Jean I

Lord of Monaco in 1427, Jean I was faced with serious political instability, rendering it difficult to consolidate his authority. This political instability led him to infeudate Menton and Roquebrune to the Count of Savoy. Nevertheless, Jean I made careful provisions for his succession. His will, in 1454, made it possible to pass on the lordship to daughters of his Catalan son, if he did not produce a male heir. This text laid the foundations for the basic rules of succession of the Grimaldi dynasty up until modern times, providing the opportunity, if there was no male heir, for the dynasty to be replaced, while still maintaining the Grimaldi name and coat of arms.
