Troilo I de' Rossi

A son of Giovanni Rossi "il Diseredato" and Angela Scotti Douglas,[1][2] he was born in San Secondo.

He took part in Louis XII of France's conquest of the duchy of Milan in 1500, during which many lands taken from his grandfather by Ludovico il Moro and ending up in the hands of members of the Sforza family were restored to him.

However, it proved impossible to restore to him all the lands his family had controlled in the time of Pier Maria II and it was possibly as compensation for this fact that Louis made him marquess of San Secondo on 15 August 1502.

[3] He restored the Rocca dei Rossi at San Secondo, rebuilding its bastions and towers, which had been demolished during the war with the Sforza, and expanding the defensive perimeter.

He died there in June 1521, leaving the marquisate weak - his heirs were still in their minority and so the Rossi of Corniglio tried to take advantage of the situation with a force led by Filippo Maria and Bernardo, descendants of Guido de' Rossi, the son Pier Maria II had chosen to succeed himself.
