Despite such a level of tolerance, Poles were quite active demanding independence and political rights, including the notable Kraków uprising of 1846. Poles joined the Revolutions of 1848 to support other nations fights against Austria, most notably the Hungarian Revolution of 1848. Polish General, Józef Bem continued the conflict against the Austrian rulers and gave great difficulty to the Austrian Army. The revolution stopped only after Russian reinforcement arrived and quelled the revolution with blood. From then, Austria became increasingly harsh towards the Poles but remained the most tolerant of the partitions.
