Monaco is a tiny sovereign city-state on the Mediterranean coast of the French Riviera, surrounded on land by France. The second smallest country in the world after the Vatican, and the most densely populated, it is a glamorous principality ruled by the ancient Grimaldi dynasty and synonymous with wealth, luxury, and high society. Famous for its casino at Monte Carlo, its harbour full of yachts, and its Formula One Grand Prix run through the streets, Monaco draws the rich of the world with its glittering setting and its celebrated absence of income tax.

Monaco's history is the story of the Grimaldi family, one of the oldest ruling dynasties in the world, who seized the fortress on the rock in 1297, famously by trickery, with one of them disguised as a monk, and have held it, with interruptions, ever since. The little state survived under the protection of more powerful neighbours, especially France and Spain, through the centuries. In the nineteenth century it lost most of its territory but secured its survival, and the founding of the casino at Monte Carlo soon afterwards began its transformation into a playground of the wealthy.

Monaco is a minuscule strip of land on the Mediterranean coast, hemmed between the sea and the steep, dramatic slopes of the Maritime Alps that rise immediately behind it. With almost no level ground, the principality is intensely built up, its tall buildings stacked on the hillsides and crowded around its harbour, and it has repeatedly expanded by reclaiming land from the sea to make room for more. The result is one of the most densely packed and developed pieces of land on Earth, a vertical city-state of terraces, tunnels, and a famous deep-water port.

The flag of Monaco has two horizontal bands of red over white, the heraldic colours of the ruling House of Grimaldi, derived from the family's ancient coat of arms. The simple, bold design is one of the oldest national flags in continuous use. It is, however, virtually identical to the flag of Indonesia, which differs only in its proportions, a coincidence between two nations on opposite sides of the world, each flying red over white as an emblem of a heritage entirely its own.

Monaco is a Roman Catholic country, and Catholicism is the official state religion, reflecting the deep historical ties of the principality and its ruling family to the Church. The faith is woven into the ceremonial life of the state and the calendar of the small nation, and the cathedral of Monaco, where members of the princely family are married and buried, including Princess Grace, is an important national landmark. While religious freedom is guaranteed and the cosmopolitan population includes many faiths, the principality's Catholic heritage remains central to its official identity.

Monégasque cuisine reflects the principality's Mediterranean and Provençal setting, with strong ties to the cooking of neighbouring France and nearby Italy. Local specialities include barbagiuan, a fried pastry stuffed with chard and cheese, and socca, a thin pancake made from chickpea flour, both shared with the surrounding Riviera. Seafood from the Mediterranean, olive oil, vegetables, and herbs feature throughout, alongside the refined French haute cuisine of Monaco's celebrated restaurants. The food thus ranges from humble local street snacks to some of the most luxurious dining in the world.

Monaco has essentially no agriculture, a consequence of its tiny size and the near-total absence of open land in one of the most densely built environments on the planet. There are no farms, fields, or significant cultivation, and the principality imports all of its food, chiefly from neighbouring France. Its economy is instead entirely urban and service-based, resting on tourism, the famous casino and gaming, banking and finance, luxury real estate, and its status as a tax haven, which together have made this landless city-state one of the wealthiest places in the world.

The seizure of the rock by the Grimaldis in 1297 and the dynasty's long survival as one of the oldest in Europe define Monaco's history, while the founding of the Monte Carlo casino in the nineteenth century launched its modern fame and fortune. In the twentieth century the fairytale marriage of Prince Rainier III to the Hollywood star Grace Kelly captivated the world and cemented Monaco's glamorous image, though it ended in tragedy with her death in a car accident. The principality remains a symbol of wealth, sport, and high society.

Monaco has a population of around 38,000 people packed into its tiny area, making it the most densely populated country in the world. Remarkably, native Monégasques are a minority in their own country, outnumbered by French, Italian, and other foreign residents drawn by the principality's wealth and tax regime, among them many of the world's richest people. French is the official language, with Italian, English, and the traditional Monégasque dialect also heard. The population is concentrated in the principality's famous districts, including Monte Carlo, on its crowded Mediterranean hillsides.
