Unsurprisingly, given the conditions under Imperial Russia, the Jews participated in a number of Polish insurrections against the Russians, including the Kosciuszko Insurrection (above), and the January Insurrection (1863) as well as the Revolutionary Movement of 1905. Jewish student Michał Landy was killed by Russians during a Polish demonstration in Warsaw, 1861. Christians weren't allowed by the police to participate in his burial.
