List of rulers of Monaco
The Grimaldis used the title of Lord until 1612. Then, Lord Honoré II started using the title of Prince, thereby becoming the first Prince of Monaco. Afterwards, Honoré II secured recognition of his independent sovereignty from Spain in 1633, and then from France by the Treaty of Péronne in 1641. Since then the area has remained under the control of the Grimaldi family to the present day, except when under French control from 24 February 1793 to 17 May 1814.
