The Karaites of Lithuania, and of West Ukraine were originally known as Polish Karaites. They were the Karaites who published the Minhag HaQaraim in the Austro-Hungarian Empire and were finally allowed to establish their own community in Trakai in 1864. It is from this group that the Firkovich Family came. All the books adopted by the [[Karaimites]] were published by this group. However, this group also published Hizzuk Emunah which was a forgotten and unknown book both to [[Karaimites]] and to the [[Crimean Karaites]] from Egypt before Mordechai Alfandari introduced it to themthe latter.
