At present, Monaco is the world’s second-smallest state (Wikipedia mentions both 1,64 and 1,95 km², although another source mentions 1,49 km²) after the Vatican (0,44 km²) as well as the most densely populated (at 23.660 inhabitants/km²). Yet at one time, Monaco was decidedly less mini than it is now. Before being dismembered in the second half of the nineteenth century, Monaco covered around 30 km², which is about half the size of San Marino.

 In 1997, the Grimaldi dynasty celebrated its 700-year dominion over Monaco. These philatelic references to former ‘greatness’ (again found at Dan’s Topical Stamps) were issued at that time. The stamp in the upper left corner shows Monaco in the 13th century. Monaco’s origins lie in a land grant by Emperor Henry VI of the Holy Roman Empire in 1191, but  it was re-founded early in the thirteenth century as the western outpost of Genoan control. On this map, Genoa’s territory can be seen extending westward on the Côte d’Azur to include Monaco. In 1297, Francesco Grimaldi (Il Malizio – ‘the malicious’ or ‘the cunning’) and some fellow plotters captured the fortress on Monaco rock disguised as Franciscan monks – hence the monks with swords in Monaco’s coat of arms.

There is some confusion whether Monaco was named after this incident (Monaco is Italian for ‘monk’) or whether its name dates to the much earlier Greek period (the Greek colony of Massilia – later to become Marseilles – called the local Ligurians monoikoi, possibly because of their habit of living individually, monoikos meaning ‘single house’; or as a reference to Hercules, who is supposed to have lived alone there. In Antiquity, Monaco had a temple dedicated to Hercules and was in fact called something akin to Port Hercules).  

The map in the upper right corner shows the shrinkage which occurred in the nineteenth century. Monaco succeeded in tearing loose from Genoa and had its independent status confirmed by the King of France and the Duke of Savoy in 1489. But in the centuries that followed, the Grimaldis presided over a territory under increasing pressure from the consolidating nation-states surrounding it. From 1793 to 1814, Monaco was even occupied by revolutionary France.

The Congress of Vienna designated Monaco as a protectorate of the Kingdom of Sardinia from 1815 to 1860, whereafter the surrounding county of Nice (and the Duchy of Savoy) was ceded to France. During this time, the Grimaldi-ruled towns of Menton and Roquebrune (which had been acquired as early as 1341) declared independence, hoping for annexation by Sardinia. The unrest ended in 1861, when Monaco ceded both towns (95% of its territory) to France in exchange for 4 million francs.

Having lost so much terrain on land, Monaco turned to the sea. The map on both lower stamps shows the amount of territory gained by landfill (plus dates of completion); as well as the extension of territorial waters to 12 nautical miles in 1984. The panoramic view at the very bottom is of the present-day western half of Monaco.
