During the Revolution, France confiscated all the Princes' lands, and in the middle of the 19th century, Monaco lost Menton and Roquebrune, which seceded. However, Princess Caroline, wife of the reigning Prince Florestan I, came up with a brilliant idea that saved Monaco. She proposed setting up a gambling establishment on the Rock, which led to the concession being granted to two Parisian journalists, Albert Aubert and Léon Langlois, to open a bathing establishment with a games room, concert hall, and other entertainments. The concession was granted in return for the surrender of a quarter of the profits with a minimum guarantee of 25,000 francs, the construction of hotels and villas, the creation of a printing works publishing at least one weekly newspaper, the introduction of boat and omnibus services from Monaco to Nice, and improvements to the port.
