The oldest son of Rainier I by his first wife, Salvatica del Carretto, Charles was forced to flee into exile following the Rock of Monaco falling into Genoese control on April 10, 1301.
[2] After thirty years of Genoese rule, Charles retook the Rock on 12 September 1331, and ruled until his death, when the Rock was again conquered by the Genoese army.
Also he was Baron of San Demetrio, in the Kingdom of Naples.
On 29 June 1352, Charles designed a co-rulership of Monaco between his uncle Antonio (his father's youngest brother), and his own sons, Rainier II and Gabriele.
