1791 Honoré Gabriel Riqueti comte de Mirabeau a leader of the early stages of the French revolution. A noble, before 1789 he was involved in numerous scandals that left his reputation in ruins. However during the early years of the French Revolution he rose to the top and became the voice of the people. A successful orator, he was the leader of the moderate position, favoring a constitutional monarchy built on the model of Great Britain. When he died he was a great national hero, even though support for his moderate position was slipping away. The later discovery that starting in 1790 he was in the pay of the king and the Austrian enemies of France caused his disgrace. Historians are deeply split on whether he was a great leader who almost saved the nation from the Terror, or a venal demagogue lacking political or moral values, or a traitor in the pay of the enemy

1851 Nangklao the third monarch of Siam under the House of Chakri, ruling from 21 July 1824 to 2 April 1851. He succeeded his father, Buddha Loetla Nabhalai, as the King of Siam. His succession was unusual according to the traditions because Nangklao was a son of a concubine rather than a queen. His accession was perceived by foreign observers as having usurped the prior claim of Prince Mongkut, who was a legitimate son of Buddha Loetla Nabhalai born to a queen, Srisuriyendra. Under the old concept of Thai monarchy, however, a proper king must emulate Maha Sammata in that he must be "elected by the people." Ironically, Prince Mongkut may have later contributed to this misconception, when he feared that his own accession might be perceived by foreign observers as a usurpation
