5 June 1419

Sons of Rainier II, Jean, Ambroise and Antoine, bought back Monaco from Genoa and ruled it jointly until 1427. After Antoine's death, Jean bought out his brothers in exchange for the rule over منتون and Roquebrune.
Monaco was occupied by the دوقية ميلانو under the governorship of Genoese Biagio Assereto from 3 October to November 1436.
On 20 November 1441, Jean gained sovereignty for Monaco.
Jean's testament replaced the Lex Salica with Male-preference primogeniture [لغات تانيه], thus allowing for female succession (then British system).
Starting in 1612, Honoré II was the first Monegasque ruler to adopt the personal style of Prince, to which the Grimaldi rulers of Monaco were already entitled to through their possession in Italy. Monaco was recognized as a sovereign principality [لغات تانيه] by فيليب الرابع ملك اسبانيا in 1633 and by لويس التلاتاشر ملك فرنسا of France in the Treaty of Péronne [لغات تانيه] of 1641.
