Guido de' Rossi

Guido de' Rossi (c. 1440 - 1490) was an Italian condottiero.

Life He was almost certainly born in the castle at San Secondo, the residence of his father Pier Maria II de' Rossi. His mother was Pier Maria II's wife Antonia Torelli. Little is known of his youth: he served in the duke of Milan's army and in 1478 was made governor of Pontremoli and Lunigiana. He is known to have been a condottiero and man-at-arms in 1479. In his will in 1464 Pier Maria II made Guido, his brother Bertrando and one of his illegitimate sons his heirs. This disinherited Pier Maria II's eldest son Giovanni.

Guido came to his father's aid during the Rossi War against Ludovico il Moro and was thus declared a rebel by the duchy of Milan. He successfully held the Rocca dei Rossi in San Secondo against a Sforza siege under Antonio del Vasto (son of the marquess of Saluzzo), who was killed during the siege. Guido died in Venice in 1490 and was buried there at Santa Maria della Carità.

Marriage and issue He married Ambrosina Borromeo, with whom he had six children: Bernardo de' Rossi, bishop of Treviso Giovanni Maria Filippo Maria de' Rossi, his heir Ettore Betrando, died young in Venice Giovanna, married Gianbattista Malaspina, marquess of Spinola
