Stefan Florian Garczyński (13 October 1805 or 1806 – 20 September 1833) was a Polish patriot and Romantic poet, a passionate Messianist.
In protest at Chabad messianism, Rabbi Shaul Shimon Deutsch started a split-off group known as Chabad-Liozna.
He has been trying to offer "a reinterpretation of the revolutionary theory and marxism from the perspective of messianism and Jewish mystic, and vice versa".
