Józef Zachariasz Bem (, ; March 14, 1794, Tarnów – December 10, 1850, Aleppo) was a Polish general, an Ottoman pasha and a national hero of Poland and Hungary, and a figure intertwined with other European nationalisms. Like Tadeusz Kosciuszko (who fought in the American War of Independence) and Jan Henryk Dabrowski (who fought alongside Napoleon Bonaparte in Italy and in the French Invasion of Russia), Bem fought outside Poland's borders for the future of Poland anywhere his leadership and military skills were needed.
