 In March 1849, Mikhail Bakunin, a Russian Pan Slavic revolutionary, visited Prague and suggested to organize an armed uprising in Prague and several German-speaking cities as a response to post-1848 political reaction.The date of the uprising was set on May 12, 1849, but due to amateurish organization police took the organizers into custody on the night of May 9 to May 10 1849.Prague and a few towns were put under a state of emergency (also called "the siege", "stav obležení"), press was put under censorship by the military and a military commission was established to investigate the conspiracy.
