History
The Grimaldis, a Genoese family of the Guelph faction, seized the fortified rock of Monaco in 1297 — by tradition through François Grimaldi, who talked his way in disguised as a monk, an episode still marked by the two sword-bearing monks on the coat of arms. Over the following centuries the family held Monaco along with the nearby towns of Menton and Roquebrune, under the protection at various times of Spain, France, and Sardinia.
In 1848 Menton and Roquebrune broke away, and an 1861 treaty confirmed their loss to France in exchange for French recognition of Monaco's independence, leaving the principality at roughly its present tiny size and close to bankruptcy. The remedy was the casino: Prince Charles III chartered the Société des Bains de Mer, and the gaming house that opened in 1863 in a new district named Monte-Carlo — "Charles's Mount" — after him was so profitable that Monaco abolished income tax in 1869.
That decision shaped everything since. The Monte-Carlo Rally began in 1911 and the street-circuit Grand Prix in 1929. Prince Rainier III married the American actress Grace Kelly in 1956; a 1962 dispute with France over tax was settled by a new constitution and an agreement that French residents would still be taxed by France while others would not. Monaco joined the United Nations in 1993. Prince Albert II has reigned since 2005, and land reclaimed from the sea has enlarged the country by about a fifth, most recently with the Mareterra district completed in 2024.
- Monaco: The Rock and the Casino — A fortress seized by a Genoese exile in 1297 and held by the Grimaldis ever since — shrunk to two square kilometres in 1861, rescued by a gambling concession, and reinvented as the world's densest enclave of wealth
