Principality of Monaco

1297 CE – present · capital Monaco

A rock on the Riviera seized by the Grimaldis in 1297 and still ruled by them, now one of the world's smallest and richest sovereign states.

Origins

In January 1297 François Grimaldi, a Genoese Guelph exile, took the fortress of Monaco disguised as a Franciscan friar, an event recalled in the monk on the family arms. The Grimaldis lost and regained the rock several times before establishing lasting control in the 15th century.

Rule and society

The Grimaldis governed as lords, later princes, balancing between Genoa, Spain, France and Savoy. Honoré II placed Monaco under French protection in 1641 and adopted the title of prince. Revenues came from tolls, olive oil and citrus from Menton and Roquebrune, until Charles III founded the Monte Carlo casino in 1863.

To the present

Monaco was annexed by France in 1793 and restored in 1814 under Sardinian protection. Menton and Roquebrune broke away in 1848 and were sold to France in 1861. Constitutions of 1911 and 1962 limited princely power; under Rainier III and Albert II it became a banking and tourism centre.
