The Prince of Monaco was an
absolute ruler until the
Monegasque Revolution of 1910 forced him to proclaim a constitution in 1911. In July 1918, a treaty was signed providing for limited French protection over Monaco. The treaty, written into the
Treaty of Versailles, established that Monegasque policy would be aligned with French political, military, and economic interests. One of the motivations for the treaty was the upcoming
Monaco Succession Crisis of 1918. While Prince
Louis II's sympathies were strongly pro-French, he tried to keep Monaco neutral during
World War II but supported the
Vichy French government of his old army colleague, Marshal
Philippe Pétain. Nonetheless, his tiny principality was tormented by domestic conflict partly as a result of Louis's indecisiveness, and also because the majority of the population was of Italian descent; many of them supported the
fascist regime of Italy's
Benito Mussolini. On 11 November 1942, the
Italian Army invaded and occupied Monaco. Soon after in September 1943, following
Mussolini's fall in Italy, the
German Army occupied Monaco and began the
deportation of the Jewish population. in 1944 Among them was
René Blum, the French Jew who founded the
Ballet de l'Opera in Monte Carlo. He was arrested in his
Paris home and held in the
Drancy deportation camp outside the French capital before being transported to the
Auschwitz concentration camp, where he was later killed. Blum's colleague
Raoul Gunsbourg, the director of the
Opéra de Monte-Carlo, helped by the
French Resistance, escaped arrest and fled to
Switzerland. In August 1944, the Germans executed
René Borghini,
Joseph-Henri Lajoux and
Esther Poggio, who were Resistance leaders. The country was liberated on 3 September 1944 by Allied forces. Prince
Rainier III ascended to the throne following the death of his grandfather, Prince Louis II, in 1949. The revised
Constitution of Monaco, proclaimed in 1962, abolished capital punishment, provided for female suffrage, established a
Supreme Court to guarantee fundamental liberties and made it difficult for a French national to transfer his or her residence there. In 1993, Monaco became a member of the
United Nations with full voting rights. ==21st century==
