to Modena, which he entered on January 1598.[3] Cesare's first years were troublesome: he had to face the quarrels between the Modenese and Ferrarese nobles who had come with him, the attempt at independence of Maro Pio of Sassuolo, and a war against Lucca for the possession of Garfagnana.
