Polish Karaites
From Wikinoah English
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.
Seraya Shapshal came to rule the group in 1928.
